Genetic testing is important for any breed, for the dog’s individual health and wellbeing as well as for any breeding dogs to ensure healthy puppies in future generations. Paw Print Genetics offers genetic testing for three diseases known to occur in the Alaskan Malamute. Testing for these diseases provides you the information that you need to keep your dog healthy and to select appropriate breeding pairs to avoid producing affected puppies.

The first disease is the Alaskan Malamute Polyneuropathy. This disease is an inherited neuromuscular condition that affects dogs between the ages of 3 and 19 months of age. The first signs of this disease may be a change in their bark, noisy breathing, exercise intolerance and loss of hindlimb coordination. The disease is progressive resulting in muscle wasting, abnormal gait or inability to walk. Testing of this disease is required for CHIC and using results in your breeding program can eliminate producing affected pups.  This disease is inherited in a recessive manner meaning that two copies of the mutation are required to produce the symptoms of polyneuropathy. Dogs that have one copy of the mutation are carriers and are not affected. Breeding carriers to clear (normal) dogs will ...

Degenerative myelopathy (DM) can be a devastating disease. Some breeds with this disease will lose the ability to walk in their later years – certainly after the age most dogs are bred. The mutation has been found in more than 120 breeds (1), which indicates that the original mutation might have occurred hundreds or thousands of years before many of the modern dog breeds emerged.

However, the frequency of the mutation varies between breeds and certainly the risk of developing the clinical disease seems quite distinct and breed-specific. For example, the frequency of carriers and homozygous mutation (affected) dogs in the Kerry blue terrier is about 52%(1), while carriers and affected dogs make up 91% of Pembroke Welsh corgis in Japan(2). Although wire fox terriers have a similar combined carrier and at-risk frequency of 90%, none have ever developed the clinical signs of DM(3).

In a 2001 study by Moore et al., German shepherd dogs had nearly twice the risk for death associated with spinal cord diseases, compared with Belgian shepherd dogs among military dogs(4).  Although we don’t know for sure if the spinal cord disease was DM, certainly DM is one of the more common causes of this ...
