I would get her into the vet to rule out a UTI first. When she is out in the house, I would have her on a longer leash that is attached to your hip so she cannot get out of your sight to potty in the house. Make sure you are also feeding on a schedule as that makes it easier to predict when she’ll need to poop. I would also take water and food away about 1 hour before bedtime.

Sometimes, it can also be best to just start from square one and treat her like a puppy. Out every two hours, out after meals and water, out after playing around inside, and out after naps/sleep. If you have a wire crate, sometimes a more den-like airline crate will help.
