comes up to you and the hair on his back is raised. Last summer my grandson and I were walking our two dogs. One was a large breed and the other a small breed who was a puppy at the time. This dog came out of nowhere (looked like a german shepherd) and came running and barking at us w/the hair on his back raised. Then the hair on the back of my large dog was raised as well. Luckily we weren't far from the house and I called to my son who came running out. At first, my grandson tried to run to the house to get his dad, but the dog looked like he was going to follow him so I told him just to stay put (by me) and don't move quickly. However, my two dogs were barking as well and trying to get to the dog. It was scary for a couple of minutes until my son got the dog to leave. What do I do if this happens in the future? Which leads me to the next question... what to do if a dog attacks your dog or another person???
