 While Petland has claimed that puppies are sourced from family raised breeders, breeders with clean records, and rescues only, reports have been made public published by the Humane Society of the United States reporting that some parts of the chain have purchased dogs from commercial breeding farms selling “over 5,000 puppies a year” and breeders with animal welfare violations.The credibility of these reports is contested.In addition to investigations conducted by The Humane Society of the United States, a past and current class action lawsuit and over 500 negative reviews on ConsumerAffairs.com also state that Petland receives many dogs from puppy mills.
