Sociodemographic correlates of prospective dog owners' intentions to participate in controlled trials of dog ownership and human health.

Female (OR 1.64, 95% CI 1.31-2.04) and older (OR 65+ years 1.49, 95% CI 1.06-2.10) participants were more likely to be interested in taking part in a study investigating the health benefits of dog ownership. Majority reported no incentive was necessary for participation (57%), while others preferred pet food supplies (37%), or vouchers for veterinary care (32%). Over half of participants (53%) were willing postpone adoption for up to 3 months to participate in an investigator-controlled trial. The results of the study, showing majority of participants interested in participating in future studies examining the health benefits of dog ownership and without incentives, provides insight to methodical directions for future studies.
