He won't make me care for the dog, but I will end up feeling guilty that I can't help. If I end up doing something for the dog, it will be out of pity for the dog (the dog can't help the owner being irresponsible and putting her into a situation that isn't best for her), but then my body will pay for it.

May not be my mother or my dog, but I do care for him and I know it will throw him off base to have to stay there. He is already struggling. I know it's difficult to understand but we're basically homebodies that get all frazzled when our routines change. It's not about the wifi, or moving stuff, it's that he is already struggling and I cannot advocate for a solution that will have him in more distress.

I need a solution that communicates that we are not a good fit for the dog, and the problem needs to be resolved on her end.
