I will admit that when I was a kid our dog was chained outside. But honestly, he didn't like it in the house, LOL. If he was brought in, he'd sit by the door trying to get back out. We couldn't have fences where we lived, so he had to be chained out. He could crawl under our porch for shelter and never would use the dog houses we got for him.
So.. while I HATE to see dogs chained out, I do always try to reserve judgment as long as there is shelter because I remember ol' Pokey very well. He HATED being indoors, even if it was stormy out, he preferred it outside.
Believe me, my sisters and I tried and tried to get him to be our house-dog, LOL.
