We adopted a stray that at one point was in a Texas shelter Fast forward a little bit. He's incredible. Outgoing, super intelligent, loyal, goofy, amazing with kids. Does still sometimes bark at strangers if startled, but never bites (even when other dogs have drawn blood).
He's an integral part of the family, and just about the best thing that ever happened to me. Healthy now, and seems to be aware he's got it pretty darn good these days. I can't imagine if it had gone the other way.

Not disputing the tragedy of overpopulation in parts of the world. Not even trying to encourage everyone to go out and adopt a dog. Just wanted to share this experience as a reminder each little guy has their own individual story, and when contemplating large-scale decisions it's important to retain empathy and cognizance of the implications.
