Based on the real-life memoir by best-selling author Jon Katz, A Dog Year tells the story of a 50-something writer in mid- existential crisis, who impulsively agrees to adopt a high-strung border collie named Devon. At first, the dog wreaks chaos on the household Jon shares with two older, mellower Labs. But as Jon learns to let go of the hostility in his own personality, he finds his ability to train and communicate with Devon much easier. Ultimately, the experience transforms both man and dog in meaningful, unexpected ways.
