Okay kiddo, so you know how some people have trouble hearing, seeing, or moving around? Well, service dogs are special dogs that are trained to help those people do things they might have trouble doing on their own.
For example, a service dog might help a person who has trouble seeing by leading them around obstacles and to their destination. Or, a service dog might help a person who has trouble hearing by alerting them when there are important sounds, like a doorbell or phone ringing.
Service dogs are really, really smart because they go through a lot of training to learn all of the things they need to do to help their person. They also wear special outfits, like a vest, so that people know they are working and should not distract or play with them.
It's important to remember that service dogs are not pets, they are working animals, and should be treated with respect and kindness. So, if you see a service dog, you should not distract or pet them, but let them do their important job!
