Objective: This study aimed to compare pet owners’ knowledge of antibiotic use, understanding of antimicrobial resistance (AMR) and antibiotic practices for themselves and their pets to guide behavioral interventions to reduce AMR. Methods: A cross-sectional study conducted between March 2023 and December 2023 involved 1080 pet owners recruited from 16 veterinary clinics in Singapore. An anonymous self-administered survey assessed the participants’ knowledge of antibiotic use and AMR as well as their adherence to recommended antibiotic practices for themselves and their pets. McNemar’s Chi-square test was used to identify significant differences in the outcome variables between self and pets. The differences between the type of pet owned (dog owner/non-dog owner) were assessed using Pearson’s Chi-square test. Results: Among the 1080 pet owners surveyed, poorer knowledge of antibiotic use (46.3% vs. 33.2%; p < 0.001) and inappropriate antibiotic use (33.9% vs. 23.5%; p < 0.001) was more common for participants’ pets than for themselves. Compared to dog owners, non-dog owners had poorer knowledge of antibiotic use for their pets (poor knowledge, 55.2%; 42.4%; p < 0.001), but the knowledge of AMR occurrence and antibiotic practices did not differ between the dog owners and the non-dog owners. Conclusions: Pet owners have significantly poorer antibiotic use knowledge and antibiotic practices for their pets than for themselves. Compared to dog owners, non-dog owners have poorer knowledge of antibiotic use. Educational initiatives addressing pet owners’ knowledge deficits may improve their antibiotic practices for their pets and themselves, emphasizing the importance of cross-sectoral One Health planning.

Background: Shared decision-making (SDM) can improve appropriate antibiotic prescribing in human primary care clinics, but little is known about it in the veterinary setting. This study examines the association between SDM and antibiotic prescribing for cats and dogs in veterinary clinics, then determines the key factors influencing SDM through a value-driven approach. Methods: This cross-sectional study surveyed 41 veterinarians practicing in Singapore veterinary clinics. Appropriate antibiotic prescribing was defined as concordance with local antibiotic guidelines for companion animals, while an adapted SDM-Q-9-Doc scale measured SDM on antibiotic prescribing with pet owners. Questions were developed to measure constructs of the VALUE model and factor analysis was conducted to identify latent factors. Multivariable logistic and linear regressions were performed to assess the association between SDM and antibiotic prescribing, and determinants of SDM, respectively. Results: Antibiotics were most inappropriately prescribed for cats/dogs with ear infections (cocci observed) (63%), and periodontal disease (59%). Engaging owners in SDM (AOR 1.31; 95% CI 1.05, 1.62; p = 0.014) was positively associated with appropriate antibiotic prescribing for cats/dogs with periodontal disease. After adjusting for age, gender, clinic role and practice type, veterinarians with a higher overall VALUE score (β = 0.14; 95% CI 0.02, 0.26; p = 0.021) were more likely to engage in SDM with owners on antibiotic prescribing. Conclusions: SDM with pet owners improves appropriate antibiotic prescribing for cats and dogs, though effects vary by clinical scenario. Aligning AMR-related values between veterinary clinics and veterinarians to enable effective communication with pet owners can promote SDM and subsequently drive appropriate antibiotic prescribing for pet cats and dogs.
