Littleton, CO Animal Ordinances: Breed Restrictions (2026)

Littleton's dangerous-animal law in Section 6-2-5 is written around conduct, not breed: it declares any animal exhibiting behavior set forth in this section dangerous, without naming or excluding any breed anywhere in the text. An owner or custodian violates the section if their animal, without intentional provocation, causes bodily injury or death to a person anywhere in the city, approaches a person in a menacing or terrorizing manner or in an apparent attitude of attack while off the owner's property, kills another animal off the owner's property, or attacks a person lawfully on the owner's own property.

It is an affirmative defense if the victim made an unlawful entry onto the owner's property or was attacked while committing a crime against the owner. Once cited, Section 6-2-5(B) bars the animal from public streets, sidewalks, parks or any public place unless it is muzzled and held on a leash by an able-bodied person, and even on private property it must be muzzled and leashed or kept securely confined indoors or in a locked pen with secure sides embedded at least one foot into the ground.

Section 6-2-5(C) lets the animal control officer impound the animal at discretion, or immediately, if it poses a clear and present danger. The Municipal Judge may order destruction on conviction if the animal is found to be a clear and present danger; a second conviction involving the same animal creates a rebuttable presumption of that danger, and a third conviction requires a destruction order.
