"Chaser is the most scientifically important dog in over a century. Her fascinating story reveals just how sophisticated a dog's mind can be." -- Brian Hare, author of The Genius of Dogs "After you read Chaser you will realise that you may have underestimated the intelligence of your dog. Marvellous insights into a dog's mind." -- Temple Grandin, author of Animals Make Us Human "This is an extraordinary book full of warmth and wisdom that has the potential to forever change the way we look at dogs." -- Jeffrey Moussaieff Masson, author of Dogs Never Lie about Love "A delightful memoir that offers a challenge to behavioral psychologists and inspiration for pet lovers." Kirkus Reviews "A Border Collie that understands lots of words won't surprise people who work with these inventive dogs, but what makes John Pilley's tale special is his dogged determination, long after his retirement from teaching psychology, to keep his own brain fizzing with all the new words and techniques and ideas he needs to learn to get his results published in a respected science journal." -- Bruce Fogle, author of The Dog's Mind and The Encyclopedia of Dogs "This marvelous blend of good science and heartwarming dog story will inspire all of us to reexamine our canine friends."
