I just picked up a Silver Lab for a bunch of dollars, that I was told was in good condition and is a pure bread with Akc papers. I took Grace to my vet and was told: Right Rear hock/paw - Dog stands at rest with tarsus and toes hyperextended. no swelling or pain detected. Suspect conformational abnormality. Recommend radiographs if lameness develops or problem persists. I'm in love wit he dog but really wanted a hunter. What should I Do.
