I'm hoping someone on here can help me. My puppy Kenobi hates men. When we first brought him home he seemed a little skiddish when my father would come over but he could approach and pet the puppy. Now Kenobi barks at him, runs from him, nips at him, and has even bit him. I thought maybe he just wasn't used to being around guys since there was only females and a young boy in our household now I know it's just something about grown men. We've tried letting my father feed him treats and the puppy will take them and he licks his hands but he won't let my father pet him. Whenever we're around any other guys he acts the same way. I give every guy I know treats to feed him. As the day goes on and my father is around longer he seems to warm up but the next time my dad comes over its like he has to start all over again. Or if my dad makes any sudden movement it scares the puppy. I'm stuck. How can I help my dog get over this fear of men? I don't want him to bite anyone. Please someone help!
