My personal belief is that if you don't want your dogs disappearing then keep your yard closed and very private! Out of sight out of mind is the best way. I would guess that the majority of these folks coming up with these huge ass setups are not only ignorant but simply misguided street goons that like to brag and show off there dogs to any other goon who will look and listen. It doesn't make a person or the dog look tough to keep a dog on these types of setups, more so it exposes a lot of ignorance. Just my 2 cents.
