The argument about the dog in its own yard is ludicrous. It doesn't matter, most laws state dog must be under control within city limits. If there is a leash law where they live the dog has to either be on a leash, tethered or contained within a fence. I consider myself a very responsible dog owner and one of my dogs has very good voice control. I still don't let her wander out in the front yard unattained or unattained too. It is my responsibility as a pet owner to control my animals in order to keep the common public safe.
