My suggestion is for her to visit some obedience classes and study what breed might work. If her kids are really hellians, perhaps a dog at this point might not be a good idea. I would hate to see a dog picked on by kids...it happens too often and the dog either gets put down because it nips one of the kids in self defense or ends up dumped at a shelter.

I'm sorry, I don't want to be rude, but, the fact that she is not dog saavy AND she has kids that might tease it to death, sends up red flags all over the place.
