Horse Castration Process

For my Horse Production class
------------------------------------------------

Horse Production
October 1, 2010
Horse Castration Process
The first thing to consider when castrating a horse is its age. The prime age to do so is yearlings; however it is possible as soon as the testicles have dropped which may be as early as birth. However castration at birth is undesirable due to the young colt’s immune system is still weak. The next aspect to consider is health. If a horse is ill the risk of infection increases tremendously. One more major component to consider is weight – to have proper dosage. One of the last preferable characteristic s of a horse that is to be castrated is for the horse to at the very least be halter broke, and for the horse to have its tetanus shot.
The first step to castrating the horse is to administer an antibiotic and then an anesthetic made up of ketamine and diazapan (also known as valium – to ease the process of putting the horse to sleep). The risks of anesthetics include but are not limited to over dosing; the horse comes in or out of anesthesia violently. The cut made when removing the testicle can also cause (in rare cases) for the intestines to spill out. It is also preferable to not suture the incision to allow the cut to drain.
The veterinarian recommends exercising the horse to help reduce swelling.
The first incision is made over the testicles using a scalpel. You pull the testicle through the incision, and strip away the fat. Clamp the testicle and wait for the blood flow to slow, and then pull away the testicle. Wait for the vein to clot for another minute, and then release the clamp. This helps regulate the hemostasis. You can stop the flow of blood with and emasculator.
You can optionally use a triple drip to help maintain anesthesia and relax the muscles of the horse. A preferable drug used in the triple drip is xylazine. Xylazine is a drug that is used for sedation, anesthesia, muscle relaxation, and analgesia in animals such as horses.
Congratulations, you have a castrated horse!

Feeds and Nutrition

These are snippets of research I did during my feeds class to come in better prepared each day
----------------------------------------------------------

Canola Meal
The common name for the canola is called the “rapeseed plant”, but with reduced fatty acid, eruric acid and glucosinolates. Canola meal is left-over from the processing of canola oil. Canola seeds are cleaned, preconditioned, processed (by being crushed and heated), the oil and hexane are then extracted, the oil refined where components such as phospholipids, maculaginous gums, free fatty acids and other parts are removed from the oil but added to the canola meal.


Fat Breakdown

The chemical compound that breaks down fat is called bile, which is released by the liver and stored in the gallbladder. Bile breaks down fat into small droplets, or “fatty acids” so that when released into the gastrointestinal tract it can be absorbed and utilized by the body.

ATP and Bushel Weight
1) How many ATP's are generated under ideal conditions from 3 moles (3 units) of Maltose. Remember that maltose is a disaccharide.
You gain 6 moles of ATP per mole of Maltose. That means (6*3) you receive 18 moles of ATP from 3 moles of Maltose.

2) Identify the bushel weights for the following grains: a - #2 corn, b - barley, c - oats, d - milo.
A.      #2 Yellow Corn has a standard of 56 lbs per bushel
B.      Barley has a standard of 48 lbs per bushel.
C.      Oats have a standard of 32 lbs per bushel.
D.      Milo has a standard weight of 56 lbs per bushel.

Essential Fatty Acid
Omega-6 (linoleic acid) and omega-3 (linolenic acid) fatty acids are essential for animals. There are two types of Linolenic Acids, Alpha Linolenic Acid (ALA) and Gamma Linolenic Acid (GLA). Linoleic acid has 18 carbons and 2 double bonds. Both linolenic acids have 18 carbons each and 3 double bonds each.

Ketosis and Milk Fever
Milk Fever, also known by its clinical name, “Parturient Paresis”, is paralysis of mature dairy cows that occurs most commonly at or soon after parturition. The onset of lactation severely reduces calcium, and serum phosphorus. This makes the cow hyperglycemic.
“Ketosis is a common disease of adult cattle. It typically occurs in dairy cows in early lactation and is most consistently characterized by partial anorexia and depression. Rarely, it occurs in cattle in late gestation, at which time it resembles pregnancy toxemia of ewes. In addition to inappetence, signs of nervous dysfunction, including pica, abnormal licking, incoordination and abnormal gait, bellowing, and aggression are occasionally seen. The condition is worldwide in distribution, but is most common where dairy cows are bred and managed for high production.
The pathogenesis of bovine ketosis is incompletely understood, but it requires the combination of intense adipose mobilization and a high glucose demand. Both of these conditions are present in early lactation, at which time negative energy balance leads to adipose mobilization and milk synthesis creates a high glucose demand.”


Spleen
The spleen is part of the lymphatic system; it is an organ that removes old or damaged red blood cells and helps cleanse the blood. It also produces white blood cells, and acts as a reservoir for blood. It is located in the upper abdomen near the stomach in most mammals. 







