Can dogs recover MMM?
If MMM is diagnosed early and treatment is initiated right away, a dog usually regains normal jaw function and the ability to open and close his mouth without pain. In some dogs, scar tissue can form within the masticatory muscles causing permanent problems.
Can a dog regain muscle mass?
How to Fix It. When muscle atrophy in dogs is caused by inactivity, it is often possible the reverse the muscle loss with exercise and adequate nutrition. As dogs get older, their nutritional needs may change.
Is MMM fatal in dogs?
“If the disease is diagnosed early and a dog is treated appropriately, the prognosis is good for dogs with MMM,” Greenfield says. “In these cases, dogs can usually regain normal jaw mobility and function.
How serious is MMM in dogs?
Dogs in the acute phase of MMM have swollen, painful jaw muscles and trismus, or the inability to open the jaw. Clinical signs vary in severity and rate of onset. Ocular signs occur in 44 percent of dogs and, if severe, can result in stretching of the optic nerve and subsequent blindness.
What happens when a dog loses muscle mass?
Although all dogs do tend to become more lethargic with age, muscle loss can visibly heighten this phenomenon. Having less muscle makes it much harder for your dog to move around freely, and can also cause pain in joints and muscles as a result of movement.
What does it mean when a dog has masticatory myositis?
Masticatory muscle myositis (MMM) is an immune system disorder in which the dog’s immune system identifies the dog’s own muscle tissue as foreign and attacks it. The masticatory muscles are the muscles involved with chewing. MMM causes these muscles to become swollen and painful.
Are there false negatives for masticatory muscle disease?
We have not yet detected antibodies against type 2M fibers in denervating disorders or other neuromuscular diseases. False negatives may occur if the dog has been on immunosuppressive dosages of corticosteroids for longer than 7-10 days or if the MMM is end-stage with destruction of type 2M fibers and marked fibrosis.
What do you need to know about masticatory muscle?
The 2M antibody assay will provide the diagnosis (in the absence of corticosteroid therapy or end-stage disease) but does not provide information about degree of myofiber destruction or fibrosis which are important in determining a prognosis. The owner will want to know about return of jaw function and muscle mass.
What to do if your dog has muscle myositis?
Immunosuppressive drugs and corticosteroids are usually administered to manage this condition. MMM causes inflammation of the muscles and can cause scar tissue to form in the muscles, hampering their function.

Do you need a blood test for masticatory myositis?
The blood test must be done before any treatment is provided, as treating with corticosteroid anti-inflammatory medication may cause the blood test to register a false negative. In cases where circulating autoantibodies are not detected, there is another diagnostic test for MMM, a muscle biopsy.
Immunosuppressive drugs and corticosteroids are usually administered to manage this condition. MMM causes inflammation of the muscles and can cause scar tissue to form in the muscles, hampering their function.
How long does masticatory muscle myositis therapy last?
“At that time, the dosage can be tapered to the lowest every-other-day dosage that prevents clinical signs. Once the lowest alternate dosage is reached that keeps the dog free of clinical signs, the alternate-day therapy should be continued for at least four to six months.
