Smokie has a dog house, with a chain. My parents live in a residential area so it's a must. He only goes on the chain though if he has to poop usually. If he has to pee, he takes off so quick and pee's before we can reach for the chain, lol. He deffiently prefers to be inside. In the summers though, he does enjoy being outside, and he has a nice cool shaded area, where he may spend hours out there. He doesn't complain. If he doesn't want to come off his chain yet, he simply won't come in the door. I honestly don't see anything wrong with leaving your dog outside on a chain for certain periods. Now if you have a dog constantly on the chain outside, what kind of life is that? I think that's sad now. .
