Not long after the arrival of our puppy Lila, I lay in bed one night listening to a podcast about Puppies Behind Bars, a nonprofit group that teams up puppies with prison inmates, who then live with and train the puppies to work as bomb-sniffing dogs, or service dogs for wounded soldiers.

I found this podcast pretty compelling…especially the description of the powerful and healing relationship that develops between dogs and prisoners — and I highly recommend listening to it yourself on the National Public Radio website — but what had immediate personal relevance and caused my eyes to snap open was learning how the dogs were matched with a career based on personality type.
