Depends if you live in the boonies with 40 acres of land and you can let a dog run free without bothering the neighbors and getting into the road.
Chaining up a dog will just make it nuts, if it gets loose there is no telling what it may do. Chain a dog is to prevent them from getting exercise and a feel for their area, poor dogs get hyper protective of their area and this spells trouble.
It upsets me to see dogs placed in kennels, dogs are pack animal and if kept 18 hours a day /7 days away from their humans and any part of their life, they go as strange as a human child would under that circumstance.
Farmers keep dogs in the barn, but these dogs are not chained and have a protective instinct for the cows and sheep and they seldom go 8 hours without a humane to follow or bond with.
Dogs that are let to run free often become what we call Coydogs, dogs that have been abandoned that gather in packs and run down deer or as they have been domesticated have no fear of humans and will attack small children or other small dogs, cats and whatever they can find to eat.
Well, vesta, once again you've taken the topic and run off the end of the earth with it.
I specifically said, "it sounds like the resident asshat needs to put up a fence..." a practice that would have kept the dog that got run over alive. That means, of course, that the resident asshat doesn't have 40 acres and lives out in the boonies.
That makes that point of your post completely irrelevant to the discussion. But relevancy is not one of your strong suits, is it?
This next part is not meant for you, vesta, since you have difficulty staying on point. Read it if you like, but please note I'm not expecting a reply -- though that, of course, is a flaming invitation for you to do so. *sigh*
Anyway....
I live out in the boonies, but I don't have 40 acres. I have a little over three acres. I also live adjacent to a county road with a 55 mph speed limit. More than one animal has been obliterated by the traffic that hurtles along that road.
Ergo, my conclusion is -- if I'm going to get a dog, which is what Mrs E finally bludgeoned me into -- I've got to put up a fence.
About $400 later, a shitload of cattle panels and 6-ft. T-posts and a lot of digging for post holes/gates, I've got a fenced-in area of about 1.5 acres in which both our dogs can run as they please. I should note that while we have a kennel, both our dogs do not live in the kennel 24/7. When we come home from work, they are permitted outdoors to do their business, then they come indoors with us.
They are protected and safe while outdoors, unless some kind of weird shit happens.
That is responsible pet ownership.
