Understanding Colorado Dog Bite Liability Rules
Learn how Colorado’s strict liability and negligence rules apply when a dog bite or attack causes injury or death.
Colorado handles dog bite cases using a mix of strict liability and traditional negligence rules, with special protections and exceptions written into state law. Understanding how these rules interact is essential for both injured people and dog owners.
Key Takeaways About Colorado Dog Bite Law
- Colorado’s main dog bite statute is Colorado Revised Statutes (C.R.S.) § 13-21-124, which creates strict liability in certain cases.
- Owners can be liable for a serious bite even if the dog has never attacked before and had no known history of aggression.
- The statute focuses on serious bodily injury or death and limits recovery under strict liability to economic damages only.
- Victims with less severe injuries, or those seeking pain and suffering, must usually pursue a negligence-based claim.
- Colorado law includes several defenses and exceptions, such as trespassing, provocation, and bites involving working or police dogs.
Strict Liability vs. Negligence: How Colorado Differs From “One-Bite” States
States approach dog bite cases in different ways. Colorado has moved away from the traditional “one-bite” rule that once dominated U.S. law.
| Legal Approach | Basic Idea | How Colorado Uses It |
|---|---|---|
| One-bite rule | Owner generally not liable for a first bite unless they knew or should have known the dog was dangerous. | Colorado largely rejects a pure one-bite rule, especially for serious injuries. |
| Strict liability | Owner can be liable without proof of negligence or prior vicious behavior. | Applied by statute for serious bodily injury or death caused by a dog bite while the victim is lawfully on property. |
| Negligence | Victim must show the owner failed to act with reasonable care, leading to injury. | Used in Colorado for less severe injuries or when the victim seeks non-economic damages like pain and suffering. |

When Strict Liability Applies Under C.R.S. § 13-21-124
Colorado’s strict liability statute gives certain dog bite victims the right to recover economic losses without proving the owner was careless.
Who Can Use the Strict Liability Statute?
Under C.R.S. § 13-21-124, a person (or their personal representative) may file a civil action if all of the following are true:
- The injury was caused by a dog bite.
- The victim was lawfully on public or private property at the time of the bite.
- The bite caused serious bodily injury or death as defined by Colorado law.
When these conditions are met, the owner can be liable even if:
- The dog had never bitten or attacked anyone before.
- The owner had no prior knowledge of aggressive tendencies.
- The owner took reasonable care to control the dog.
What Counts as “Serious Bodily Injury” in Colorado?
The statute incorporates the criminal law definition of serious bodily injury from C.R.S. § 18-1-901(3)(p). Examples include injuries that involve:
- A substantial risk of death.
- A substantial risk of serious permanent disfigurement.
- A substantial risk of long-term loss or impairment of a body part or organ.
- Broken bones or fractures.
- Second- or third-degree burns.
Less severe wounds, such as superficial punctures or minor scratches that do not meet this definition, generally fall outside the strict liability statute and are handled under negligence principles.
Damages Available Under Strict Liability
Colorado limits the remedy available under its strict liability dog bite statute. Victims can recover only economic damages, which typically include:
- Past and future medical and hospital expenses.
- Rehabilitation and physical therapy costs.
- Past and future lost income or diminished earning capacity.
- Reasonable psychological counseling costs.
Strict liability does not allow recovery for non-economic harms such as pain and suffering, emotional distress, or loss of enjoyment of life. To recover those, the victim usually must prove negligence or another fault-based theory.
Negligence Claims for Dog Bites and Dog Attacks
Colorado law also recognizes standard negligence claims alongside the strict liability statute. Negligence becomes especially important in two scenarios:
- The injury from the bite is less than serious under the statutory definition.
- The victim seeks non-economic damages in addition to economic losses.
Elements of a Negligence-Based Dog Bite Case
To prevail on a negligence claim, an injured person typically must prove:
- The owner owed a duty of reasonable care to prevent the dog from causing foreseeable harm.
