This photo released by Anthony M. Tortoriello shows Faith, a two-legged dog, walking down Michigan Avenue in Chicago to the wonderment of passers-by. Faith, who had actually lost her two back legs in a mowing accident three years ago, had her front legs surgically transferred to her hind quarters when the constant dragging process began to wear on her. Her owner said the change was necessary, but that Faith misses being able to sit at the computer and type. (Associated Press)
