After World War I, the small Spitz dogs came to the attention of the American public when the dogs became popular entertainers in the American circus. In 1917, the Cooper Brothers’ Railroad Circus featured the dogs. A dog named Stout's Pal Pierre was famous for walking a tightrope with the Barnum and Bailey Circus in the 1930s, and also contributing to their popularity, they sold puppies after the show. Due to the popularity of the circus dogs, many of today's American Eskimo Dogs can trace their lineage back to these circus dogs.
