Roxy, as you all know, lived on a chain for most of her life after we adopted her. On occasion before we moved into our apartment and she had to be taken to my grandfather's house, she did get to sleep inside.

She wasn't inhumanely chained, she had a really long chain, and she received fresh water at least once a day, usually 2-3, especially in hot weather, as well as a healthy diet and human attention EVERY DAY. She also got walked or exercised often, and she was a very happy and healthy girl until we had to have her put to sleep.

Of course, I don't completely support chaining a dog, especially if it's a small chain and they have no food or water access daily, but chaining Roxy kept her safe, and she was happy and well-loved, just as much as any inside dog could be.
