I just received a message today from Sonny's sister's owner that his sister has a luxating patella on both of her back legs. I feel so sad for her, she is only 11 months old... I am also concerned about what this means for Sonny.

I knew that cavaliers are prone to luxating patellas, but I didn't realize that they can get them so young. I thought that they usually got them when they are older.
