RE: which breed of dog?
I was in the same situation and decided on the GSP because of the pointing breed as well as the size. I have a young daughter and she is excellent with her. My GSP stays inside as well. They have an excellent disposition but do have alot of energy. They need exercise and entertainment especially for the first three or four years of their life as most dogs do.
A lab was just to big to keep in the house and their tails are always thrashing around and smacking the kids and stuff.
