I am so sorry to hear about your puppy. I lost my puppy last August just a wek after his first birthday. He started having problems with his back legs and then came down a high fever that he was put on steroids for the fever and his lymph glands were all swollen, turns out he had an auto immune disease and there was nothing we or the vet could do. I know losing a furbaby is so hard because there are part of you family, but we buried him in the backyard and I planted Tulips on his grave and put a white picket fence around it.
