Glad to hear the dog is enjoying his new home and vice versa. Dogs know a good family when they see one. I agree with Rob, having your wife focus her attention on something new at home is better than a lot of alternatives she could find. She is still getting over the Bozo. Maybe when she recovers she will be happier at home. With her need for money, as you describe it, and two pets, she may not be as quick to try to separate as she has indicated in the past. But you need to get a better deal for you if she stays. She needs to be a lot nicer to you than she has been recently
