What did the University of Cambridge study find about dog genes?

The study found that genes linked to human emotions like anxiety and depression also influence dog behavior and personality traits.

Which specific genes connect dog and human emotions?

Genes like HUNK, linked to nervousness in golden retrievers and worry in humans, and ASCC3, associated with noise phobias in dogs and mood swings in people, show a connection.

How can understanding dog genes help pet owners?

Knowing that genetic factors can predispose dogs to sensitivity and anxiety can foster greater empathy and understanding of their behavior.

Shared Genes: Humans and Dogs Feel Alike

New research indicates a striking genetic connection between human emotions and canine behavior. A study analyzing 1,300 golden retrievers found that genes influencing human anxiety and depression also shape their personalities. For example, the HUNK gene is linked to nervousness in golden retrievers and worry in humans.

Further analysis revealed that genes associated with fear of loud noises in dogs, like ASCC3, are also connected to human mood swings and irritability. Even genes related to intelligence, such as ROMO1, show similar patterns in dogs' learning abilities. Twelve genes identified in golden retrievers were found to also underlie human behavioral traits and emotions.

These findings, published in PNAS, suggest that genetic predispositions can make some dogs more susceptible to stress. Understanding these links can help owners develop empathy, recognizing that certain behaviors might stem from distress rather than willful disobedience. This research highlights a shared evolutionary heritage influencing emotional states in both species.
