Everything that I have been told about LPs is that the only way to know if it's genetic is if an x-ray has been done and there is scar tissue built up. These dogs can jump off of a couch and injure a knee. This is why many breeders (show breeders included in that statement) are leary to cover LPs in a contract. How can a breeder be guaranteed that an LP was caused by their breeding when a vet hasn't done an x-ray?
