内容简介：
Polo, a six-year-old Golden Retriever, was born in Wayland, Michigan. Leaving his mother, brothers, and sisters, he moved into his foster puppy home. There he learned basic commands and began his socialization training, which lasted one year. He then graduated and went on to receive intense training in Assistance Dog skills for the specific human which was chosen for him. He now lives in Indiana with his human partner. Although Polo is on duty 24 hours a day, he still makes time for fun activities like playing ball, eating homemade dog cookies, and watching television programs about animals.
