Governor Jared Polis signed a law on Wednesday, April 29, 2026 [1], banning Colorado pet stores from selling dogs and cats.
The legislation targets the commercial sale of pets to dismantle the "puppy mill pipeline" and redirect potential owners toward animal shelters. By reducing the demand for animals from large-scale breeding operations, the state aims to improve animal welfare standards and lower the number of pets in rescue systems [3, 4].
House Bill 26-1011 prohibits pet stores from selling, leasing, or transferring the ownership of dogs and cats [1, 2]. While the commercial sale of these animals is now forbidden, the law allows pet stores to continue hosting adoption events for shelter animals [1, 2].
There is conflicting information regarding when the ban begins. Some reports said the law will take effect in 2028 [2, 4], while other sources said the ban will start next year [4].
The move has drawn mixed reactions across the state. Supporters of the bill said the ban is a necessary step to stop the exploitation of breeding animals. Conversely, some store owners said they are concerned over the economic impact of the restriction on their business models [4].
This legislation makes Colorado one of the few U.S. states to implement a comprehensive ban on the retail sale of dogs and cats in pet stores. The law focuses specifically on the point of sale at retail locations rather than banning breeding entirely [3].
“The legislation targets the commercial sale of pets to dismantle the 'puppy mill pipeline.'”
This law shifts the legal framework of pet ownership in Colorado by decoupling retail commerce from animal acquisition. By removing the convenience of pet stores, the state is forcing a market shift toward non-profit shelters and private rescues, which may lead to a decrease in the profitability of commercial breeding facilities across the region.
