So our foster pup just got out of the hospital for a respiratory infection and we are trying to really focus on housebreaking. He is about 5 months old, but has been a stray/in shelter/in hospital, so has never worked on housebreaking. We have him in crate when we can't supervise/aren't home. Twice today it was for less then an hour, he had just been outside and gone, and he pees in his crate AND appears to be licking it up. He is soaked in urine. Also, he slept through the night on our bed just fine, without accidents.
The crate is small enough, and we have left him with a stuffed kong (that he has gotten most of the stuffing out of)
