If you love dogs, you have to read this book. It is fun but also really pulls on your heartstrings. 

My favorite part:
"And it is exceedingly short, his galloping life. Dogs die so soon. I have my stories on that grief, no doubt many of you do also. It is almost a failure of will, a failure of love, to let them grow old - or so it feels. We would do anything to keep them with us, and to keep them young. The one gift we cannot give."
