Health and fitness expert and The Biggest Loser star Jillian Michaels has joined forces with The Humane Society of the United States to encourage consumers to stop supporting puppy mills.

Michaels has been photographed by Don Flood for online and billboard ads, which will appear in malls across America to encourage holiday shoppers to help rescue dogs, by adopting dogs and puppies from animal shelters. Michaels commented 'When I first learned about puppy mills, I was horrified and I knew that I needed to do something. Dogs shouldn't be constantly impregnated, confined and forced to live in their own excrement'.
