Iowa Attorney General Tom Miller filed a lawsuit Monday to shut down an alleged puppy-laundering ring, involving two "pet rescue" nonprofits accused of exporting designer dogs from Iowa to pet shops in other states.The lawsuit alleges that one of the nonprofits, Hobo K9 Rescue of Britt, sold at least 1,290 puppies to eight entities in California, Illinois, Florida and New Jersey from September 2016 to July 2018.The puppies, including Pomeranians, shar-peis, Alaskan malamutes, poodle-Yorkies and other breeds, were allegedly sold for $714,510.Puppy laundering is the practice of using nonprofit rescue groups to obscure the source of dogs, deceive consumers and circumvent "puppy mill" bans."No matter where they live, consumers should not be misled about the source of the pets they buy," Miller said. "Puppy laundering obscures the identity of breeders who may have animal welfare violations or other problems."
