  For it to be happening suddenly, I'd be wanting a vet check. Just in case it's a health related issue. If it's truly a training issue, I would start over again. Act as if you're potty training a puppy to give him a refresher. Lock in kitchen or small area so he doesn't have access to go potty in places he is not supposed to. How long are you expecting him to hold it during the day?  |
