The purpose of this paper is to discuss the trend of increased health problems in the modern canine being caused by inappropriate breeding practices.

Definition of Terms:

COI- Shows the relationship between two purebreds found by the formula:

Fx = Sum[(½)n1 + n2 + 1(1 + FA)] (“About Inbreeding”).

Dystocia- Painful and troubled labor (“Dystocia Definition”).

Elbow Dysplasia (ED)- Painful disorder in the elbow joint caused by improper bone growth (Maki).

Exophtalmosis- A condition in which the eye comes out of the socket (“Exothalmos”).

Hip Dysplasia (HD)- A loosely fitting hip joint, over time weakening the hip bone as a result of insufficient weight bearing (Maki).

Introduction

Over the latter part of human history, man-kind has had a dramatic effect on the canine genome, using inappropriate breeding practices to achieve great changes in physical appearance while negatively impacting canine health (Arman). Because pedigree standards instituted by kennel clubs historically focused on appearance rather than behavioral or internal health, many breeders today incorporate breeding practices such as inbreeding and line-breeding to achieve an ideal pedigree (Maki). However, these breeding practices produce negative results by increasing the frequency of genetic disorders and decreasing the size of gene pools (“Animal Welfare”). Sensory, joint, and heart disorders have now become a mainstay amongst dog breeds (Bjornerfeldt). Because many breeds have characteristics that are in themselves unnatural and unhealthy for the individual dog, veterinarians must intervene to maintain decent health. Every generation these characteristics become more deeply in coded in the canine genome, perpetuating significant complications in ...

  • EhlersDanlos Syndrome

    1021 Words  | 3 Pages

    There are approximately six types of EDS that have been distinguished but other types exist that are very uncommon. Classical, Hypermobile, Vascular, Kyphoscoliosis, Arthrochalasia, and Dermatosparaxis. Classical and Hypermobile make up over 90% of all reported cases of EDS. With the Classical type of EDS a person would have hyperextensible (stretchy) skin with widened atrophic scars and joint hypermobility. The skin is smooth and velvety with tissue fragility and easy brusability. Also evident are molluscoid pseudotumors (fleshy lesions associated with scars) frequently found over pressure points (e.g. elbows) and subcutaneous spheroids, which are commonly mobile and palpable on the forearms and shins. Complications of joint hypemobility include sprains, dislocation are common in the shoulder, patella and temporomandibular joints Muscle hypotonia and slower gross motor development also can occur It is inherited in an autosomal dominant manner (Clarke, D., Skrocki-Czerpak, K., Neumann-Potash, L.).

    Consequently, the dog we see fitting the classic mold outline in the American Kennel Club (AKC) Boxer breed standard is a bit different from the portrait we would see if the pup were allowed to grow up without surgical intervention. These procedures lie at the heart of a rather heated debate, especially in the Boxer world. Unlike many other cropped and docked breeds, the Boxer’s breed standard offers no choice regarding whether the tail or, most significantly, the ears may be left natural and still satisfy the

  • Puppymills Vs Shelters

    2358 Words  | 5 Pages

    Hundreds of thousands of puppies are raised each year in commercial kennels (Puppymills Breed Misery). Puppy mills keep breed stock in horrible conditions for their short lives and produce unhealthy puppies with many issues. Not only are they committing “inhumane care,” but puppy mills are responsible for customer fraud. Many puppy mills are small and contain about twenty breeding dogs in basements, garages, or sheds “in cages stacked to the roof.” The dogs will stay in those cages without “exercise or sunlight.” Also, the dogs have two “litters” a year till about the age five. Other puppy mills contain hundreds of breeding dogs. The operators keep the puppies in “relative darkness” so the puppies seldom cry or draw attention. The dogs in puppy mills rarely receive medical attention. The females are dissipated because of the never-ending period of “producing and nursing litters.” Most dogs have “chronic ailments, rotten teeth, and ear, eye, and skin infections.” Many of the puppies purchased from puppy mills are un-healthy and not well-adjusted. The puppies have a high prevalence of hereditary syndromes and illnesses, and difficulties that occurs following the “purchase.” After the females cannot produce anymore liters...

  • The Pros And Cons Of Puppy Mills

    With the holidays approaching, many young couples are looking into getting their better half a puppy for Christmas. But what they do not know is that the puppy could have been bred in one of the most inhumane ways. Puppy mills are all over the United States, and the government has turned their cheeks to the horrors behind those barn doors. Dogs are put in small crates, often filled with their own feces. Pups are not bathed regularly with no veterinary attention, so this often leads to infection, and they are bred at every opportunity with little to no recovery time in between.

  • Breed Specific Legislation Essay

    601 Words  | 2 Pages

    Every year an estimated 4.5 million dog bites occur in the U.S. BSL (Breed Specific Legislation) is a law that suggests that certain breeds are more prone to aggression than others. By banning or restricting the breeds in question, it is believed to help reduce the number of attacks. BSL determines which breeds are dangerous using statistics. These statistics cannot be relied on for two reasons. One, there is no concrete method to determine a dog’s pedigree. Thus, a victim, animal control officer, or owner is trusted with identifying the dog through appearance. According to Scott and Fuller, authors of Genetics and the Social Behavior of the Dog, “It has been known for decades that the cross-bred offspring of purebred dogs of different breeds often bear little or no resemblance to either their sires or dams (1965).” Visual assessments are questionable. Two, population is not accounted for. Population is important, in that it provides context to percentages. Because a dog’s breed is impossible to pinpoint, we cannot provide numbers. BSL’s cause is rendered useless when we consider these points.

Science also helps us to achieve the task by continuously consulting with paleontologists to research the skeletal structure of dogs and compare the existing bone and body structure to previous breeds. In this regard, Associations have established strict rules and regulations for breeding as well as created a way to unify all breeders in a wide-ranging system in order to promote healthfulness and reward breeders who consistently produce specifically heavier, taller and with longer life span puppies for this purpose by adopting crossbred lines and standardized breeding practice

  • Do dogs resemble their owners

    535 Words  | 2 Pages

    People have started to make remarks of the resemblance between dogs and their owners, and from what we have found, it is usually noticed at dog shows and from strangers passing by in the streets. There are two factors that could make the owner and the dog similar. One would be people selecting dogs that are like them, and people who select dogs which features start to change and become similar to them over time. As a comparison to animals and their dogs, there is evidence that couples look physically similar after 25 years rather than people who have recently been wed. In the research we have conducted, we have found that purebred dogs have a greater resemblance than people who own non purebred dogs.
