I have a 7 month old cav puppy. She has started limping on rear paws. She tends to slide on harwood floors and her legs slip and then she will start to limp for 1 or 2 steps. All of the posts on Pattella subluxation are making me very nervous. Breeder has told me that there is no family history at all. Has anyone had slipping and limping issues that were not patella problems?
