response: Yeah, have you ever thought of the various other purposes they provide for people? Dogs can hunt, herd, be a work animal, and even help the handicapped!
original_response: I'm glad to hear it. But of course affection isn't the only role they play. The serve in hunting, herding, pulling loads, protection, assisting police/military, and also helping those who are handicapped or who need therapy!
history: I have three small dogs! They're adorable. Did you know they were the first to be domesticated? They are also been purposely bred over a thousand years for various uses. Wow really? I just bought mine from the breeder and didn't think too much about where they came from. Dogs have adapted to human's actions and can live with a starch diet unlike other canid animals. Yes, mine always seem to know when I am getting sick and they spend time with me.
knowledge: Dogs perform many roles for people, such as hunting, herding, pulling loads, protection, assisting police and military, companionship and, more recently, aiding handicapped individuals and therapeutic roles.
