My dog, Duke will be four years old this August. He is incessantly growing and he now weighs one-hundred pounds. His father was a fullbred German Rotweiler while his mother was an American Pitbull. Duke is a calm relaxing dog inside the house, but once he goes outside he is like a whole different beast. He loves to play fetch as he will do it with tennis balls, frisbees, basketballs, footballs, 4x4's, pretty much anything that he can fit into his jaws and run around with. Here are two pictures of Duke.
