We just bought home a rescue dog yesterday. We know that he is a very submissive and nervous dog. He mostly lays in his bed in the kitchen and won't get up at all, and won't take any treats. Obviously it is all very new to him and the trust for us is not there yet. However we wanted to know if it is better to leave him alone for the time being? Instead of constantly letting him see us and stroking him. Will the lack of interaction make him more wary of us when we do approach him or is it better for him? We are first time dog owners. Any advice would be greatly received
