I agree with him. It was his tree, his yard, his dog, his security that was being invaded. What type of doggie to you have? I believe that a dogs bark is a blessing! It lets you know something is lurking. I would have thrown my pet rock at them if they had thrown a rock at my dog..... But like they said. BE CAREFUL! I really hope nothing happens to you or your dog. I've got my fingers crossed for you!
