Famous U.S. Animals To Honor On Labor Day

From Vetstreet's Melanie Kramer and Shayna Meliker:

This Labor Day, not only do we want to pay homage to the hardworking humans of America, but we also want to celebrate some of the hardest-working animals throughout history.

Take a moment of your holiday to read about these seven horses and dogs who we're honoring for their important contributions to America. You may have heard the tales of the mail-carrying Pony Express horses or Balto, the brave Siberian Husky who delivered medicine to an Alaska town in dire need of it, but there's so much more to learn about other hardworking canines and equines.
