Dogs are special helpers for police officers! They use their sharp noses to find things like lost people or bad guys. When a dog smells something, they can follow the smell to help the officers.
Dogs also help keep everyone safe. They can tell if someone is feeling scared or if they have something bad. When the police need help, the dog is right there to support them.
So, dogs are like super helpers for the police, using their noses and being brave!
