Meet guide dogs in training, and their owners, including a 16-year-old Paralympic skiing hopeful, and a six-year-old Golden Retriever who's part of Guide Dogs' breeding program.

At puppy school, trainee guide dog Milton tries to nail recall and use a pedestrian crossing. Hester, 16, prepares for the arrival of her new Guide Dog Pickle. Will they be a good fit?

Paralympic skiing hopeful and GCSE student Hester takes potential match Pickle on her first guided walk, and older dog Lando teaches new pup Frankie how to navigate puddles.
