Antimicrobial resistance is one of the major challenges in public health, and the spread of resistance has garnered widespread global attention. Antibiotic resistance genes (ARGs) are the root cause of bacterial resistance. ARGs proliferate and transfer through various pathways, migrating and spreading among the environment, animals, and humans, posing a threat to public health. Therefore, it is particularly important to maintain and strengthen surveillance efforts in key areas where ARGs are highly likely to evolve and transfer between organisms. Companion animals share close relationships with humans, which may increase the risk of ARG transmission, yet related reports remain limited. This article primarily reviews the detection methods, results, and transmission status of ARGs in companion animals, aiming to enhance understanding of the prevalence of ARGs originating from companion animals and elucidate the sharing and transmission of ARGs between companion animals and their owners. It provides technical support for research and control of antimicrobial resistance transmission between animals and humans.