Synthesis Essay

Written for English 201 concerning our minds and why we must teach ourselves to learn.

Synthesis Essay
If a question was asked, any question, today’s automatic answer is to find the solution through technology. We’ve grown dependant on the ticking of clocks, the virtual world of the internet, and the convenience of our phones. A difficult concept for us to grasp, however, is merely thirty years ago most of these did not existed.
So how has this affected our minds?  Have we turned our brains into a living computer, or are we so dependent on outside answers that we’ve ceased thinking for ourselves? In today’s society we’ve entered a state of ignorant bliss about how little knowledge and wisdom we truly hold. Neil Postman (1984), the author of “Amusing Ourselves to Death” and an educator, tackled the now apparent fact that unlike George Orwell’s prediction that our rights to thinking would be ripped away, Aldous Huxley’s prediction that we will gladly hand them away voluntarily has become more and more true. Both Orwell and Huxley are English authors. (Postman, 1984)
We allow our information to be fed to us by the television which trivializes it, and the internet which blends opinion and fact together so intricately that it is intermixed beyond comprehension. Yet we process this information, we build our thoughts and opinions around what the other misinformed populous insists is fact. But we are aware of the lies and incomplete facts out there, so when the truth does come out, it is unrecognizable.
Nicholas Carr (2008) wonders of our ability to separate how we think and how a computer processes input in his article “Is Google Making Us Stupid?” He complains of a recent inability to pay attention to books for long periods of time. He blames this on receiving his information online in quick snippets, and reading novels has become a chore to him. Carr mentions Lewis Mumford, a cultural critic, who speaks of the invention of the clock. He degrades the clock, saying “In deciding when to eat, to work, to sleep, to rise, we stopped listening to our senses and started obeying the clock.” (Carr, 2008, p. 4)
Is it true that we’ve handed over not only our minds, but our bodies to technology? We are becoming slaves to others to feed us the information we search, and to tell us how and when to do what instinct and Mother Nature had guided us to do for hundreds of thousands of years. And we’re paying the price.  
For thousands of years we’ve read and written books, which helped pass down wisdom to younger generations. Books created worlds we’ve never seen, they questioned our philosophical purpose, and they answered it. From manuals to stories, books have been handed down as a collection of knowledge; but for the first time in millennia we’re raising entire generations who have never read a novel, short story or even a poem. David McCullough (2008), author of “The Love of Learning” defines for us the difference between facts and wisdom. Data is irrelevant until we have made the judgment to make it important and learn from it. We cannot memorize facts and call ourselves learned; we must look a layer deeper and find what the facts mean to us. “Learning is acquired mainly from books, and most readily from great books.” (McCullough, 2008, p. 2) Without books we are only being fed data, numbers and words without any true meaning. (McCullough, 2008)
Our ability to understand and think about problems creates an ability to understand beyond the ordinary and think complexly on a situation. When told the rate of a bowling ball’s fall, and the opposing force of air fighting against gravity, we can think about this and then ask something that never came up, “Why did we drop the bowling ball? Will a ten pound fall faster than an eight pound bowling ball? And what if the ball were square?” Science is built on this foundation of thought, and with our technologies answering our questions - people have stopped asking the questions all together.
In the article “O Americano, Outra Vez!” written by Richard P. Feynman, an American scientist and educator, the consequences of learning but never understanding concepts was made clear. In Brazil they taught physics as young as elementary school, however not a single student taught by Feynman in Brazil seemed to be able to comprehend what the words meant beyond just data. (Feynman, 1985) This inability to have opinions and questions over facts we learn impedes our ability to really understand what we learn.
Because of the convenience of information today we’ve stopped asking if this needs verification. We’ve become lazy in our advancement, and expect that sort of work and authentication to be done by someone who we may say is “smarter than I”. What today’s society doesn’t seem to understand is that this attitude has stunted our growth as the human race, and we are reaching a stalemate of blissful ignorance, much as Huxley predicted.
But this is not to say technology is the sole root of our decreasing intelligence. The blame lies namely in our attitude towards the world of information that lies in our gadgets. Rather than utilizing this sort of resource as a layer of foundation to go beyond in discovery in a way that was impossible before, we let the endless array of data sit there only to be utilized at our discretion, which is not often.
This state of unintelligence is not incurable, and perhaps turning to the root of knowledge and wisdom that has accumulated over our history, otherwise known as books, can turn around our ability to simply think. A book has the amazing capability to let us read in between the lines, and gives us the ability to absorb information much more efficiently than this “skimming” we find ourselves doing when facing screens. We engage our minds when reading a book, and discover new ideas in every novel, short story and poem. And maybe all we need is to reawaken this amazing brain power we have long forgotten to use the information our technology hands us to the best of our ability.
Our brain retains a wonderful ability to maintain enormous amount of information, and however much knowledge we may lack we can always remedy this by settling down with a good book. While our computers, phones, and television and provide an almost endless stream of pure data to us, we must learn how to properly utilize this information to the best of our benefit. We can choose to think logically with the knowledge handed to us, and to continue our growth. The world can carry on its advancements to improve the lives of all that inhabit it, but only if the individual continues progressing.
William J. Perry, Jr. (1970) said it best in his article “Examsmanship and the Liberal Arts” when he defined the words bull and cow. Bull is information that has relevancies but have minimal to no data to back it up, and cow has data but no relevancies. (Perry, 1970) Our technology is full of cow, and our minds are full of bull. Once we can find a way to combine these forces, we will never stop progressing. Perry (1970) summed the dangers of a chronic “cow”,
“These are delicate matters. As for cow, its complexities are not what need concern us. Unlike good bull, it does not represent partial knowledge at all. It belongs to a different theory of knowledge entirely. In our theories of knowledge it represents total ignorance, or worse yet, a knowledge downright inimical to understanding. I even go so far as to propose that we award no more C’s for cow. To do so is rarely, I feel, the act of mercy it seems. Mercy lies in clarity.” (p. 8)
Perry is arguing we must first become aware of and recognizing cow, and to correct it upon sight.
This requires we learn to learn, which means we should delve our minds into books and others personal wisdom and experience. In only this method can we expand our own minds and become aware of cow, or bull, and teach ourselves to think beyond what is given to us. We learn to analyze and experiment, and in this manner we can progress into a better future – not only for ourselves, but for future generations.

