Michael Goessling stops to pet a cocker spaniel while walking Thumbelina, left, a five year old dwarf miniature horse, around the pasture at Goose Creek Farms in St. Louis, MO on Friday, Oct. 3, 2006. At 17.5 inches, Thumbelina is the smallest living horse in the world, and holds the record for the smallest horse in history. Goessling said she often spends more time with the dogs on the farm than the other horses because they are closer to her size. (AP Photo/Sarah Conard)
