Dystrophy-like muscular diseases may begin to show their presence in the first weeks to first months of a dog’s life. Muscle atrophy is a distinct sign of the affliction, leading to further complications. Progression will vary from dog to dog, and studies to date have stated that this condition tends to affect male dogs predominantly.

The symptoms of two types of inherited muscle disease are listed below. If your furry family member is exhibiting any of these concerning behaviors, contact your veterinarian for testing and advice.

Some of the other hereditary muscle diseases found in dogs are congenital myotonia (Chow Chows and Staffordshire Terriers are prone), and sarcoglycan deficiency (Cocker Spaniels, Chihuahuas, and Boston Terriers are predisposed).

Inherited muscle diseases are due to genetic and hereditary factors, as these examples show.

The diagnosis of muscular dystrophy in your pet will be an extensive process. Your veterinarian will want to rule out a differential diagnosis that could cause some of the same symptoms. For example, peripheral nerve neoplasia (abnormal cell growth), arthritis, metabolic or systemic disease, and respiratory insufficiency could all have symptoms that mimic muscle degeneration.

The visit with the veterinarian will commence with a few questions.

After a physical and neurological examination, your veterinarian will look for further diagnostic information in the form of a complete blood count, biochemistry, and urinalysis. The serum creatine kinase and enzyme levels seen can be particularly telling when searching for answers to muscular dystrophy.

A muscle biopsy could be suggested, which will reveal variations in muscle size, and degree of atrophy. A electromyography can assess the general health of the muscle. DNA tests can prove certain mutations known to be evident in hereditary muscle disease.

Unfortunately, there are no known cures or treatments for non-inflammatory hereditary muscle disease. Minimal drug therapy is available; for instance, the use of glucocorticosteroids is sometimes attempted in the case of dystrophin deficient myopathy, but in reality, the disease is progressive.

Eventually, many dogs will face debilitation, and some will have heart muscle disease. However, it should be noted that the progression will vary in each dog diagnosed with muscular atrophy. Some will face a rapid degeneration of muscle, while others will remain healthy and relatively active for some time.

Physiotherapy and supportive measures on your part (like providing soft bedding and regular, gentle exercise), can help pets who have this condition. There is a positive outlook for our canine friends who have been diagnosed with Labrador Retriever myopathy; this condition can stabilize once the dog reaches maturity.

Because the majority of family pets who are given this diagnosis are young, we must remember that many of these dogs, despite the illness, can lead good lives until their condition becomes a hindrance to their quality of life. Your veterinarian is the best person to ask for advice; she will honestly and thoughtfully provide you with the information you need as you learn more about hereditary muscle disease and what it means for your dog.
