Definition of Lupus
Lupus is a general term for an autoimmune disease characterized by the formation of antibodies against the body’s own tissues. There are two different forms of lupus in dogs, and they have different symptoms and effects.
How Lupus Affects Dogs
Discoid lupus erythematosus (DLE) is an autoimmune disorder that causes depigmentation, redness, scaling, erosions, ulcerations and crusting on the nose, face and lips of dogs. Most dogs with this form of the disease have skin problems on their nose which develop into sores and peeling.
Systemic lupus erythematosus (SLE) is a much more serious form of lupus in which the body’s immune system attacks multiple areas of the body. While a number of clinical signs may occur, the most common include arthritis, anemia and skin diseases, all usually accompanied by pain.
Causes of Lupus in Dogs
The causes of lupus are still unknown, although a genetic predisposition is thought to be likely.
Preventing Lupus in Dogs
There is no known way to prevent this condition in dogs, other than not breeding affected animals.
Special Notes
Systemic lupus erythematosus has a guarded prognosis. Discoid lupus erythematosus has a good prognosis.