Hip Dysplasia in Pregnant Dogs


Written for my Animal Reproduction class. Concerns physiological description of hip dysplasia occurring in a pregnant bitch.
----------------------------------------------------------- 





Hip Dysplasia in Pregnant Dogs and Puppies
Rachel M. Counts


 
Hip dysplasia is a prevalent problem in large canine breeds, and is influenced by genetic and environmental factors. It concerns the abnormal development of the acetabulum and coxofemoral joint, where the femur head meets the pelvis. The major abnormalities occur between the muscles surrounding or on the hip joint, and the development of bone at the hip joint. Rubbing of bone, or joint laxity occurs in the dog and causes the dog to be unstable and experience pain or stiffness in the hind legs.
Hip dysplasia is detected using radiographic techniques, and it measured by evaluating nine different areas of the hip joint. The craniolateral acetubular rim, caudal acetubular rim, fovea capitus, and other important points on the hip are observed for abnormalities to grade the canine on hip dysplasia and the degree of it. (Orthopedic Foundation for Animals, 2010)
Certain treatments are available to help alleviate any pain or discomfort the dog may feel. Surgical treatment is an option, but in this case we will be observing a dog with only moderate hip dysplasia that is pregnant.
Anti-inflammatory drugs are some of the most common drugs given to dogs with hip dysplasia, but other drugs meant to control pain, encourage cartilage repair, increase mobility and slow down the breakdown of bone in the joints are also administered. These common drugs include aspirin, carprofen etodolac, cosequin®, glycol-flex®, and adequan®. (Plotnick, 1999) However safe use in pregnant dogs has not yet been established for the medicines carprofen, etodolac, cosequin®, glycol-flex® and adequan®. (Rimadyl, 2011) (Zoologist, 2010) (VetRxDirect, 2011) (1-800-PetMeds, 2011) (Adequan Canine, 2005) Aspirin is known to cause birth defects. So drug control is not an option for pregnant dogs with hip dysplasia. (Randall, 2011)
Other treatments the can help reduce the symptoms of hip dysplasia include a strict diet to prevent weight gain or to promote weight loss, reduction of exercise on hard surfaces, physical therapy to tone muscles (such as underwater therapy), and optionally joint fluid modifiers. (Kahn, Line, & Merck & Co., 2010)
Our pregnant dog we are observing has recently copulated. Higher estrogen levels will help promote stronger bone health to aid in carry her new puppies, but eventually the added weight will stress her hips to a point where she may be completely immobile, and in great pain due to the lack of medications she can take.
However, the higher estrogen may account for the new puppies bone developing. (Steinetz, Williams, Lust, Schwabe, Büllesbach, & Goldsmith, 2008) During pregnancy and the lactation period afterwards can account for up to 5% bone mass loss. (Karlsson, Ahlborg, & Karlsson, 2005)Calcium demand raises because of the change in nutrient needs, the change of weight, the level of activity the pregnant dog will incur, and the hormone levels will be fluxing which may change the bone metabolism. During lactation calcium can be detected in the mother dog’s milk.
“Plasma 1,25 (OH)(2) D(3) levels increase two-fold early in pregnancy due to high placental 1-alpha-hydroxilase activity, remain high until delivery and decline to normal values during lactation. Estrogen, prolactin and placental lactogen, which are involved in calcium absorption, increase at the same time. Normal or even low levels of parathyroid hormone (PTH) can be detected during pregnancy. This suggests that their physiological actions could be mimicked by the parathyroid- related-peptide (PTHrP), which increases in late stages of pregnancy and remain high during delivery and lactation. Calcitonin levels increase during pregnancy, decline during lactation and return to normal values after lactation  is stopped. The physiological roll of tumor necrosis factor, interleukin 6 and osteoprotegerin has not been elucidated yet. The above mentioned changes can exceptionally lead to generalized or regional osteoporosis.”  (Hakim & Zanchetta, 2005)
Normally the bone mass will recover after weaning, but in the case of hip dysplasia the damage done during the pregnancy could permanently infirm the dog.
