Legg-Calvé-Perthes Disease in Dogs
Legg-Calvé-Perthes Disease is a high-severity orthopedic condition that can affect dogs of all ages and breeds. Legg-Calvé-Perthes is an avascular necrosis of the femoral head in small and toy breeds. The blood supply to the femoral head is disrupted, causing the bone to die and collapse, resulting in severe hip pain and lameness. It is documented across 5 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at 5-12 months. Early signs to watch for include progressive hind leg lameness, pain on hip extension, muscle wasting of affected leg, and reluctance to bear weight. When treatment is required, costs are estimated at £1,500-£3,000 depending on severity, location, and the specific intervention needed. Legg-Calvé-Perthes Disease has a hereditary component, so health-screening certificates from the breeder are strongly recommended for predisposed breeds. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
