A few days ago, Reggie yelped while he was playing and went running off holding his right leg up in the air, then it was back to all fours and he seemed fine. A little while later, he was standing up on his hind legs when he kind of collapsed to the ground (he didn't cry or yelp) and when he stood up, he was holding his left leg in the air. After a short time, he was walking on all 4 legs like nothing happened. I made an appointment with the vet and my husband took him. The vet confirmed Reggie has luxating patella and will probably need surgery.
The vet didn't give it a rating (I know from reading posts here that the rating indicates the severity). The vet did suggest surgery at a cost of about $500 per knee. Luckily I have pet insurance so it won't cost me quite that much. I plan to get a second opinion.
Is there anything I can feed him or any exercises or other things to try and strengthen the muscles in his legs to help support his knees? I'd appreciate any advice or suggestions.
Thank you
