Generalized Inflammatory Muscle Diseases in Dogs



Corticosteroids are typically used to suppress an overactive active immune system, which may be an underlying factor. In addition, antibiotics are prescribed to fight off infection. Long-term corticosteroids treatment may be required in dogs with severe immune-mediate diseases.


Living and Management


As muscle inflammation decreases, you will need to increase your pet's activity level to improve muscle strength. Dogs with an enlarged esophagus (megaesophagus) will require special feeding techniques. You will briefed about elevating feeding and adding various foods to the dog's diet, especially foods of different consistencies. In cases of severe regurgitation, your veterinarian will place a feeding tube into the dog's stomach to ensure proper nutrition. He or she will also show you how to use the feeding tube correctly, and will assist in setting up a feeding schedule. In addition, good supportive care is required to prevent skin wounds and ulcers in non-emergency patients.


Fortunately, dogs with polymositis and dermatomyositis due to immune-mediated causes have a good prognosis. If cancer is the underlying cause of the diseases, however, prognosis is poor.
