Colorado enacted a specific dog bite liability statute that provides significantly stronger protection for bite victims than the common law one-bite rule that still governs dog bite claims in many other states. Colorado Revised Statute Section 13-21-124 imposes strict liability on dog owners for bites that occur in public places or in private places where the victim was lawfully present, without requiring any showing that the owner knew the dog was dangerous. Understanding exactly what the Colorado statute requires, who can be held liable beyond the dog's owner, and what the full damages picture looks like in a serious dog bite case is the foundation for pursuing what Colorado law provides.

Colorado's Strict Liability Standard Under CRS 13-21-124

Colorado's dog bite statute establishes owner liability when the dog bites a person who was in a public place or who was lawfully in a private place, regardless of the dog's prior behavior and regardless of the owner's knowledge of any dangerous propensity. The statute's two defenses are that the victim provoked the dog or that the victim was trespassing at the time of the bite. Colorado courts have interpreted provocation narrowly: accidental contact, a child's innocent approach, and simply being in the dog's vicinity does not constitute legal provocation. The trespassing defense is similarly narrow: a mail carrier, delivery driver, or social guest is lawfully present and within the statute's protection.

Landlord Liability in Colorado's Rental Markets

Colorado's significant urban rental markets in Denver, Boulder, Fort Collins, and Colorado Springs produce a specific dog bite liability scenario more commonly than rural settings: the landlord whose tenant's dog bites another tenant, a visitor, or a member of the public. Colorado courts have recognized landlord liability for tenant dog bites when the landlord knew that the tenant kept a dangerous dog and had the ability under the lease to require its removal but failed to act. A landlord who received prior complaints about an aggressive dog from other tenants, who was informed of a prior bite involving the same animal, or who observed the dog's aggressive conduct in common areas has the knowledge and the authority that Colorado courts require for landlord liability to attach.

Damages Available Under Colorado's Dog Bite Statute

Colorado's dog bite statute specifically provides for economic and non-economic damages. Economic damages include all medical expenses for emergency care, wound treatment, plastic surgery, and the psychological treatment that serious attacks frequently require. Lost income during recovery and permanent scarring or disfigurement as a component of non-economic damages are recoverable. For serious facial injuries and injuries to children, the non-economic damages for permanent disfigurement and the psychological impact of the attack, including post-traumatic stress responses that are well-documented in the dog bite trauma literature, frequently represent the largest component of the total claim. The Colorado Legislature's dog bite statute establishes the complete liability framework applicable to Colorado dog bite claims.
