In America, when people say "man's best friend", they don't mean another person. Instead, they are talking about a lovely animal: a dog! These words show the friendship between people and animals. Dogs and other pets can give happiness to people's lives. Some people think of their pets as their children. A few people even leave all their money to their pets when they die!
If you don't have a pet, be kind to animals around you. For example, if you see a street dog, don't kick it or throw things at it. Instead, just leave it alone, or better yet, make friends with it. If others around you do bad things to an animal, try to stop them. As people, we must protect animals who can't speak for themselves.
