The advantage to Penn Hip is that it can be a reliable indicator of hip laxity on a dog as young as 16 weeks. Sometimes, that information is very useful to have prior to the time the dog is 2 years old. However, the disadvantage in my humble opinion is that the dog must be anesthesized during the procedure and in one of the positions that they put the dog in, the hips are actually displaced. The Penn Hip people say that displacing the hips doesn't actually do any harm to the dog, but I'm not altogether sure I would feel comfortable subjecting my dog to the procedure. Also, in defense of OFA....if the hips are really nicely seated in the socket, it doesn't take a rocket scientist to tell it, and if the dog has severe hip dysplasia, you can certainly tell it on xray without three vets pointing it out to you. It is in the various interpretations of the "fair" that you may run into problems. Myra
