Griz is just like that around one of my dad's friends. Whenever he comes over, Griz runs into the other room. I know that Griz wants to go over to him, because he inches over very closely. But whenever my dad's friends inches his arm out, Griz runs away to the other room again. In the backyard it's the same way. He'll play with Kody, but when he sees my dad's friend, he freezes and backs off. Griz was abused as a pup, but he wasn't there for long, and my dad's friend doesn't resemble the abuser at all.
