What is masticatory myositis?
• Masticatory myositis is an inflammatory disorder that involves (primarily or exclusively) the muscles of mastication (chewing). The actual cause of masticatory myositis is unknown, but is suspected to be an immune-mediated mechanism. This disorder can affect any dogs of any breed, but it seems to be seen most commonly in German Shepherds, retrieving breeds and other large breed dogs. It is seen most commonly in young or middle-aged animals and there is no gender predisposition. This has not been recognized in cats.
