How many times has a dog owner said “oh he just wants to play” or “he doesn’t bite” just before their wonderful little poochy sinks its teeth into your flesh? Just because the dog hasn’t done it before doesn’t mean that it won’t do it now. Dog owners get very defensive about this. The fact of the matter is that it is the responsibility of the dog owner to control their dog. That means, among other things, keeping it leashed properly. A 30 foot leash doesn’t count in my book.
