Though Mr. B is six years old, he still acts like a little puppy. He is really excitable and highly spastic. He'll run around the living room and pushing all of our furniture all over the place. Before we adopted him, he was adopted by this family that had a young child. Apparently Mr. B was returned because he ran full force into the child and stepped on the child. Mr. B has not changed that much since then. He still runs full force around the house and will even try to push us out of the way. He is most excited when either A or I come home and we release him and Ms. M from their teepee and crate. Mr. B will run as fast as he can out his teepee and in the past he would slam Ms. M against her crate. Ms. M has gotten wise and now waits until Mr. B passes by before she steps out. We have thought about changing Mr. B's name to Butkus, Singletary or even Urlacher.
