Survey of Spanish pet owners about endoparasite infection risk and deworming frequencies

Abstract

Abstract Background Pets may be carriers of infectious agents including parasites. As part of a larger-scale study covering the whole of Europe, this study examines deworming measures reported by Spanish pet owners and identifies risk factors. Methods An online questionnaire was administered to cat and dog owners in Spain. The replies provided were used to obtain information about the petsʼ living conditions and to accordingly classify each pet into one of the four ESCCAP infection risk categories (A, B, C or D) for which different deworming frequencies are recommended. Questions were also asked about pet care and ownersʼ attitude toward their pets. The Kruskal-Wallis test was used to correlate risk groups with deworming frequencies. Results Completed questionnaires were returned by 500 cat owners and 501 dog owners. According to responses, 96.21% of dogs were assigned to risk category D (maximum risk), and only 1.2%, 2.2% and 0.4% to A, B and C, respectively. Almost all cats were assigned to the minimum risk category A (indoor cats, 62%) or maximum risk category D (outdoor cats, 32.8%); only 3.4% and 1.8% of cats were classified as risk B and C respectively. More dogs were allocated to the higher risk group compared to cats, which were more frequently kept indoors. Cats were reportedly dewormed less frequently than dogs (2.56 and 3.13 times per year respectively), consistent with their different infestation risk. Thus, pets in the lower risk group A were either adequately dewormed or treated more often than necessary. Only a small proportion of cats were not dewormed at all (n = 14). Alarmingly, almost all pets in risk groups B, C or D (representing 95% of dogs and 39% of cats) were dewormed less often than recommended. Conclusions More effective health education is required for the management of zoonotic endoparasite diseases under the umbrella of One Health targeted at owners, veterinarians, general practitioners, and health authorities. To align deworming frequency with infection risk, pet owners should be provided with clear, compelling instructions.
