This condition is one of inflammation (itis) of the skin (dermato) and muscle (myo) that is seen in young collies and Shetland sheepdogs. There appears to be a defect in the immune system that predisposes dogs to this disorder. The skin lesions typically develop first with variable muscle problems occurring later. There are many similarities to dermatomyositis in people. Ulcerative dermatosis may be a variant of this condition. It is a rare disorder that occurs in middle-aged to older dogs of the same breeds, and is manifest by skin lesions (blisters, crusting) that are seen primarily in the groin and underarm regions. Occasionally there are muscle abnormalities.
