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?
It may have something to do with his injury, but a checkup at the vet would be a good idea. If I were you, I would either set the alarm to take him out at 2, and 5, and see if that works. You could also put his bed in an X-pen at night, and put papers down.
