They look a lot better than a lot of the hips posted here. The heads are in the socket. I am surprised you are seeing symptoms from this, and depending on the age of the dog, I would be wondering if we have some pano going on that is causing the dog to be ouchy.
I agree send them in to the OFA. If the breeder won't accept the OFA's determination, then that is telling. But not all vets are created equal when it comes to reading x-rays, or taking x-rays for that matter. And trainers, well, HD can only be diagnosed by x-ray. There are a host of reasons dogs will limp, from back problems to pano to muscle sprains and strains and foreign objects stuck in the foot, even too long or infected toenails.
The hips look pretty good.
