Puppy Watches Over Children With Autism

(CNN) -- It was the dog trainer's honesty that won Lisa McMillan over.
When McMillan asked the trainer whether she was able to train a dog to assist with her autistic twin boys, the dog trainer said, "I don't know anything about autism."
The mother did. And Kelli Collins knew how to train dogs. Together, they would train and raise a puppy to be a companion to the then-3-year-olds, Eric and James. Collins would work with the puppy, Caleb, on learning the boys' scent so he could find them when they bolted. He soon would learn to comfort them, almost instinctively, when they needed a friend.
