Shared Genes: Humans and Dogs Feel Alike
25 Nov
Summary
- Genes influencing human anxiety and depression also shape dog personalities.
- Specific genes like HUNK link golden retriever nervousness to human worry.
- Understanding genetic links can foster empathy for distressed pets.

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.
