Sounds like your singular experience.
Yeah, I live in such a place right now. Dogs can be unleashed on their own property. Leash law applies to public spaces, exempting dog parks. No breed restrictions, which sound silly, anyway.
One time when I was walking my son as a baby in the stroller, had a big growling pitbull wander up to us on the sidewalk ... complete with the archetypical idiot owner calling after it but not actually running and grabbing the damn thing. That wasn't the first time I had that experience with a pitbull, but having it happen with a child was infuriating and scary.
Countless times, you get the random dog running up to you on a trail or at the park, sometimes while you are on a bike, with the, "Oh sorry" owner jogging behind. Just last week, I almost ran over a pit-looking dog absolutely tearing down the trail playing fetch with the owner. I'm always cool about it so long as the dog isn't aggressive (this one wasn't), but I shouldn't have to be.
And are you saying that you don't have to pick up sht from your free-roaming dog? Just wipe it off on the grass?! That doesn't work at all ... unless maybe you have completely flat, smooth soles.
I've had active breeds, two retrievers at one time, and really can't shed any tears for dog owners who find it too difficult to either walk their dog regularly or buy a fence. Don't buy an active breed, then (or probably any dog at all if that's the attitude one brings to it).
prior to leash laws for all, nobody had pit bulls outside bad neighborhoods, because pits etc had to be on a leash and walked many times a day, while non aggressive breeds didn't, so people didn't have pits and aggressive breeds then, or large dogs, and the very few who did, had to have them leashed or fenced just like today.
pit ownership only became a big thing, after leash laws for all, and the huge disadvantage of owning them no longer was present.
the explosion of pit ownership and larger and aggressive breeds, is a direct, if unintended, consequence of leash laws for all, because said laws eliminated the very reason people didn't have them prior..
if your smaller dog doesn't have to be a 2nd job and a pit or large dog does, 99% go with the smaller/medium dog that isn't a 2nd job.
but those wanting a bigger or aggressive breed, were in no different situation than they are now.
they still could have one, but they had to fence or leash them.
