Systemic Lupus Erythematosus (SLE) in Dogs

High Risk Autoimmune

Systemic Lupus Erythematosus (SLE) is a high-severity autoimmune condition that can affect dogs of all ages and breeds. SLE is a complex immune-mediated disease characterised by autoantibody production against multiple tissues, causing a wide variety of signs including polyarthritis, skin lesions, haematological abnormalities, and kidney disease. It is documented across 5 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at 2-8 years. Early signs to watch for include shifting lameness (polyarthritis), skin ulceration and hair loss, fever, and anaemia. When treatment is required, costs are estimated at £2,000-£6,000/year depending on severity, location, and the specific intervention needed. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
