Littleton, CO Animal Ordinances: Pet Store Rules (2026)

B(D) of the Unified Land Use Code, adopted by Ordinance 01, Series of 2024, and effective March 15, 2024, bars any pet store from selling, offering for sale, auctioning, bartering, donating, or otherwise transferring a dog or cat, closing off Littleton's version of the retail commercial breeder pipeline. The prohibition carries two narrow carve-outs. First, a pet store may still transfer a dog or cat if the animal came from an animal rescue organization, kennel, or foster individual, but only if the store posts the name of that rescue organization, kennel, or foster individual in a conspicuous spot on the animal's enclosure and keeps documentation proving the animal's source for three years after any sale, available to any local authority enforcing the section.

Second, the ban does not reach a person or business other than a pet store that sells, offers for sale, auctions, barters, donates, or otherwise transfers a dog or cat that was bred and reared on that same person's or business's own premises, which covers small in-home or hobby breeders selling animals they raised themselves. Together the two exceptions mean a Littleton pet store can still carry dogs and cats, but only rescue-sourced or shelter-sourced animals with a documented chain of custody, not animals bought in from commercial breeders or brokers.
