| Guide dogs help lead people who are blind. There are about 14 different guide dog schools in North America. Guide dog puppies are usually born in one of those schools. They train there for about two months. Then they are given to foster parents to train. Foster parents teach them basic obedience such as how to get along with cats and other dogs. Then the dogs learn to sit, stay, come, stop, and leave. They also learn what "forward", "backward", "up", "down", "leave it", and "no", mean. After they learn these, they are ready to be guide dogs. Guide dogs learn to wear harnesses, and to change direction from commands. Guide dogs learn at three different levels. They are quiet, fairly busy, and busy intersections. |
| Hearing-aid dogs help deaf people know when something happens. They tell their owners if a phone rings, a baby is crying, an alarm goes off and much more. |
| Other trained dogs are used by the police to sniff out things, and by farmers to herd cattle. Shelby, an Australian Shepherd, can even sort paper, plastic, and aluminum recyclables. |
