Limb-sparing surgery offers an alternative to amputation for some dogs with appendicular osteosarcoma, with welfare trade-offs that require careful consideration.
The choice between amputation and limb-sparing surgery for osteosarcoma involves genuine welfare complexity. Amputation eliminates the painful tumor rapidly and allows early return to activity - most dogs adapt quickly and live comfortably on three legs. Limb-sparing surgery preserves the limb but carries high complication rates that may involve repeated surgeries, infections, and prolonged recovery. The welfare-centered decision considers the individual dog's size, conformation, concurrent orthopedic disease, owner capacity for intensive aftercare, and realistic expectations for both approaches. For many dogs, amputation provides better welfare than complex limb-sparing with multiple complications.
