In this video from PBSLearningMedia, Brett trains puppies to be seeing-eye dogs. He volunteers as a puppy walker for the Guide Dog Foundation for the Blind. He is working with a puppy named Arty for one year. His job is to socialize Arty and teach him to follow commands. At the end of the year, Brett has to bring Arty back for more training so he will be ready to work with a person who has a visual imparity. Brett knows his work is for a very good cause. When it’s time to give up the puppy, he isn’t too disappointed.