The mother dog also presents the possibility of passing on the genetic traits that causes hip dysplasia. The tendency for this abnormal bone development affects both male and female canines equally. (Root Kustritz, 2007)Closely linked to hip dysplasia is osteoarthritis. “Two adjacent genes on the 12q chromosome, the alpha 1 chain of Type II collagen, and the vitamin D receptor, have been considered potentially related to the pathophysiology of osteoarthritis. … Significant results were found by assessing the two groups of diseases that led to hip arthroplasty, suggesting a possible link between some haplotypes and the risk of severe osteoarthritis in patients with hip dysplasia.” (Granchi, Stea, Sudanese, Toni, Baldii, & Giunti, 2002)
The puppies, if they do develop hip dysplasia, will not show signs of it until they are five to eight months old, but often once bone development settles and the joint becomes stable pain will be reduced by twelve to fourteen months old. (Lane & Ewart, 1996) It is also possible that relaxin and estrogens in the mother’s milk may have a possible link with hip joint laxity in puppies. (Steinetz, Williams, Lust, Schwabe, Büllesbach, & Goldsmith, 2008)
In a case study, “High concentrations of estrogens and relaxin were found in milk of HD+ and HD– bitches throughout lactation. Serum concentrations of milk-derived relaxin and total estrogens were similar in all pups, but estradiol-17B was detected only in pups of HD+ bitches. Hip joint laxity was reduced in pups that received CGS 16,949A. Hip joint laxity was increased in pups of HD– bitches that received estradiol cypionate and relaxin.” This case shows that hip dysplasia might be controlled or even prevented by using an antihormone treatment. This will inhibit the estradiol-17B and help reduce the onset of hip dysplasia in the newborn puppies. (Steinetz, Williams, Lust, Schwabe, Büllesbach, & Goldsmith, 2008)
The mother dog, who had moderate hip dysplasia, will suffer from the added weight on her hips due to the unborn puppies. This can be extremely debilitating to her condition and can wear away at the acetabulum wall, or the added weight could push the femur head out of the socket, causing permanent damage and complete loss of hind leg functions.
Birthing is also strenuous on the hips, and can cause similar damage to the coxofemoral joint. The articular cartilage is already of poor quality due to the hip dysplasia. Because its elasticity and thickness has been compromised, the heavy load of carrying and birthing puppies cannot be absorbed when the mother dog moves. Debris from enzymes released when the cartilage is damaged can get within the joint fluid and can damage or destroy the glycosaminoglycan and hyaluronate molecules. This prevents the cartilage from ever repairing.
Between the weight and cartilage loss, the synovial fluid in the joints will touch nerve endings in the subchondral bone. The immense pain suffered by the mother dog can be debilitating on its own. The body will attempt to repair itself with new bone, which will cause a decrease in the range of motion the dog can have. Osteoarthritis can occur down the line because of the stress induced by bearing puppies by the mother dog. (Othopedic Foundation for Animals, 2010)
The puppies, which now carry the risk of hip dysplasia, can experience an increased incidence of this abnormal bone development if they undergo a gonadectomy prior to five months of age. The link between CCL rupture and the hormonal effect it has on joint stability seems to be positive, but is still under research. (Root Kustritz, 2007)
Our mother dog, who suffered moderate hip dysplasia, could not take any medications during her pregnancy due to the risk involved with her puppies’ development. During the pregnancy she had a deficiency in calcium to make up the formation of her new puppies’ skeletons, and suffered bone loss. The fetuses grew and the added weight caused additional stress on her hips, causing cartilage breakdown, her femur head to pop from its socket, and possibly osteoarthritis. During birth her hips suffered tremendous strain, and permanent damage may have been incurred. She loss more calcium during lactation, and passed on the genetic predisposition for hip dysplasia to her puppies. The puppies will not show clinical symptoms of hip dysplasia until after a year of age, but may have an increased risk when spayed or neutered before five months old. The mother may have lost complete use of her hind legs, or severe damage.
Overall it is not recommended to allow a dog with hip dysplasia to breed.

