Muscular Dystrophy is an inherited, progressive, and non-inflammatory degenerative muscular disease caused by a deficiency of dystrophyin, a muscle-membrane protein. This generalized muscle disorder is primarily seen in newborn dogs or those less than one year old. Male dogs are also more susceptible than females, as are golden retrievers, Irish terriers, Pembroke Welsh corgis, Samoyeds, rottweilers, Belgian shepherds, rat terriers, Brittany spaniels, Labrador retriever, German short-haired pointers, and miniature schnauzers -- all of which often suffer from dystrophin deficiency.

You will need to give a thorough history of your dog’s health, including the onset and nature of the symptoms, to your veterinarian. He or she will then conduct a complete physical examination as well as a biochemistry profile, urinalysis, and complete blood count (CBC). Creatine kinase enzyme levels may be elevated due to the dystrophin deficiency. Liver enzymes are also elevated in dogs with this disorder.
The most hopeful test for reaching a definitive diagnosis, however, involves taking a muscle biopsy. The muscle tissue sample is sent to a veterinary pathologist to verify abnormal levels of dystrophin.
No treatment is proven to be effective. Glucocorticosteriods are often given to dogs suffering from non-inflammatory muscular dystrophy, but their effectiveness is variable and their exact mode of action in this disease is still unknown.
Dogs with this disorder are prone to aspiration pneumonia or cardiac disease and must evaluated at regular intervals for such complications. Be vigilant of complications and contact your veterinarian should problems arise. However, symptoms may stabilize after six months in Golden retrievers.
Unfortunately, the overall prognosis is very poor in dogs with non-inflammatory muscular dystrophy. Often, your veterinarian will discourage breeding the animal, due to the genetic nature of the disorder.
