Summary

Arvada declares a dog or other animal "dangerous" by conduct, not breed: causing bodily injury, menacing a person, killing another animal off its owner's property, or attacking someone lawfully on the owner's property. City Code Section 14-51 lets an animal management officer destroy a dangerous animal immediately, without notice, if needed to protect public safety, subject to a narrow unlawful-entry defense.

(a)Any animal exhibiting behavior set forth in this section is hereby declared to be a dangerous animal. It shall be unlawful for any owner or custodian of an animal to permit or allow said animal, without intentional provocation, to:(1)Cause bodily injury to any person at any place within the city;(2)Approach any person in a menacing or terrorizing manner, or in an apparent attitude of attack, while off the owner's or custodian's property;(3)Kill another animal while off the owner's or custodian's property; or(4)Attack any person who is lawfully on the owner's or custodian's property...(d)Nothing in this chapter shall be construed to prevent the animal management officer from taking whatever action is reasonably necessary to protect his person or other members of the public from injury or damage, including immediate destruction of any dangerous animal without notice to the owner or custodian.

Full Breakdown

Section 14-51(a) of the Arvada City Code declares an animal "dangerous" based on what it does, not its breed: causing bodily injury to a person anywhere in the city, approaching a person in a menacing or terrorizing manner or in an apparent attitude of attack while off the owner's property, killing another animal while off the owner's property, or attacking a person lawfully on the owner's own property. 5), so Arvada's ordinance evaluates dogs of every breed under this same conduct-based test rather than listing prohibited breeds.

Frequently Asked Questions

Does Arvada ban pit bulls or other specific dog breeds?
No. Colorado law bars cities from banning dogs by breed, so Arvada Code Section 14-51 declares a dog "dangerous" based on its actions, such as biting someone or attacking another animal off its owner's property, not on its breed. Any breed can be declared dangerous or aggressive under this conduct-based standard.
Can Arvada destroy my dog after a dangerous-animal declaration?
Yes, in an emergency. Section 14-51(d) lets an animal management officer take whatever action is reasonably necessary to protect people, including immediate destruction of a dangerous animal without notice to the owner, when the officer determines it is needed to prevent injury.
Is there a defense to a dangerous-animal charge in Arvada?
Section 14-51(b) provides one affirmative defense: if the person the animal injured had unlawfully entered the owner's dwelling or enclosed property, or was bitten while committing a crime against the owner or custodian, the owner is not liable under this section.
