How long do you think would be comfortable to leave a five month old puppy in a crate. She stays on our bed at night for about 6 or so hours and in her crate 2 - 3 hours at a time during the day. We would probably be gone for about 6 hours and she would have to be in her crate. We were planning to be away on Sat. and then remembered we can't leave Lucy. Can't wait till she doesn't have to be in a crate and can be left longer. I really appreciate any help!
