Neuroscientist Gregory Berns had spent decades using MRI imaging technology to study how the human brain works, but a different question still nagged at him: What is my dog thinking? You can't ask a dog why he does something. And you certainly can't ask him how he feels. After his family adopted Callie, a shy, skinny terrier mix, Berns realised there was only one way to find out - use an MRI machine to scan the dog's brain. Despite an oppressive maze of bureaucratic hurdles, Berns was determined to proceed with his 'Dog Project', adamant that it would only be conducted under humane conditions, with no restraints - the dogs had to participate of their own free will. Callie followed her nose - and a trail of hotdogs - and led Berns to the discovery of profound and heart-warming new evidence that has unlocked the science behind the canine-human bond. How Dogs Love Us demonstrates why dogs should be treated with love, respect, and appreciation for their social and emotional intelligence.
