Puppy raisers care for guide dog pups in their homes for about a year before the dogs begin formal guide dog training. Guide Dogs is currently seeking more volunteers, with 100 puppy raisers needed each month to meet demand. Steve McLean, general manager at the National Museum of Flight, said: "We want everyone who comes to the National Museum of Flight to enjoy their time with us and make the most of their visit. "Guide Dogs make this possible for many of our visitors. "We were delighted to welcome the puppies to the museum as part of their early training - it's clear to see they are all jet set for success."
