We've only had our rescue greyhound for four weeks and he's a dream, lovely on the lead and relaxed and affectionate in the house. Although apparently not so much when I'm not there. When I go out and leave him alone with DH he chews, runs around the house knocking things over and won't settle at all. If neither of us are home, whilst I obviously don't know what he does, we come home to a relaxed dog, lying on his bed with nothing chewed, knocked over etc. So this behaviour does seem to be specific to DH. When we first got him I had to go away for a couple of days so if anything I thought he'd have bonded more with DH. Any ideas how to balance the relationships?
