I have a lurcher who is two called Perry, I was out walking with him yesterday with two pure breed whippets, and we noticed that his back right leg kicks out when he is running at speed. His gate was certainly not normal... I'm really worried about him, he is roughly 2 years old, I rescued him from a shelter, and the vet checked him over, gave him his jabs etc, but this leg thing is something I've just noticed... Any advice is very welcome before I take him to the vets...
