I have a 4 year old havanese. He has been crate trained since he was 4 months old. We've had a few accidents overnight over the years that were linked to anxiety as we had a new baby in the house. About 8 weeks ago he was hit by a car and suffered a ruptured bladder and broken femur. He recovered amazingly well from the accident but suddenly over the past 3 weeks he has started pooping in his create in the middle of the night. We stopped feeding him at night about 10 days ago and are religious about taking him out before we go to bed. That seemed to work for a few days but he's stated the behavior again. Does anyone have any recommendations?
