On Monday I bring home the cutest little mutt you ever saw! She’s under a year old, rescued from the home of an animal hoarder. She’s quite timid and submissive, and scared of the outdoors as she was never walked. Obviously no recall or housetraining whatsoever. Any advice on making her transition as smooth as possible, and ensuring peaceful interaction with my ageing whippet (they’re about the same size)? All contributions welcome.
