Oxytocin promotes social bonding in dogs
to test whether oxytocin helps maintain social bonds in domestic dogs
Sociability evolved to :
reduce predation risk
increase ability to find/defend food
plays an important role in several reproductive effects in mammals
helps in regulating various behaviors
competitive success / reproductive performance affected by nature and quality of social bonds
oxytocin and affiliation
Individual's urinary OT values of both experiments were correlated, showing stability over time.
Affiliation with owners
Dogs given OT initiated affiliation to owners more often than when given saline solution
Affiliation with dog partners
Affiliation was affected by type of treatment delivered; after OT treatment dogs affiliated with partners more than after saline treatment
affiliation and endogenous OT
Increases in OT ratio showed no significant association with the time they spent close to owners or dog partners, or interchanging them.
A positive association between change in OT and amount of affiliation reciprocated from partners.
intranasal administration of OT
Significant effect of time, and time by treatment interaction
spray could have caused discomfort in the dogs.
no significant differences in plasma OT levels between saline and OT
