- Dogs that received oxytocin spent longer near their owner compared to dogs that received a control.
- Variation in the golden retrievers oxytocin receptor gene (19131A/G SNP) was found.
- The different genotypes varied in their contact-seeking behaviours. Regardless of oxytocin administration, heterozygotes looked earlier at the experimenter compared to the other genotypes while A homozygotes made physical contact with their owners sooner than other genotypes.
- The different genotypes reacted differently to the administration of oxytocin. Homozygotes, especially A homozygotes, approached the experimenter sooner, while heterozygotes took longer to approach the experimenter after oxytocin administration.
