A book I read several weeks ago was called A Small Furry Prayer: Dog Rescue and the Meaning of Life, about a man, Steven Kotler, who falls in love with a woman, and finds himself drawn into the world of dog rescue. A couple of years later he finds himself married to that woman (Joy Nicholson), owner of a small ranch in New Mexico, running a dog rescue.
Kottler is a good writer, and his stories of life with a large pack of small dogs (they rescue mostly, but not only, small dogs, like Chihuahuas and Rat Terriers, etc.) are really interesting. At first he's all "Yay, we're doing a good thing by saving all these dogs, Go Us!" Then when they have a hard time when due to age, illness, and accident, they lose 8 dogs within a few months of each other, it hits him hard. He reports spending many months sitting in a rocking chair on the porch, grieving and thinking about what they are trying to do.
If you have a dog you love, or if you are involved in any way with dog rescue, check out this book. I think you'll like it.
