Pet Sitter - Now Hiring

Dog gets very suspicious of anyone if me (the owner is not around) Id like to go on a couple walks with you before you start doing it on your own because he does not trust other people at all. Extremely gentle and loving dog, he was a rescue from an owner that abused him so he just needs a little extra reassurance during some walks. Ive never seen one sign of aggression from him towards other dogs or people the worst is just him being scared when people enter my house without me.
