Hello, we just got a 8wk old yellow lab puppy a week ago,he does really well during the day in his crate and no accidents at all, in fact when I let him out of it he runs to the door and waits if he has to go. The problem is that even after meals he doesn't poop, it takes him around 3 hours to go potty after a meal ( which doesn't seem normal to me) and also it is at night between 12-3am that he poops in his crate nonstop, like 4 times. During the day and first times he poops at night it is a normal consistency, but after his second stool movement around 1am it looks like diarrhea... Help please!