Animal Orthopedics Paper
By: Rachel Counts
AGRON 300
11/1/11
Animal Orthopedics is a fairly new field that often mirrors the progress made in human orthopedics. It began in small animals, and has progressed to include animals all across the board including (but not limited to): llamas, horses, imus, kangaroos, and more.
There are many different types of orthopedic therapy, all meant to treat symptoms from the ill-effects of such diseases as osteoarthritis, sudden trauma, neurological disorders and more. There are many reasons as to why an animal would lose range of motion in a limb. Surgery, braces or prosthetics help animals regain use of their limbs.
Surgery is the most drastic type of orthopedics for animals, but is the most common. There are three main types of surgeries; elbow replacements, stifle replacements and hip replacements. These surgeries are normally required to replace a joint due to arthritis. The cartilage between joints wears down, and makes movement painful for an animal.
Elbow replacements involve creating a new  joint, and supporting the bone with multiple screws.  This eases the movement of that joint and prevents the rubbing of the two bones. Mobility is renewed in the animal through this surgery.
A stifle replacement is much like an elbow replacement, but if for the knee in the back leg. The surgery also differs slightly. Much like the elbow replacement, the hinge joint is replaced, but unlike the elbow replacement the new joint is supported by building down through the bone. The back legs take more brute force and need this added support to aid the joint.
Finally, the third most common orthopedic surgery is hip replacements. Hip replacements are normally necessary due to Hip Dysplasia or advanced osteoarthritis. The entire coxofemoral ball and socket joint in the femur is replaced to add stability and comfort to the hip. Animals that were once crippled due to hip problems can now move about as is normal.
The next big part of orthopedics which is often overlooked is orthopedic braces. These are meant to aid in movement through non-invasive terms. Animals that have muscle loss or neurological disorders that inhibit the range of motion in a limb can benefit from this orthopedic method. Braces support weak limbs, and use some techniques that help an animal lift limbs.
Some animals lose muscle use through sudden trauma, or sometimes merely through old age. Braces are a gentle way to regain limb use. One such case involves a dog that lost his full ability to lift his back left leg. The back of his paw dragged on the ground and wore away at the top of his foot. An orthopedic brace was assembled that attached above the stifle joint and wrapped a band around his toes. This allowed the dog to walk without injury by aiding the muscles in lifting the leg with each step.
There are several steps involved in having an orthopedic brace fashioned for an animal. First the animal is evaluated for eligibility to receive a brace. Aspects such as the extent of the injury, the deformity, the animal’s live environment, and what kind of lifestyle the animal leads is all considered before the decision can be made. Long-term goals are also reviewed to make sure the best interest of the animal is considered. Next, a cast-mold is created to make a custom-fitted brace for the animal. This can be accomplished through two different methods. Either your vet can create a cast and the dimensions can be sent in to the business creating the orthopedics, or the business can send you a casting kit for a fee. The brace will then be built over a course of five to ten days.
After the brace has been built, the orthopedic device will be tried on for the first time. Adjustments will be made to make the brace most comfortable with the largest range of motion available. Certain adjustments can be made, such as moving the frame to release pressure or to aid in support, increasing the liner to make changes to the amount of shock absorbance and to adjust friction between the animal’s limb and the device. And finally the straps used to secure the device can be changed.
Once the adjustments have been made, the animal is made a wearing schedule to help “break in” the device. Animals must accumulate to the device to be able to wear it comfortably. The orthopedic brace is not intended to by worn all the time.   
After the device has been made, repairs and refurbishments are often offered through a business to keep the device in working order. Two aspects of the brace can be repaired or refurbished: the frame, or the foam lining/straps in the brace.
The last big part of orthopedics is prosthetics. Animals will lose their feet in traumatic events, such as an accident or through hypothermia. One such animal was a cat that urinated in the freezing weather, and became frozen to the ground from the liquid on her back legs. She lost both back feet, but was able to be fitted with prosthetic paws.
Prosthetics are built in much the same way as a brace. A mold can be taken of an existing leg or foot or of the injured leg to help determine the placement of the new limb. The animal is then sent into surgery where the prosthetic is grafted into the bone. The bottom part can be attached from outside the animal to be able to have repairs, or it can be a permanent replacement.
Prosthetics are still an expanding field, and requires a lot of research to be taken to new places, just as human prosthetics are. But prosthetics for now are an amazing field that can be very extensive. Some animals have had as many as all four feet replaced. This helps us see how far we’ve gone in this narrow field already.
Orthopedics in general help animals lead better and more natural lives. It’s still a developing field, but we’ve come a far way since working on exclusively small domestic animals. Surgeries, braces and prosthetics are all equally important in the field, and each deserves its own respect.

