Summary

Westminster does not name or ban any dog breed. Instead, Section 6-7-8 declares an animal 'potentially dangerous' or 'vicious' based on what it actually did, then imposes leash, muzzle, microchip, spay/neuter, and insurance requirements regardless of breed.

Any owner or custodian of an animal shall be criminally liable for any animal's behavior meeting the definition of potentially dangerous animal... (1)Causing bodily injury to any person or domestic animal;(2)Chasing or menacing a person or domestic animal in an aggressive manner;(3)Acting in an aggressive manner while encroaching onto public or private property, from a vehicle, or from the owner's yard through, on or over a fence... The owner of a vicious animal shall maintain at all times either a policy of insurance or a surety bond in a minimum amount of $100,000.00 to cover claims for any personal injuries or property damage inflicted by the vicious animal.

Full Breakdown

Chapter 6-7-8 of the Westminster Municipal Code defines potentially dangerous animals by conduct: causing bodily injury, chasing or menacing aggressively, or acting aggressively while encroaching from a vehicle or the owner's yard. An owner keeping such an animal must be 18 or older, keep it leashed on no more than a six-foot lead outside a proper enclosure, complete a City-approved training or behavior program, have the animal spayed or neutered by a licensed veterinarian, and microchip it with registered owner information. Owners must report an escape within one hour and any attack, sale, transfer, or death of the animal within 24 hours.

00 insurance policy or surety bond with 30 days' notice to the City before any lapse. The Code carves out defenses, including provocation, trespass onto the animal's confined area, and peace-officer use, and none of these classifications turn on the animal's breed.

Violations & Fines

Violating the possession requirements for a potentially dangerous or vicious animal is a criminal offense under Section 1-8-1, W.M.C., punishable by fine or confinement. Failing to notify Animal Management of an escape, attack, sale, or death within the one-hour or 24-hour windows is a separate violation, and courts may order the animal forfeited or euthanized on conviction under Section 6-7-9(E).

Frequently Asked Questions

Does Westminster, Colorado ban pit bulls or any specific dog breed?
No. Section 6-7-8 of the Westminster Municipal Code classifies animals as 'potentially dangerous' or 'vicious' based solely on documented behavior, such as causing injury or menacing aggressively, and never references breed.
What must an owner do once a dog is declared potentially dangerous in Westminster?
The owner must be an adult, restrain the dog outside its enclosure on a lead no longer than six feet, complete an Animal Management Officer-approved training program, have the dog spayed or neutered, microchip it, and report any escape within one hour and any attack, transfer, or death within 24 hours.
What extra requirement applies once a dog is classified vicious rather than potentially dangerous?
A vicious animal must be muzzled and kept on a lead no longer than four feet outside its enclosure, and the owner must carry a $100,000.00 insurance policy or surety bond covering injuries or property damage, with the insurer required to give the City 30 days' notice before any cancellation.
