Full Breakdown

Section 9.03.060(a) makes it unlawful to own, possess, keep, exercise control over, maintain, harbor, transport or sell a dangerous dog, dangerous cat, dangerous domestic animal or other dangerous animal in the Town of Parker. Parker defines a dangerous dog by conduct, not breed: it is a dog that inflicts bodily or serious bodily injury on or causes the death of a person or domestic animal, is kept in violation of a court order imposing conditions for a dangerous animal, or is trained for or engages in animal fighting under Section 18-9-204, C.R.S.

Subsection (b) separately bans owning an 'at-risk dog,' one that demonstrates tendencies a reasonable person would believe could lead to injury or death, such as repeatedly charging a fence or lead in an apparent attempt to attack, biting or attempting to bite, or aggressively baring teeth, growling and snapping at a person or domestic animal. Subsection (c) lists eleven circumstances, including provocation, a peace officer's lawful use of the dog, or two animals fighting while both are at large, under which an animal is not deemed dangerous or at-risk.

An Animal Welfare Officer may impound a dog under this Section per Section 9.04.010, and a court may deny return of the animal to the owner under Section 9.04.050.

Violations & Fines

A conviction under Section 9.03.060 is punished under the elevated tier in Section 9.07.010(a), alongside cruelty to animals and poisoning: a fine of not more than $999.00, imprisonment in the county jail for not more than one year, or both, at the Municipal Judge's discretion, with an option to order an anger management or other treatment program.

Frequently Asked Questions

Does Parker ban specific dog breeds?
No. Parker Municipal Code § 9.03.060 designates a dog as dangerous or at-risk based on what it has actually done, such as inflicting injury, being subject to a court order, or showing aggressive charging or biting behavior, not on the dog's breed.
What happens if my dog is declared dangerous?
Owning, possessing or harboring a dog once it meets the Section 9.03.060 definition of dangerous or at-risk is itself unlawful, and a conviction can bring a fine up to $999.00, up to one year in county jail, or both under Section 9.07.010(a); the Animal Welfare Officer may also impound the dog.
Is there a defense if my dog was provoked?
Yes. Section 9.03.060(c) lists eleven circumstances where an animal is not deemed dangerous or at-risk despite biting or attacking, including when a person provoked the animal or was engaged in unlawfully entering a vehicle where the animal was kept.
