I think that he could have moved fast, and startled rocky, just not sure. Rocky is the protective type, especially of me. I am just glad to see preogress! Yesterday for instance, we went out on a walk, and noticed that my Neighbor, and two of his buddies were out side, so we walked over, explained the situation to them, and one at a time, they walked over, Rocky sniffed them, looked back at me, and then went in for pets! He was such a good boy! You could tell he was unsure at first, but after i told him it was okay, he was okay. Once it warms up more, we will begin to go to the local park, so he can interact with more people.