11/1/11

Animal Orthopedics is a fairly new field that often mirrors the progress made in human orthopedics. It began in small animals, and has progressed to include animals all across the board including (but not limited to): llamas, horses, imus, kangaroos, and more.
·         Joint Athroplasty:
o   Elbow Replacements: requires supporting bones and reconstructing joints
o   Stifle Replacements:  create a new hinge joint. Supported by building new joint into bones
o   Hip Replacements: normally required because of hip dysplasia. Replaces coxofemoral
Short video
·         Orthopedic Braces
o   Helps support weak limbs or other degenerative diseases
o   Process includes: Evaluation for eligibility to receive brace. Mold brace to animal. Build brace. Try on new orthopedic brace and make final adjustments. Refurbish or repair brace over time.
·         Prosthetics
o   Normally meant to replace missing feet/paws or limbs.
o   Expanding field
o   Lots of progress
o   Some animals have had as many as all limbs replaced


Breed Banning: Dogmatism against Dogs

This was written for an English 201 class concerning the uprising of the bans on certain dog breeds. It's an opinion and argument paper.

Breed Banning:
 Dogmatism against Dogs
The history of the dog spans alongside human history, and dogs have served man since the first wolves wondered with our nomads. Their undying loyalty to man has provided means to our protection, food, transportation and some daring rescues. Centuries of humankind molding dogs to perform specific duties for our benefit have allowed our kind to flourish, and in return our companions asked for nothing more than scrap meat.
Canis lupus famaliaris, otherwise known as today’s domesticated dog, has worked alongside man for as long as our history is written. But until recent years their part in our society was ignored or at best a side note. We developed laws to protect what had aided us through the ages, yet these laws are yet to be complete.
Creatures of habit, we have continued to ignore our pets. But this time we have not forgotten their important roles in our society, but rather we have forgotten their past. Dogs were bred to guard our possessions, they were bred to hunt living creatures, and they were bred to work. In 2007 almost half of pet owners considered their pet to be a part of their family. (American Veterinary Medical Association, 2007) Our family members do not sit outside to protect the home, they do not dig into rabbit holes to catch a rabbit with their teeth, and they do not pull sleds in teams. Yet these were exactly the types of activities ingrained into our dog’s genetic code, and by treating them like a part of the family, we’ve taken away their work.
And for those dogs that are not a part of the family, they are often chained or enclosed all day, every day, and every year. Dogs Deserve Better, a dog rights group, had this to say on chaining dogs:
Experts agree that chaining increases aggression in some dogs.Rather than protecting the owner or property, a chained dog is often fearful for itself, particularly poorly socialized dogs or those with a previous negative experience," says Rolan Tripp, affiliate professor of animal behavior at the College of Veterinary Medicine at Colorado State University.
“When tethered and exposed to a potentially threatening stimulus, one thing the dog definitely knows is, `I can't get away.' In that circumstance, a reasonable response might be, `Therefore I'm going to try and scare you away by growling or, worse yet, biting.'” (Becker)
We wonder why our pets or our chained dogs are aggressively lashing out at by passers, all the while a sort of ignorance towards what that dog’s purpose once was. Their teeth are not for looks; the dog descended from the mighty wolf – predator and pack member.
But does this mean the dog is not suited for the life of a family pet? We have a long history of living side by side with this animal, and have the means to understand their psychology better than almost any other animal because of our better understanding of how the mind works today. With these tools we can learn about and understand our beloved pets. We’ve all known or heard of the “perfect dog”. Never growled, was friendly with all, stayed off the couches and was full of personality. What we need to know is how to have the perfect dog.
To understand our dogs, we must understand our current methods have been ineffective. In countries all across the world certain dog breeds are being banned. The famous Cesar Millan, world renowned “Dog Whisperer” and behaviorist, coined the phrase “powerful breeds”. (Millan, 2008) When referring to the powerful breed, the common dogs that come to mind are Pit Bulls, German Shepherd, Rottweilers, Dobermans, and more. These dogs have a frequent history of being aggressive, and so have been banned from places around the world.
Pit Bulls were bred often to be herders (United Kennel Club, 2008), and the Doberman Pinscher was bred in Germany to be a guard dog. (United Kennel Club, 2003) These characteristics are common in powerful breeds, and unfortunately our ignorance of this has led to bored or aggressive dogs. The working class of dogs are only truly happy when actually working, and our want for a lazy dog to lay about the carpet or to simply bark when a visitor appears has stripped away the true purpose and drive of the dog.
