- University of Cambridge researchers analyzed DNA and owner surveys from 1,300 golden retrievers, identifying genes linked to anxiety, aggression, activity level, and trainability.
- Proceedings of the National Academy of Sciences published the genome‑wide association study, the first to demonstrate overlap between canine behavior genes and human emotional traits.
- PTPN1 was associated with aggression toward other dogs in golden retrievers and, in humans, with intelligence and depression.
- ROMO1 correlated with higher trainability in retrievers and, in people, with intelligence and emotional sensitivity.
- A genetic variant tied to fear of other dogs in retrievers also influences rumination on embarrassing experiences and educational achievement in humans.
- Morris Animal Foundation's Golden Retriever Lifetime Study supplied the behavioral data, with owners completing questionnaires on 73 behaviors grouped into 14 categories for the analysis.
Why it matters: Dog owners and veterinarians gain concrete genetic insights into anxiety and aggression, enabling more tailored training and stress‑reduction treatments, while researchers acquire a valuable animal model for human psychiatric traits, potentially accelerating therapeutic discovery and informing personalized interventions for both pets and people.
