Police dogs are given special training to help the police with their work. Many different types of dogs can be trained to do this work, but the best known ones are German shepherds and bloodhounds. In Britain, police dogs usually have a 13-week training course and many dogs fail. Not all dogs make good police dogs. They must be completely trustworthy and honest. Most police dogs live with their handlers as part of the family, but they are not pets. They are working dogs and they have a job to do.
Police dogs are trained to chase and hold people who are trying to get away from the police. Police dogs are not vicious animals. They are trained to hold on to people until their handler tells them to let go.
Police dogs often go into dangerous places and they are given special vests to protect them from knife and gun attacks.
Dogs are not only trained to chase and catch criminals. They are also used for following suspects or finding missing people. This is because some dogs, such as bloodhounds, have a very good sense of smell and can be trained to recognize certain types of smells. Some dogs are used to find survivors after earthquakes or explosions and some are specially trained to find dead bodies.
