Yeah, dogs are a scary unknown as many will run right into you trying to bite the noise. As a teenager, my brother and I had trouble with 2 big white Samoyeds that chased us as we tried to exit our neighborhood. The owner was one of our small town's cops and his dogs were always free in his front yard. We complained many times. After a few months of being chased we whopped them with broomsticks when they chased. They stopped chasing us. If you walked by they ignored you but moving fast made you 'prey'.
