Chaser has a way with words. She knows over a thousand of themâmore than any other animal of any species except humans. In addition to common nouns like house, ball, and tree, she has memorized the names of more than one thousand toys and can retrieve any of them on command. Based on that learning, she and her owner and trainer, retired psychologist John Pilley, have moved on to further impressive feats, demonstrating her ability to understand sentences with multiple elements of grammar and to learn new behaviors by imitation.
Johnâs ingenuity and tenacity as a researcher are as impressive as Chaserâs accomplishments. His groundbreaking approach has opened the door to a new understanding of animal intelligence, one that requires us to reconsider what actually goes on in a dogâs mind. Chaserâs achievements reveal her use of deductive reasoning and complex problem-solving skills to address novel challenges.
Yet astonishingly, Chaser isnât unique. Johnâs training methods can be adopted by any dog lover. Through the poignant story of how he trained Chaser, raised her as a member of the Pilley family, and proved her abilities to the scientific community, he reveals the positive impact of incorporating learning into play and more effectively channeling a dogâs natural drives.
Johnâs work with Chaser offers a fresh perspective on whatâs possible in the relationship between a dog and a human. His story points us toward a new way of relating to our canine companions that takes into account our evolving understanding of the way animals and humans learn.
