There are four parts to Mr. Campbell's book. In part one ("Domestic Companions"), there are stories about Lulu the pot-bellied pig, Dory the rabbit, Inky the cat, Stormy the quarter horse, and a number of dogs including Frisky, Honey, and Toby. Part two ("Trained to Serve, Inspired to Heal") contains tales about Fonzie the dolphin, Molly the pony, and dogs including Endal, Trakr, and Cheyenne. In part three ("Wild Saviors") we read about Jambo the gorilla, Lulu the kangaroo, Ningnong the elephant, and Mila the beluga whale. Lastly, in part four ("Legends and Folktales") there are stories about Mediterranean dolphins, wolves in India, and a variety of dogs. These animals, and others, do all sorts of things ranging from scenting diabetes, saving a woman having a heart attack, finding an abandoned baby, and saving a woman from drowning. They clearly show how widespread compassion and empathy is among diverse animals, and how it readily crosses species lines.
Mr. Campbell's introduction is a wonderful read about how he carefully analyzed each of the stories for its credibility, and he provides a valuable introduction to the sorts of analyses that are needed to fully understand what a particular animal did and why. And, by sticking to the science, one can feel confident that the stories are told in a most reliable manner. Mr. Campbell also writes about controversial issues in the study of animal behavior and animal minds, and fully recognizes that it is often hard to "prove' what an animal knows and feels and why she or he did something. However, this lack of certainty, in and of itself, can open the door for much needed further study.
