Dermatomyositis in Shetland Sheepdogs

Moderate Risk
Category: Dermatological Typical onset: Under 6 months Hereditary: Yes Est. treatment cost: £400-£2,000/year

Dermatomyositis can affect members of the breed within the Shetland Sheepdog. Common indicators include skin lesions on face, ears, and legs, muscle wasting, especially of masseters, and difficulty eating in severe cases. Dermatomyositis is an inherited inflammatory condition affecting the skin and muscles. It begins with skin lesions on pressure points and the face in young dogs and can progress to generalised skin disease and muscle atrophy causing difficulty eating and walking. It typically becomes apparent at Under 6 months. In smaller breeds like the Shetland Sheepdog, early detection and prompt treatment generally lead to better long-term outcomes. This condition has a hereditary component — prospective owners should request documentation of health screening from the breeder. Treatment costs are estimated at £400-£2,000/year, making comprehensive pet insurance a practical consideration.
