I think most vets can tell if the patella is o.k. by feeling for looseness but I really don't know if many breeders actually get x-rays. The patella's can get injured very easily by excessive jumping. If you see your Yorkie skipping with their hind leg then that is usually sign of a luxating patella and it should get checked right away, otherwise you might just want to wait until they are about a year old. |
