Perceptions of dog owners towards canine gastrointestinal parasitism and associated human health risk in Southeast Queensland

Canine companion animals can carry a number of zoonotic parasites which can adversely impact both human and animal health. Previous studies in Australia indicated that while parasitic infections in dogs are still common and there is variability in the awareness and perception of zoonotic risks among pet owners, the likely contribution of sociodemographic factors to the variation in awareness and perception needs to be further explored. The primary objective of this study is to quantify the relationship between dog owners' knowledge and beliefs about dog parasites and their sociodemographic characteristics. In this study, we surveyed a total of 281 dog owners in SE Queensland between April 2019 to March 2020 and the relationship between dog owners' perception of gastrointestinal parasite infection was assessed using an adaptation of the Health Belief Model, social cognitive framework for health protection. The model looked into the role of dog owners' demography on their perceived severity and susceptibility to zoonotic canine parasites and their likelihood of performing actions associated with worm control of their pets. Our results indicate that owners perceptions about parasitic disease severity in their pets was 26% higher in female dog owners compared to males, in respondents owning dogs over 10 years (27% higher than those owning a dog <3 years) and those owners that regularly deworm their pets and report faeces disposal. Our study indicates that the perceptions of pet owners towards zoonotic canine parasites varies demographically and owner education is important to prevent infection among dogs and control the zoonotic transmission to owners and the community. Finally, there was evidence that increased frequency of visits to veterinary clinics can increase the likelihood of owners performing worm treatment, proper faecal disposal, and cooking meat before feeding it to dogs.

Automated summary

The study revealed that perceptions of pet owners towards zoonotic canine parasites vary demographically, with female dog owners, owners with more than 10 years of experience, and those who regularly deworm and report feces disposal showing a higher awareness of the severity of parasitic diseases in their pets. Increased frequency of veterinary clinic visits was also found to enhance the likelihood of owners performing actions related to worm control, fecal disposal, and safe feeding practices.
