Lee Ann Laraway has polio (小儿麻痹症）and is not able to move very much. Most things are out of reach for her. Jeannie, a Labrador retriever, acts as her arms and legs. Jeannie understands 72 or more different commands.
On a shopping trip, she can get cash for Lee Ann at the bank or a candy bar at the store. She can pay the cashier (收银员） and get change back. Jeannie brings things to Lee Ann.
Jeannie was trained at a place called Canine Companions for Independence, located on twelve acres of land in Santa Rosa (California). The land was donated by the late Peanuts cartoonist Charles Shultz. "We train four different types of dogs here, "said Ken Kirsh, a dog trainer there. “Hearing dogs, service dogs, skilled companion dogs, and facility dogs.
Trainers work with Labrador retrievers and golden retrievers for hours a day, but not every dog is good enough to be a working dog.
The work is serious business. Hearing dogs warn their owners of sounds like ringing telephones and doorbells. Other dogs work with disabled patients like eight-year-old Noah Habib who communicates with a special computer. He likes it when people come to ask him about his dog. His father says people are really interested in the dog and will come over and ask to pet her and play with her, and ask about what she does，and these are people that normally might not approach us and want to talk to Noah.
