The purpose of this study was to examine the relationship between pet ownership, different types of pets, and physical and mental health among nurses. The participants were 381 working nursing staff and were distributed online. The results showed that about one-third of the nurses had pets. The overall physical and mental health of pet-owning nurses was better than that of non-pet-owning nurses. Nurses who had pets did not have different physical and mental health status depending on the type of pet they had, and the amount of time they spent interacting with pets did not make a difference in their physical and mental health status. Encouraging nurses to keep pets can improve the overall physical and mental health of nurses. It is hoped that workplaces will implement pet support programs as a humane strategy to improve staff mood and reduce burnout. This will increase the retention rate of nurses and improve the overall quality of work.
