I listened to this one in the weeks after a friend lost her golden retriever of fourteen years, and I want to be careful about how I frame that, this is not a grief book, and I was not looking for comfort reading. But there is something in Gregory Berns’s central question, “What is my dog thinking?,” that takes on a different weight when you have watched a dog look at a person who loves them and seen what might be recognition, or might be need, or might be something we do not have adequate language for yet. Berns spent years and considerable scientific resources trying to find language for it.
The story is straightforward on its surface: Berns, a neuroscientist at Emory, decided to train his newly adopted terrier mix Callie to remain motionless in an MRI scanner, voluntarily, without sedation, with the goal of being the first researcher to image a fully conscious dog’s brain and observe what it does in response to human cues. His colleagues dismissed the project. The practical obstacles were considerable. The regulatory approval process was novel. What emerged was both a research result and a memoir about what the research process actually looks like when you are doing something no one has done before.
Our Take on How Dogs Love Us
Berns is honest about what the science can and cannot say. The MRI data shows that the caudate nucleus, a brain region associated with anticipation and reward in humans, activates in dogs in response to the smell of familiar humans, not just food. This is meaningful and it is not nothing, but it is not a proof of love in the way the title might imply. The book is admirably careful about this distinction. The title is a question being investigated, not a conclusion being announced, and the nuance with which Berns handles the gap between what the data shows and what he suspects is happening is part of what makes the book scientifically honest rather than merely sentimental.
One reviewer, a dog trainer, offered a pointed critique: why did Berns use luring rather than free-shaping techniques to train Callie for the scanner? It is a legitimate professional question, and it gestures at a gap in the book’s engagement with existing dog behavior science. Berns comes to this project as a neuroscientist, not a trainer, and his methodology reflects that expertise and those blind spots. The critique does not undermine the research results, but it is worth knowing that the book’s approach to training is not universally endorsed within the dog behavior community.
Why the Personal Story Carries the Science
The book works as well as it does because Berns is genuinely writing about two things simultaneously: the scientific project and his relationship with Callie. The training process required an unusual degree of collaboration between owner and dog, and that collaboration is documented in a way that makes the relationship between scientist and subject feel specific rather than generic. Callie is not a dog in this book. She is a particular dog with particular responses to particular cues, and the care with which Berns reports those particularities is both scientifically appropriate and emotionally compelling.
The reviewer who described crying at the book and saying “I know my dogs love me even more now” is responding to something real in the text. Berns is not manufacturing emotion; he is reporting on evidence that supports what dog owners have always believed. The difference between intuition and evidence is the whole point of the project, and the book is effective precisely because it respects that difference.
LJ Ganser narrates with a measured warmth that suits the material. The science sections and the more personal passages have different registers in Ganser’s reading, which helps the listener navigate between them without the shifts feeling abrupt. Seven hours and forty-one minutes goes by faster than expected.
What to Watch For in the MRI Training Chapters
The practical account of training Callie to lie still in a scanner, and then the regulatory and institutional hoops required before actual scanning could begin, is more interesting than it sounds. Berns is good at conveying the specific texture of doing novel science, the skepticism of colleagues, the improvised equipment, the moment when the first scan actually worked. This is what science looks like before it is written up in a paper, and it is not usually available to general audiences in this much detail.
Who Should Listen to How Dogs Love Us
Dog owners will get the most from this, particularly those who have ever sat with a dog and felt certain something was happening cognitively and emotionally that they could not quite articulate. Readers interested in behavioral neuroscience or in the ethics of animal research will find the methodological questions interesting. People who want a straightforward science of dog behavior book should be aware that this is as much memoir as science. Those who have already read Alexandra Horowitz’s Inside of a Dog will find Berns’s approach complementary rather than overlapping, Horowitz focuses on sensory experience, Berns on emotion and attachment.
Frequently Asked Questions
Does the book actually prove that dogs love their owners, as the title suggests?
The book is more careful than the title implies. Berns’s MRI data shows that the reward circuitry in dogs’ brains activates in response to familiar human smells, a meaningful finding. The book frames this as strong evidence rather than proof, and Berns is explicit about the limits of what brain imaging can confirm about subjective experience.
Is the book appropriate for listeners without a science background?
Yes. Berns writes as a scientist explaining his work to a general audience, not for a peer review audience. The neuroscience is accessible and always grounded in observable behavior. Some reviewers with specialist backgrounds in dog training flagged methodological questions, but the general listener will not encounter those as barriers.
How does LJ Ganser handle the shifts between science and personal narrative?
With good calibration. The more personal passages, particularly those involving Callie’s training and Berns’s own relationship with his dogs, are warmer in delivery than the technical sections, without the shift being jarring. It is a thoughtful narration of material that requires two different registers.
Does the book address the ethics of using dogs as research subjects?
Yes, and this is one of the more interesting threads. Berns designed the project specifically around voluntary participation, dogs who indicated distress during training were not pushed, and the regulatory process to get MRI scanning approved for conscious, unrestrained dogs required establishing new ethical frameworks. The ethics of the research are woven into the narrative rather than addressed as a separate chapter.