William Twitchell, the Advanced Animal Handling and Behavior professor at Brigham Young University – Idaho, had this to say:
“[Dogs must be] taught how to interact with humans, taught how not to be aggressive towards humans… If you go through and teach a dog specific commands, and the dog obeys those commands, then the dog recognizes you as more of an alpha and therefore recognizes to be respectful.” (Twitchell, 2010)
This sort of understanding of dog psychology can lead to balanced and submissive dogs, regardless of breed. Dogs bred for working purposes have a strong disposition for certain activities, but can be trained to be regulated and controlled.
An important part of a dog’s development is socialization. Learning what social cues mean at a young age, and how to appropriately behave in situations can prevent aggression in an adult canine. Dogs that are bred commonly for guard duty will not act aggressive towards those that are accepted by the owner, and will learn to differentiate between a threatening human and an innocent human. A dog will also gain confidence with this socialization, and be less fearful, and thus will reduce fear-induced aggression.
According to the book, The Dog, Its Behavior, Nutrition and Health, dogs will react to fear in three different ways. There is flight: moving away from the object of fear; freeze: not moving; and fight: becoming aggressive towards the cause of fright. (Clark, 2005, p. 166) Aggression has frequent root causes, such as dominance, territorial or protective, possessive and other types of aggression. (Clark, 2005, pp. 171-172) However, “no specific gene or even set of genes has been found that cause aggressive behavior, predatory instinct, or any other type of species-specific behavior pattern. (Coppinger, 1996, pp. 9-18) This gives us valuable insight into the causes of aggression in dogs. Breed - or more specifically, genes - are not responsible for dog attacks on the public. It is conclusive to say that environment is the major factor for dog attacks.
The biggest influence on a [r]ottweiler's behaviour was its environment,” as declared by Ian McLean, president of the Queensland Rottweiler Association. "There's a lot of rubbish spoken about rottweilers. They're not born aggressive, but they are stubborn and headstrong," he said. (One India Living, 2008)
Even Professor Kerry Powell, the genetics professor at Brigham Young University – Idaho, agrees that aggression is not found in the genetic make-up of animals. “Their fight or flight responses are genetically influenced, and even a predisposition for temperament, but aggression is not specifically found in genes.” (Powell, 2010) Powerful breeds are powerful because they were bred to be able to do strenuous work, whether it is a bulldog bred to bite and hold on to a bull, a husky bred to pull a sled, or a Doberman bred to snap at anyone invading its territory – these dogs have strong predispositions to do their work. And banning a dog for doing its work is not the answer to dog aggression.
Cesar Millan has introduced to the public correct handling skills for powerful breeds through his television show, Dog Whisperer, and his many books. One of the main outlets for pent up energy in a dog is appropriate exercise. Swimming, running, long walks and other forms of strenuous exercise for a dog will create a tremendous difference in a dog’s temperament. Energy that was once expressed as aggression is drained, and the dog learns his place in the “pack” by travelling with his owner when walked correctly. This is done by establishing that the dog may never lead the walk, or pull on the lead. (Millan, 2008) The Dog Encyclopedia states, “People who keep German Shepherds frequently overlook the fact that they are eager to work for their handler… If you do not have the time to devote to it, do not purchase a German Shepherd.” (Verhoef-Verhallen, 1996, p. 30) This is true of any powerful breed.
Breed Ban Legislation is the practice of banning an entire breed from specific areas. And unfortunately the Pit Bull is a news favorite. But the difficulty comes when legislators attempt to define the word “pit bull”, which is no more a breed than a “hound”. This wide range of dogs that fall under this category makes it more likely that a “pit bull” will bite, because it involves several different breeds of dogs.
“It has been estimated that there are half a million pit bull terriers alive in the United States today. What about the 99% who have never bitten a human being? Are these dogs "loaded handguns," as many have called them? "There's something a little scary about wondering, Is there a time bomb ticking in my dog?" says Dr. Franklin Loew, dean of Tufts Veterinary School, who opposes efforts to legislate against pit bull terriers and believes the breed is the victim of "canine racism." Loew adds, "The pit bull does seem to respond more than other dogs to people trying to bring out aggressiveness. But everything I know professionally tells me that this is not a dog problem, but a problem of dog ownership." (Swift, 1987)
