"No doubt. We have some in our neighborhood who own mastiffs, rotts, pit bull. A LOT of dog owners let their dogs run around without a leash in residential neighborhoods."
EVery single dog(that isn't a tiny non-lethal dog) that is seen off its leash should be shot on sight. I'm POSITIVE in exurb and suburbs that there are leash laws.
The tiny dogs off leash get one warning to the owner, then they suffer the same fate.
Oh please. Dogs get out of yards and houses. There's a difference between letting your dogs run loose, and escape artists who occasionally get out. If there's a nuisance situation, taking the dog to a vet (or calling the police or animal control) is a much better situation. I've taken in stray dogs and located the owner within a day or two, and have talked to some terribly distraught people. There are cases of dog transporters (working for rescues) accidentally letting the dog get loose, and cases of kids letting out the family dog, etc. Shooting on sight is cruel.
