* Ataxia (NCL-A) Cerebellar Ataxia of American Staffordshire Terrier is a severe neurological disease. This disease is hereditary and can be prevented. There is a DNA test for Cerebellar Ataxia in the American Staffordshire Terrier which consists of a simple cheek swab. The first signs of the disease usually appear between 3 and 5 years of age in affected dogs. They are: loss of balance, difficulty cornering, and falling when shaking their head. As the signs progress most dogs have difficulty with movement. When they become unable to walk without falling most owners make the difficult decision to euthanize. Test results will determine if a dog is Ataxia Clear, Carrier or Affected. The breeding of two affected dogs will result in the disease. The breeding of a Clear to a Carrier will result in 50% of the puppies being Clear and 50% Carriers, testing of the litter would then be required. The breeding of two carrier dogs creates the potential for all affected puppies.
