Chuck: Sorry to hear about Pups elbows. My hunting buddy has a gorgeous Lab with same issues. Dog is about 6 now and still hunts well. With all visits to vet you probably have the dog on glucosamine chondroitin and Ascriptin. If not ask Vet. I use for one of my dogs with moderate displaysia on left hip, and x-rays show early signs of early artriits. He is a setter and shows no signs of either, but he is only 4.
