How might older people benefit from having a pet?

Well, I believe pets can be particularly beneficial for older people who might feel lonely. The main reason is that caring for an animal gives them a sense of purpose and companionship. For example, my grandmother in Hangzhou adopted a small dog after my grandfather passed away, and it completely changed her daily routine - she started taking walks regularly and even made friends with other dog owners in her neighborhood. Of course, it does require some responsibility, but for many seniors, that structure actually helps them stay active. The emotional bond with a pet can really fill that gap when family members aren't around as much.
