For millennia, we've wondered what dogs think; neuroscientist Gregory Berns and his team hoped to figure out at least how dogs think, and so trained them to go into an MRI scanner. Berns writes with insight, empathy, and humor as he reveals the results, while also taking us into the minds of wild animals: sea lions who can learn to dance, dolphins who can see with sound, and even the now extinct Tasmanian tiger. As pet owners might expect, Berns's findings prove conclusively that animals have feelings very much like we do—a revelation that forces us to reconsider how we treat and consider animals.
