Okay so about a month ago I got a pekegese puppy from a kennel who is seven months old and been in a crate with his brother since he was a little puppy. He is really laid back, he really shows no intrest what so ever in humans, we have another little dog who he loves to run around the house with a play with, I did not expect them to take so well to eachother so fast but they did. He wants nothing to do with humans unless we have one of his toys. I have tried walking and he refuses he just sits and won't move. I have tried treats and everything else I can think of. He does not like me though, or any other human. I would like him to become more social with humans. He is friendly with the other cats and dogs here but nothing more. Any advice on how to socialize him more with humans?
