My puppy is not crate trained and I was wondering if it is too late to train her? At night she sleeps in my room with no problem from about 11-845am. Is the crate only used for at night? I was wondering if when I leave my house for a few hours when it's pouring rain outside would it be a good idea to put her in the crate? She is potty trained already. If you could help me out that would be great.
