Summary

No. Colorado state law bars any county or town from regulating dangerous dogs by breed, so Douglas County has no pit-bull or breed ban. The county instead regulates individual "vicious" dogs by behavior: biting or attacking without provocation.

These county ordinances apply to unincorporated areas of Douglas County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Nothing in this section shall be construed to abrogate a county's authority under part 1 of article 15 of title 30, C.R.S., to adopt dog control and licensing resolutions and to impose the penalties set forth in section 30-15-102, C.R.S.; except that any such resolution shall not regulate dangerous dogs in a manner that is specific to breed.

Full Breakdown

Under C.R.S. §18-9-204.5(5)(b), a county may adopt dog-control resolutions but "such resolution shall not regulate dangerous dogs in a manner that is specific to breed." A parallel rule (5)(a) applies to municipalities. Douglas County's R-998-100 follows this by defining a "vicious dog" (§1.00(16)) by conduct, a dog that bites or attacks a person or domestic animal without provocation, approaches in an attitude of attack in a vicious or terrorizing manner, or is found vicious by a court, not by breed. Failing to keep a vicious dog under physical control is a Class 2 petty offense (§1.05(1)(f)).

Violations & Fines

Owners cannot be cited for a dog's breed. Failing to keep a vicious dog under physical control is a Class 2 petty offense; state dangerous-dog charges under §18-9-204.5 range from a misdemeanor to a felony.
