Its not against protocol to invite her over for help with the dog, as long as you keep it to just that. Thank her if and when she does help and leave it at that. If she brings up anything else, thats fine to talk about. Other than maybe a compliment saying "wow you look really good" when you see her, you got to keep all your feelings and emotions bottled up.
