America's largest chain of puppy-selling pet stores, Petland Inc., is also the nation's largest retail supporter of puppy mills. There are more than 200 Petland stores worldwide, with about 140 in the U.S. Collectively, these stores sell tens of thousands of puppies each year. On November 20, 2008 The Humane Society of the United States (The HSUS) revealed the results of a shocking eight-month investigation of Petland stores. The investigation reveals that Petland stores across the country have marketed puppy-mill puppies to unsuspecting consumers.
