Why do dogs speak so profoundly to our inner lives?

When Mark Doty decides to adopt a dog as a companion for his dying partner, he finds himself bringing home Beau, a large golden retriever, malnourished and in need of loving care, to join Arden, the black retriever. As Beau bounds back to life, the two dogs become Mark Doty’s companions, his solace, and eventually the very life force that keeps him from abandoning all hope during the darkest days - their tenacity, loyalty and love inspiring him when all else fails.
