"This is my dog. His name is Bud and he is a 7 year old Golden Retriever and Tibetan Mastiff mix. I call him a "Golden Mastiff." He is just over 28" at his shoulders and weighs 112 pounds. He has the guardian personality of a Tibetan Mastiff: he is reserved with strangers and doesn't like other dogs. He is very loyal to those he knows well, and very protective of his "sister," an American Pit Bull Terrier. Bud loves to swim and play ball, like a Golden Retriever."
