The American Eskimo Dog is a breed of companion dog, originating in Germany. The American Eskimo Dog is a member of the Spitz family. It is considered an ancient dog breed due to its recent admixture with wolves. The breed's progenitors were German Spitz, but due to anti-German sentiment during the First World War, it was renamed "American Eskimo Dog." Although modern American Eskimo Dogs have been exported as German Spitz Gross (or Mittel, depending on the dog's height), the breeds have diverged and the standards are significantly different. In addition to serving as a watchdog and companion, the American Eskimo Dog also achieved a high degree of popularity in the United States in the 1930s and 1940s as a circus performer.
