I found "A Dog's Purpose" by Bruce Cameron on the Barnes and Noble website. I haven't read it yet, but it looks like a keeper.
I can testify to this. There's nothing that makes me feel better than my dog's paw up agains my hand or on my thigh, or his face pressed close to mine. Well, maybe almost nothing. My boyfriend and horse make me feel pretty terrific too.
