Groundbreaking study reveals genetic overlaps in anxiety, intelligence and emotional regulation between humans and their golden retrievers
New York, N.Y. – A new study published in the Proceedings of the National Academy of Sciences has uncovered remarkable genetic parallels between golden retrievers and the humans who love them, suggesting that the bond between the breed and its owners may run deeper than affection—it may be written in DNA.
Researchers at the University of Cambridge and the Morris Animal Foundation compared genomes from more than 1,300 golden retrievers enrolled in the ongoing Golden Retriever Lifetime Study with large human genetic databases.
The results, released November 18, 2025, show that certain behavioral traits in the popular breed map directly onto the same genetic pathways that influence human personality, intelligence, and mental health.

A Breed Chosen for the Experiment—and Perhaps for a Reason
Golden retrievers were not selected at random. The Golden Retriever Lifetime Study, launched in 2012, is one of the largest longitudinal canine health projects ever undertaken, tracking thousands of dogs from puppyhood through old age. Because all participants are purebred golden retrievers, genetic noise is reduced, making it easier to spot meaningful signals.
Owners of the 1,300 dogs aged three to seven years completed exhaustive behavioral questionnaires—over 70 specific items—that were grouped into 14 broad traits, ranging from trainability and energy level to fearfulness and aggression toward strangers.
Dr. Eleanor Raffan, a veterinarian and geneticist at the University of Cambridge who led the analysis, called the convergence “really striking.” In an interview, she explained: “The findings provide strong evidence that humans and golden retrievers have shared genetic roots for their behavior. We’re seeing the same genes influencing how anxious a dog gets and how prone a person is to worry.”
Specific Genes, Shared Stories
Among the standout discoveries:
- The gene PTPN1, previously linked to human intelligence and cognitive processing speed, also affects aggression levels in golden retrievers.
- Variants in ROMO1 correlate with trainability in dogs and emotional sensitivity in people.
- HUNK and ASCC3 regions, associated in humans with neuroticism and mood disorders, influence nervousness and fear responses in the breed.
Perhaps most intriguing is the overlap in rumination—the tendency to dwell on negative experiences. Dogs that scored high on “owner-directed attention-seeking after correction” carried variants also tied to prolonged negative thinking in humans.
“We all joke that golden retrievers look guilty for hours after stealing a sandwich,” Raffan said. “It turns out that lingering guilt may share a biological basis with the human habit of replaying embarrassing moments at 3 a.m.”
Implications for Training and Veterinary Care
Dog behaviorists say the findings could reshape how trainers and owners approach common challenges.
“Knowing there’s a genetic component to excitability or stranger-directed fear doesn’t mean we throw out training,” said Dr. Brian Hare, director of the Duke Canine Cognition Center (not involved in the study). “But it does mean we can set realistic expectations and use methods that work with biology rather than against it.”

Veterinarians see potential clinical applications as well. Medications developed for human anxiety disorders target many of the same pathways now implicated in canine fearfulness.
The overlap could accelerate the repurposing of existing drugs for dogs—or even inform breeding practices aimed at reducing extreme anxiety in the breed.
Why Golden Retrievers?
The Co-Evolution Hypothesis
Scientists have long noted that golden retrievers consistently rank among the most “human-attuned” breeds.
The new genetic evidence lends weight to the idea that centuries of selective breeding for companionship—rather than just herding, hunting, or guarding—may have inadvertently mirrored human emotional and cognitive profiles.
“Golden retrievers were bred to work closely with people, to read human cues, and to remain calm under pressure,” Raffan noted. “It appears that, over generations, the genes that made them good partners also made them genetically more similar to us in temperament.”
A Mirror in Fur

For the millions of Americans who share their homes with golden retrievers—approximately 2.3 million households, according to the American Kennel Club—the study feels less like science and more like confirmation of a long-held suspicion.
“They really are little blond versions of ourselves,” one study participant wrote in the questionnaire margin, a sentiment echoed in countless social-media posts showing goldens displaying uncanny empathy, comedic timing, or dramatic flair.
The research also raises a lighter, almost philosophical question: when a golden retriever stares soulfully after being scolded, is the dog reflecting its own genetic tendency toward rumination—or mirroring the owner who can’t let go of the moment either?
As Raffan put it: “Maybe the reason we love golden retrievers so much is that, on some level, we recognize ourselves in them.”
Summary
In a landmark study, scientists have found that golden retrievers and their owners share genetic pathways influencing anxiety, intelligence, emotional regulation, and even the tendency to dwell on mistakes—suggesting the beloved breed’s personality may literally mirror our own.
