I know dogs love to have their belly's rubbed. But is it normal for them to only let their "family" do it? It took Gracie a long time before she would let us rub her belly. I think the first time we were able to was in May, I am not sure about that though. Well Gracie loves every one, my brother, hubby's brothers, mother, and father. She will not let anyone rub her belly. No one except us. Is this normal? Is it because that means she will have to be submissive to them and she isn't cool with that? Or is it because she trusts us enough to let us do that?
