I'm really disappointed with this one. I LOVED Berns's first book on animal neuroscience, "How Dogs Love Us," but this one just really missed the mark. While the summary does say that the book discusses a variety of animals, for a book that features dogs in the title, he focuses very little on the dog project itself compared to the previous book. I enjoyed the sections where they explored new avenues for dog brain scanning, but otherwise the sections on other animals were interesting at times but felt very disjointed and without a coherent order to them. The section on the Tasmanian Tiger featured a narrative from the perspective of the last known Tasmanian Tiger and a zookeeper that just felt completely out of place. And the final chapter just completely devolves into a bizarre rant about gene editing and the ethics of future human evolution that just absolutely did not fit in the book. I'm really bummed as I loved the first book and really support the idea of his research, but Berns completely missed the mark with this one.
