I agree with you. A dog can easily run the distance of two houses in a couple of seconds. You don’t have the time to decide if he’s a nice pitbull or not a nice pitbull.
I don’t have a problem in this situation. If the dog was in the backyard and tied up or if the dog was of a breed that isn’t known for attacking and biting people, then I would have a problem.
Only a douche bag or a dog fighter would tie up a dog confined in their own yard.
