Oban has people he seems to like much more than others. My sister, the lady across the street, a friend of the OH. I'm sure he would happily live with my sister. Her dog doesn't seem to miss her when she's been here for a couple of week long visits. Every dog I've ever found seemed content with me but happy to get back with it's owner when I found the person. I think most dogs adapt to a new home very easily. My dog only once went home with someone else on a walk, mind you he tried to more than once. Mostly he chooses me. I bet your dog is the same.
