The human volunteers main job is to make sure the dogs dont get burned out, which means taking a break to play ball or nap after about two hours of work. Although some handlers have a background in counseling or pastoral care, the biggest part of their training is just learning to be quiet, Hetzner said.

　　I think thats a common mistake people make in crisis situationsfeeling obligated to give some sort of answer or advice, when really, those who are hurting just need to express themselves.

　　The Human-Canine Bond

　　Why does petting a dog make us feel better? Its not just because theyre cute, says Brian Hare, director of Duke Universitys Canine Cognition Center.

　　The human-canine bond goes back thousands of years. Dogs descend from wolves and have been attracted to humans ever since we began living in settlementsa source of tasty garbage. That created an advantage for wolves to live near humans, and since it tended to be the less aggressive wolves that could do this more effectively, they essentially self-domesticated over time, according to Hare.

　　Part of what makes dogs special is that they are one of the only species that does not generally exhibit xenophobia, meaning fear of strangers, says Hare.

　　Weve done research on this, and what weve found is that not only are most dogs totally not xenophobic, theyre actually xenophilicthey love strangers! Hare said. Thats one way in which you could say dogs are better than people. Were not always that welcoming.
