[Shelby&Seymour]

There are many threads on Luxating patellas.You can search the forum and find some good information on it....
Sometimes surgery is required to fix it, depending on how bad it is (there are different "grades" of luxating patella).
Shelby had to have the surgery a few years ago.... it was successful. The surgery was done by an Orthopedic Vet who was very experienced with the surgery..... it was recommended by many here on YT to find a "specialist" to do the surgery, I was glad that I did.
