These tests are not inexpensive to do and the symptoms may not be noticable for years. These results are also reported to AKC with the owner of the dog and breeders name. A reputable breeder would want to do everything they could to ensure the soundness of their dogs, but some might not be so honest. These could be some of the reasons there is not more testing done in Yorkies. My girl still does not show symptoms and this is not unusual in small dogs as long as they do not get over weight. There is another new test, Penn Hip, that is suppose to be even more accurate than the OFA test. |
