Colorado Closes the Door on the Puppy Mill Pipeline

Governor Jared Polis signed the Pistol the Pomeranian Protection Act into law, ending the sale of dogs and cats through pet stores and third-party sellers across Colorado. When the law takes effect in January 2028, the state joins New York and California in cutting off the commercial breeding pipeline that has long supplied retailers with animals bred in conditions that prioritize profit over welfare. The legislation addresses a specific cruelty: puppies and kittens trucked into Colorado from out-of-state breeding operations—known as puppy mills—where hundreds of animals live in overcrowded, unsanitary cages. In these facilities, dogs are bred repeatedly while suffering inadequate care. Disease follows. Behavioral problems emerge. Some animals die. Consumers unknowingly purchase sick pets and face steep veterinary bills in return. Coloradans who want a new pet can still work directly with responsible breeders or adopt from shelters and rescues. The law simply removes the mechanism through which commercial breeding operations have profited from the state's consumers. The bill had support from House Majority Leader Monica Duran, Representative Karen McCormick, Senate Majority Leader Robert Rodriguez, and Senator Dylan Roberts. Governor Polis signed it swiftly, reflecting what the ASPCA described as the deep compassion Coloradans hold for animals. The law's passage marks a turning point. Each state that closes this pathway weakens the entire system that depends on retail sales to move animals from mills into homes.
