On April 2, 1957, a 5 1/2 month old Border Collie was admitted to Stange Memorial Clinic with a history of a broken leg. The patient was observed to walk normally on the left rear leg but avoided placing weight upon 'the right rear leg. With physical examination and x-ray, the fracture was located at the epiphysis at the distal end of the right femur.
