I have new rescue. He has no accidents during the day. I let him out several times. However, night time is a different story. I let him out as late as 11:30 p.m. and I'm up around 6:30 a.m. and I will still find an accident (poop only). I have been crating him at night. Last night he managed to find a way to poop just outside and through the door of the crate!! His last meal is around 4:00 p.m. in the day. I need suggestions what else I can try to correct the problem.
