During Barry's career, he was credited with saving the lives of more than forty people, although this number has sometimes varied over the years. Barry's most famous rescue was that of a young boy. He found the child asleep in a cavern of ice. After warming up the boy's body sufficiently by licking him, he moved the boy about and onto his back and carried the child back to the hospice. The child survived and was returned to his parents, although other sources say that the boy's mother died in the avalanche that trapped the boy. The Museum of Natural History of Bern disputes the legend, attributing it to Peter Scheitlin, an animal psychologist.