Banning a breed does not fix the problem of bad dog ownership, in fact it displaces blame. It’s easier to blame the dog than to accept that you haven’t raised your dog right, and even easier to turn a dog out and say you just didn’t have the time to train him. Owning a powerful breed means more responsibility than other breeds and you owe it to the dog to give it proper exercise, discipline and affection (and as Cesar says, “In that order”.) (Millan, 2008)
But perhaps blame lies with the common misconception that anyone can own any dog they please. It’s not unusual for a dog to be chosen for looks - or as a status symbol - and for that dog’s needs to be neglected. Certain breeds are more aptly made for specific kinds of work and when that energy is never drained the dog becomes frustrated, hyperactive, and even aggressive.
Dogs 101, a popular television show on Animal Planet, always has the disclaimer during the credits: “Remember, each dog is an individual and will not always conform to breed standards.” ( Discovery Communications, 2010) So then why is it our reaction to treat an entire breed as a singular unit, and assume a dog attack means all dogs of that breed are vicious? William Twitchell stated, “I have a mutt more dangerous than any pit bull.” (Twitchell, 2010) Yet mixed breed dogs are well known for their sweet nature and healthy body condition, generally. So does this mean that Willy Twitchell’s mixed breed dog should be a model for all mixed breeds? It is obvious that Twitchell’s “dangerous mutt” is its own individual, and so a dangerous pit bull should be regarded in the same manner. It is a hazardous dog - not a hazardous breed.
Some will argue, such as Dr. Loew, that many breeds are a victim of “Canine Racism”, yet we know that some breeds have been bred specifically to bite or kill animals. When this attitude is turned on humans, we are shocked and horrified. But should we be? We created these animals, and now we discriminate against them for doing exactly what they were bred to do. Our downfall was we stopped giving our dogs a focus, or target, to direct this behavior. We chain them up, or never train them, and expect them to be well-behaved naturally. But just like raising a child, a good dog does not just happen
In fact, dogs that are chained are 2.8 times more likely to bite than an unchained dog. (DogsBite.org, 1991) Dogs Deserve Better, an organization working for a more humane lifestyle for dogs, spent 54 days on the steps of congress protesting the lack of laws that allow pet owners to chain their dogs all day, every day, and every year. This leads to dog aggression, they say. (Dogs Deserve Better, 2010)
Even more interesting is the American Temperament Test Society found that the American Pit Bull Terrier, and American Staffordshire Terrier (most commonly recognized breeds in the pit bull group) are in the 83rd percentile, which means that 80+% of the these dogs passed the temperament test, which grades dogs based on “stability, shyness, aggressiveness, and friendliness as well as the dog's instinct for protectiveness towards its handler and/or self-preservation in the face of a threat.” (American Temperament Test Society, Inc. , 2010)
.  Other breeds, such as the Bichon Frise (76.7%), Chihuahua (71.1%), Shih Tzu (78%), and the Shetland Sheepdog (68%) are comparatively well below the pit bull, which is shocking considering these are common family pets. (American Temperament Test Society, Inc. , 2010)
Another common cause of dog aggression towards humans is our inability to communicate with the dog our intentions. People often approach a fearful or aggressive dog that has been giving warnings to stay away without knowledge of these messages the dog has been sending. Reading a dog’s body language is the key to communication with dogs, and lack of knowledge in this can lead to dangerous situations.
Many factors lead up to dog aggression including, but not limited to: lack of exercise or discipline, ignorance to that breed’s specific needs, or ignorance of appropriate social behavior. Dogs that were bred for working purposes need more exercise and discipline than smaller or more docile breeds. Breeds that were intended for biting or attacking other animals have more powerful jaws and heavier builds to bring down prey, and this dangerous mixture has not been taken seriously by uninformed dog owners.
Banning dog breeds is not the answer. But special registration or required training of powerful breeds may be. If a well informed pet owner with previous dog experience understands the risks and needs of a powerful breed, they will be better prepared for training their dog to be behaved socially. By asking potential adopters or buyers their dog experience, or requiring basic training courses for owners of powerful breeds, we will be ensuring people are better equipped to handle their dog correctly and prevent aggression.
A dog that is aggressive is not balanced, and we are failing as owners to provide our dog’s needs. Until we can come to understand how our canine friends are thinking as a collective, dogs will continue to suffer because of our lack of knowledge.
We need to take greater steps in understanding our pets who have served us so faithfully throughout the years. It is the least we could give them. Dog breeds are not dangerous – human ignorance is.
