these laws can even Varry if you pass one state border to another meaning the village you live in is not the world ! if you live near a borderline and have a dog in one state the dog will need a muzzle in the other not if you walk across that border from the state that is free of muzzle to the one that has that obligation you will get punished for the dog not to have had that muzzle, even if you did not realize that you passed the Borderline as there was no sign that you are in another state.
