She is absolutely NOT mad at you for the change. Dogs simply do not work like that. They are not little furry humans and you can't apply human psychology to the dog. Dogs live in the moment and adjust to change WAAAAYYYY faster than humans can. Living with a dog is like living with a little Buddhist monk in that respect!
Here's my ideas:
1) Because you moved I'm going to venture the following, which I see as the most likely hypothesis:
In your old house the dog knew the boundaries of it's "den", namely, the entire inside of the house and in particular close to where she slept.
In the new house she still needs to get her bearings. She doesn't know where the "den" starts and stops. The reason she knew that in the old house is because you taught her (you house-trained her). Now you're expecting her to work it out for herself and she's having some accidents, which means she could use a little guidance.
My advice, therefore, would be to repeat the process of house-training her pretty much as if she were a puppy. It will go quickly because she's been through it before. The problems should clear up in a short time. If you don't remember the steps in house training a puppy then Google is a goldmine.
2) YOU are also very distracted (I would assume) because of the move. Your dog MAY be giving you the signs that she wants to go outside but you may not be picking up on it. Pay close attention to her.
3) Your dog may not want to go outside (yet) because the neighbourhood is new/foreign and scary to her. Take her on LONG walks (2 hours) through the neighbourhood at least 3 times a week for a week or two so she can get grounded, as it were. If she's feeling anxious about what is beyond the front door than this will fix it.
You mentioned that you suspect a medical cause (UIT infection). If that's the case then a quick trip to the vet might be a good idea. This will also give you a chance to introduce yourself and your dog to the new vet. On the surface of it this is not what I would expect but I have no medical knowledge and I think a trip to the vet when you don't know what's going on is always a good idea.
Good luck. Keep us up to date. It's really nice to hear back if things you suggest work or not.
