So my pup is about 10 weeks old and when I got him he was really good about whining when he had to go. But now he just poops in his crate with no hint and then whines to get out . This is at night while I'm sleepin FYI. I have a divider so he doesn't have too much room. This is kind of annoying as he will get mess all over him and cleaning at 3am isn't so fun. Any tips on this?
