Title

Disease Prevalence: Pedigree Pups Versus Mutts

Abstract

The domestic dog, Canis familiaris, is the most morphologically diverse mammalian species. The drastically different phenotypes of dogs result from slight variations between genotypes. Selective artificial breeding encouraged by the American Kennel Club has maintained standards for conformation of the 189 currently recognized purebred dog breeds. Recently the AKC has been criticized for enforcing breed standards because each of the 50 most popular breeds is predisposed to at least one inherited disorder, many of which are directly related to conformation. To assess this phenomenon locally, I conducted an observational study using data from Animal Clinic East in Walla Walla. Medical records of over 900 dogs were evaluated and categorized for eight common breeds and eight common diseases (hip dysplasia, diabetes, etc.). Distinct correlations were found between specific pedigree breeds and associated diseases. A review of the literature corroborated the local study results.
