Dog to dog aggression while camping

joeshmoe, if your dog runs up to other dogs without an invitation; it is your dog that is not properly socialized. As a former protection dog trainer I can tell you my dogs were extremely well socialized, but if they were on leash and an unleashed dog ran up to them they would warn it off with body language and a low growl. If the loose dog continued it would be seen as a threat to either their handler or themselves and they would take care of that threat. Dogs are a pack animal, they do not like to be run at by others that are not part of their pack. Also anyone who has handled dogs can tell you many times a "friendly" loose dog will attack a leashed dog, it seems to bring out their prey instinct. And it is amazing how many people are clueless about their dog's behavior. I can't count the number of times people have said their dog is friendly and wants to play, when their dog is straining at the leash with every hair standing up and its lip curled into a wrinkle next to its nose.
