What causes a dog to get lupus? Causes of lupus in dogs include genetic factors, immunologic disorders, and environmental factors. Environmental factors such as ultraviolet light and cigarette smoke trigger or worsen DLE. Stress may also worsen lupus. Some dog breeds are more prone to getting the disease.
Is lupus in dogs contagious to humans? There are two main types of lupus seen in dogs—systemic lupus erythematosus and the less challenging discoid lupus erythematosus (DLE). Other species, including humans, can also develop lupus, but it is not contagious.
How do you test a dog for lupus? The diagnosis of DLE requires a skin biopsy. Your veterinarian will obtain a small sample from a skin lesion using an instrument called a punch biopsy.
