Our pup was doing really well, ringing the bell hung at the back door when she wanted out. She was doing this at 4 1/2 to 6 months old but just within the last week or two she’s been peeing or pooping in the house. She has not even bothered to ring the bell. Is there a time they go through when they back slide? I know they are a stubborn lot. Thanks in advance for any feedback.
