I know when we moved into our new house, my baby wouldn't even walk across the room for the first week. We have an open area floor plan with hardwood floors (carpet at the other house). She was curl up in my lap and shiver. It got better with time and now she rules the house
Yours is definitely a different situation, but it may just take some getting used it. Are there other dogs in the neighborhood that could have frightened her? Or is there something in the yard that is out of place and bothering her? Sometimes it's the funniest things. My girl wouldn't go up the stairs all of a sudden and it turns out there was a tiny box half way up- once it was moved, she was fine. The peeing in your lap could be just from stress of the move, but once again, I'm not sure. Just a guess- have you talked to your vet?
