New to site. Our 3 year old beagle/boxer mix, Chevy (pronounced like Chevy Chase), lost his left front leg as a puppy prior to our adopting him from a rescue organization. After becoming lame in his rt back leg recently, he was diagnosed with bilateral luxating patellas (grade 3/4). From everything we have researched, it looks like surgery will be necessary, 1st in the rt and then in the left leg. He is extremely active, and loves to play with our other dog. We are very concerned about his post op recovery and risk of recurrence. Have been told it is 3 months with constant kenneling, leash walking only, and no play. Plan is to do the surgeries a month apart. Any thoughts to make his situation better?. We were going to purchase a special sling. Is there any special rehab that might push things along faster and decrease risk for complications? How do tripawds usually do in these situations? Are we making the right decision with doing surgery?
