Meet Patriot, Potomac, Primrose, Poppet, and Phil - five determined puppies who, from the moment they're born, begin an incredible journey to become guide dogs for the blind. It's a rigorous two-year process that will take them from the care of selfless foster volunteers to specialised trainers to, if they make the cut, a lifelong human companion. At every step of the way, the puppies will be tested, challenged, and evaluated. But not just any dog makes it all the way to graduation, and only the best of the best will make the cut - who has what it takes to be the pick of the litter?
