I bought in a puppy, and a mad one at that, as company for my old boy who was 12 at the time as we had lost his companion. He had numerous ailments, but have to say that she gave him a new lease of life, and he was with us for another 2.5 years. It was hard work at first, as the puppy had to learn to leave him alone when he wanted to sleep, she soon got the message though. He used to look out for her and sleep beside her and at times I dont think he would have been bothered to go outside at times had she not been out there.
