My almost 12 year old girl has torn her ACL. Unfortunately, due to cost and other health issues, surgery is not an option. Has anyone had any luck with a stifle brace? I have 15 years vet tech experience, and know that the success rate of a brace is very low. I don't expect it to fix her, just give her some stability and make her more comfortable. I cannot afford $800 for a brace, but don't expect to get one for super cheap either. Which ones do you recommend?
