Thanks, that makes sense about the exercise.

I don't want her to always be crated though. Only until I know she will be safe on her own. Then she can have free range of the house. (minus furniture) That's how it's always been with my other dogs.

I'm starting puppy kindergarten soon. I think around 6 months we'll do obedience. I think I heard that's when it's ok to start using training collars and such. (that's what they usually use at obedience classes I've been to.) Though the person I was talking to said I could start her around 8-10 weeks old.
