The book should be called "How to Listen to Your Animals" as it is really about that. It does a good job of explaining different domestic animals' face expressions, body language, use of ears and tails and what it all means. By paying attention to the different vocalizations of the animal, valuable feedback into the animal's state of mind can be gained. I found the book interesting and a fun read. However, I did find the chapter on horses to be her weakest one. She had some things right on and some things, not so much. The chapter on birds was interesting as those are the ones I know least about. I laughed a lot in the dog and cat chapters as she was so right about their "language". Yep, that's a cat, alright, I kept saying to myself.
All in all, this is a book worth reading.
