Thanks, all. Maggie is a full-blooded, albino Great Dane. She is quite a ham. Actually, Danes don't require a whole lot of exercise. We have a fairly small back yard, but she is able to run around it a lot. We also take her out front and play with her. When she's in the house, she doesn't realize just how big she is. She wants badly to be a lap dog, and she is just too big for that. When we tell her to sit down, she backs up to the couch and sits her butt down, with her legs on the floor, sitting like a human, almost. It's funny.
