Antimicrobial resistance in companion animals: trends, threats and takeaways

Summary

Antimicrobial resistance (AMR) in companion animals is increasingly recognised as a threat to both animal and public health within the One Health framework. Although extensive research and surveillance initiatives have focused on AMR in humans and food-producing animals, comparatively limited attention has been given to companion animals, despite their close contact with people and potential role in transmission of antimicrobial-resistant organisms. This article synthesises current knowledge on AMR in dogs, cats and other companion species, highlighting patterns of resistance, surveillance initiatives across different regions and temporal trends in prevalence. The article further examines clinical implications of AMR for companion animal medicine based on available data, as well as the potential for interspecies transmission, and discusses important risk factors.
