I guess it'll be ok if this young pup stays. He's pretty respectful, so far...but he keeps getting bigger. First he was the same size as the little dogs. Now he's halfway up to me. I don't think he likes to run fast just for fun. He seems to mostly like to fall down on a little dog for fun. Never saw a game like that before. I think he's getting bigger because he stretches so much while he's sleeping. Its ok he likes to sleep in front of the fan, but he always lays down on and plugs the cold air vents. and then it stays hot. that's no good.
