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 even leave all their money to their pets when they die!

Animals can help people, too. Dogs can be taught to become the “eyes” for a blind person or “ears” for a deaf people. Scientists have found that pets help people live longer! They make people happier, too. Because of that, animals are brought into hospitals for “visit”.

Americans hold “Be---Kind-to-Animals Week” in the first week of May.

Pets shows are held during the week. Even if you don’t live in America, you, too, can do this. How? First, think about how animals make your life richer. If you have a pet, take more time this week to play with it. Remember to give it delicious food. Also, be sure to keep your pet from those unwanted babies.

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.
