A Freethinking Dog

I just finished Merle's Door: Lessons from a Freethinking Dog. I love dog stories. This past year I've read The Story of Edgar Sawtelle: A Novel (P.S.) and
The Art of Racing in the Rain: A Novel.
Merle's Door is about a dog and a man who find each other on a camping trip and their life together. Ted Kerasote, the author, portrays Merle as a thinking, feeling creature. When Mr. Kerasote installs a dog door he gives Merle freedom. They live in an area where dogs are not leashed or fenced. Merle makes the rounds of the small town every day and becomes known as the "mayor" who must meet and greet all his constituents. I thoroughly enjoyed Merle's Door and was sad when it ended as our own dog stories do with aging and death.
