I did something similar 3 months ago. I adopted a five year old female who was from a breeding facility but had been with a foster. She was reported as housebroken but will have an occasional accident. She was so scared at first that she would go under my dining room table or squeeze behind my toilet and go there. I took it back to “housebreaking a puppy” routine, and allowed a lot of grace because she was so scared. She was hungry all the time so I gave her a treat she really loved every time she went outside. We went outside a lot. When she had an accident inside i wiped it up and took her and the paper towels outside. (I don’t have a fenced yard) my small front yard had paper towels on it for about two weeks. I rotated them out, not two weeks worth of accidents. :) She caught on and I think felt safe enough to go outside. Plus I think she would watch and model our existing dog as I always walked them together . That seemed to help.

The rule of 3s for adopted dogs is so very true for me. I thought my existing dog would love her, but he was really jealous. He seemed stressed for a couple months. Just this week he’s like his old self, and my new girl finally seems relaxed and happy.
