Series 1

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.

Guide Dogs' assessors arrive to consider whether Hester is ready to be paired with Pickle on a permanent basis. Plus: will Kinky's tail allow him to continue his guide dog journey?
