Our Jake--12 yrs-- ruptured a disc (while we were bathing him), resulting in rear leg lameness. He had a laminectomy two wks. ago and the biopsy was negative for tumor, so good news, but not using rear legs yet. Wagging tail, no incontinence, eating, drinking, ready to go. Dr. a bit concerned and suggested we get wheels for him in meantime. Currently have a rear lift harness, but not sure how the wheels would do for him. Anyone have experience with this and recommendations--all welcome.
