Masticatory Myositis in Dogs

Masticary myositis is a veterinary medical condition that affects dog. The condition causes the muscles that the dog uses for chewing to become inflamed, reports Michigan Veterinary Specialists.

  1. Types

    • There are two main types of masticary myositis: acute and chronic. The acute form comes on quickly and responds rapidly to treatment, while the chronic form has a tendency to linger on or disappear only to reappear again.

    Symptoms

    • The most common symptoms of acute masticary myositis is excessive drooling and a loss of appetite or lack of interest in eating. Chronic masticary myositis usually occurs after repeated bouts of the acute form of the condition, with its most noticeable symptom being a sunken-in appearance of the dog's cheeks accompanied by difficulty opening their mouths.

    Causes

    • Veterinarians do not fully understand the causes of masticary mysotisis, but believe it is tied to the immune system.

    Prevalence

    • Masticary myositis affects all breeds of dogs, but is most common in large dogs, such as German Shepherds and Golden Retrievers. The condition affects young or middle-aged dogs.

    Diagnosis

    • Veterinarians typically diagnose masticary myositis through physical examination as well as blood work and electromyography or EMG to rule out other possible causes of symptoms.

    Treatment

    • To treat masticary myositis, veterinarians typically prescribe oral corticosteroid medications.
