Book Read: A Small Furry Prayer

I just finished reading "A Small Furry Prayer" by Steven Kotler. This was really interesting - especially because of the struggle this couple had establishing a rescue for Chihuahuas... Some chapters however, were hard to get through when he started writing about philosophers, etc. 
HERE'S A BOOK SUMMARY:  Kotler is a journalist who dove into the world of dog rescue to impress his love interest, now his wife. He did not foresee adopting the least appealing, most troublesome dogs from shelters and living intimately with them until they either were rehabilitated and adopted by others or died in his lap. According to this part memoir and part philosophical study of the dog-human relationship, many of them died on the small farm that he and his wife bought in crime-ridden Chimayo, New Mexico, leaving him very depressed. From the heart-wrenching work, however, he began to find purpose and see how many canine experts have misunderstood dog behavior. Reflecting on the writings of mystics, philosophers, and animal scientists as varied as St. Francis, René Descartes, Claude Levi-Strauss, and Elizabeth Hess, Kotler elevates this tale about saving dogs to a story about human stewardship of life. Rough language and frank descriptions of sexuality may offend more sensitive readers.
