Prevention Is Smart Breeding- Ataxia and the American Staffordshire Terrier

With a beautiful variety of coat colors and markings in combination with their impressive muscular build, the striking appearance of the American Staffordshire terrier (AST) is one to behold. The modern AST can trace its origins to 19th century England when bulldogs of the time were bred to terriers in an attempt to create a dog with the most desirable personality traits of each breed (the specific breed of terrier used in the early breedings is in dispute among domestic dog historians and may have actually been multiple terrier breeds).

As the AST has progressed as a breed, so has the understanding of the genetics that underlies the breed we see today. In addition, the discovery of particular genetic mutations responsible for causing inherited diseases has allowed for the development of genetic tests to identify nonsymptomatic carriers and young dogs affected with late-onset inherited disorders. Through the genetic knowledge gained ...
