OBJECTIVES: External parasites can be harmful to dogs and transmit pathogens to humans. Dog owners and veterinarians have many antiparasitic treatments to choose from. A discrete choice experiment (DCE) was conducted to inform veterinarians about the characteristics valued by pet owners when selecting parasiticides for their dogs. METHODS: In-depth interviews were conducted with dog owners and veterinarians (N=12) to elicit important characteristics of antiparasitics covering fleas, ticks and/or intestinal worms and lungworm. The DCE was conducted online among UK dog owners. Non-labelled binary choices with opt-out were presented to participants. A pilot study was performed, followed by cognitive debriefing interviews to validate the questionnaire. A D-efficient design was used for the main study. Analysis was performed using a Bayesian multinomial logit model with random effects. RESULTS: Six attributes with two to four levels were selected: spectrum of activity, treatment schedule, veterinarian recommendation, where the product can be obtained, mode of administration and cost per administration. 135 dog owners were included in the main analysis. The most highly valued attributes were spectrum of activity and veterinarian recommendation. Respondents were willing to pay £11.22 (95% CI: £7.88; £15.98) more for protection against fleas, ticks, intestinal worms and lungworm rather than just against fleas and ticks, and £7.23 (£10.48; £4.74) less for a flea treatment only. Respondents were willing to pay £7.21 (£4.45; £10.86) more for a product recommended by their veterinarian. The marginal utility associated with treatment schedule was also statistically significant, whereas those for place of obtention and mode of administration were not. The overall utility of sarolaner+moxidectin+pyrantel was significantly higher than fluralaner. CONCLUSIONS: The most important factors for dog owners when choosing antiparasitics were to have more parasites covered and to be recommended by their veterinarian.
