They probably won't be crying to go to the washroom at 8 weeks. You have a tough couple months ahead with house training the dog so start rewarding them early. So make sure you bring the dog outside before you put him/her to bed. I would keep it with you for the first nights. Thats what I did and sometimes my dogs now sleep in there crate or in my room or anywhere in the house. Also I got a puppy 2 months ago and she has been growing insanely and a XL Cage was never a problem. She has never gone to the bathroom inside of it. Hope this helped!
