Pippa is almost three, and I'm a little worried about her. For the past week or so, she has been sleeping more than usual, doesn't seem interested in doing much and distances herself. She's up and ready for a walk, though, at a moment's notice and gets excited when someone comes to the house. We thought it might be that she was staying inside more because she was hot and it is warming up outside. Getting her clipped hasn't seemed to make much of a difference. I would guess that if there was something really wrong, it wouldn't matter what was going on around her. Thoughts?
