　　He may not have an "S" across his chest but this dog is most certainly a hero.

　　Harley, who was rescued from a puppy mill four years ago, was named the American Humane Association's 2015 American Hero Dog. Harley, who is missing an eye and has other medical issues from his time at the mill, is now a "spokes-dog" against puppy mills. He serves as the adorable furry face of the "Harley to the Rescue" campaign, which raises funds for the National Dog Mill Rescue, according to a press release.

The pup was rescued back in 2011 and adopted by Rudi and her husband, Dan. "It was just four years ago that he was pulled from the cage in the puppy mill and left to die," Harley's owner, Rudi, said during the awards show at the Beverly Hilton Hotel in Los Angeles this past weekend, according to Today. com. "We never would have ever thought he would live this long and make such a difference for so many puppies."