- The owner breached that duty (for example, by failing to restrain the dog properly).
- The breach caused the injury.
- The victim suffered damages as a result.
Examples of potentially negligent conduct can include:
- Allowing a dog known to be aggressive to roam at large.
- Ignoring local leash laws or failing to secure a fence.
- Failing to act after prior warnings or incidents.
Damages in Negligence Cases
Unlike strict liability claims, negligence-based suits may allow recovery of both:
- Economic damages (medical bills, lost income, etc.).
- Non-economic damages, such as pain and suffering, emotional trauma, or loss of enjoyment of life, subject to Colorado-wide damage caps where applicable.
Who Counts as a “Dog Owner” Under Colorado Law?
Colorado’s dog bite statute uses a broad concept of ownership. It covers anyone who owns, keeps, or has control over the dog, not only the legal owner of record.
Under C.R.S. § 13-21-124, a dog owner can include:
- A person or entity that owns the dog.
- Someone who possesses, harbors, or keeps the dog.
- A person or organization with a property or financial interest in the dog.
- Anyone with control or custody of the dog.
This broad definition helps ensure that the party responsible for managing and controlling the dog can be held accountable for injuries.
Statutory Defenses and Exceptions for Dog Owners
Even when the basic requirements of strict liability are met, Colorado law lists several circumstances where the owner is not liable.
Situations Where the Owner Is Generally Not Liable
According to C.R.S. § 13-21-124(5), a dog owner is not liable under the statute when:
- The injured person was unlawfully on public or private property (trespassing) when the bite occurred.
- The person was on the owner’s property, which was clearly and conspicuously posted with signs such as “no trespassing” or “beware of dog.”
- The dog was being used by police or military personnel performing official duties.
- The injured person knowingly provoked the dog.
- The injured person was a veterinary professional, groomer, humane society staff member, trainer, or dog show judge performing their duties.
- The bite occurred while the dog was working in activities such as hunting, herding, or farming on the owner’s property under certain conditions.
Even if the strict liability statute does not apply, a victim may still attempt to prove a negligence claim depending on the facts. However, these statutory defenses are powerful tools for dog owners in many situations.
Comparative Negligence and Shared Fault
Colorado uses a form of comparative negligence in many personal injury cases, which can also affect dog bite disputes. If a victim’s own conduct contributed to the incident—such as ignoring warnings or provoking the dog—their compensation may be reduced proportionally. When a victim is found at least 50% responsible, they may be barred from recovery entirely under Colorado’s modified comparative negligence rule.
Time Limits: Colorado’s Statute of Limitations for Dog Bites
Dog bite cases are typically treated as personal injury claims and are subject to Colorado’s general personal injury statute of limitations. In many situations, an injured person has two years from the date of the bite to file a lawsuit, although specific time limits can depend on the details of the case and any related claims.
Waiting too long can permanently bar recovery, so injured parties are usually advised to investigate deadlines early.
Practical Steps After a Dog Bite in Colorado
Both victims and owners should take immediate, practical steps after a bite incident.
For Injured People
- Seek medical care promptly to document injuries and prevent infection.
- Identify the dog and owner, noting names, addresses, and contact details.
- Photograph injuries and the scene, including any signage like “beware of dog.”
- Collect witness information, including names and phone numbers.
- Report the incident to local animal control or law enforcement as appropriate.
- Preserve bills and records related to medical treatment, lost work, and other expenses.
For Dog Owners
- Secure the dog to prevent further incidents and comply with local animal control directives.
- Cooperate with medical responders and provide vaccination information if available.
- Notify your homeowner’s or renter’s insurer, as many policies address dog bite liability.
- Document the circumstances, including the victim’s behavior, posted signs, and any prior warnings.
- Consult legal counsel if serious injuries or potential claims are involved.
Local Ordinances and Dangerous Dog Designations
Beyond state law, Colorado cities and counties may enforce local ordinances about leash requirements, confinement, and dangerous or vicious dog designations. Violations of local rules can be evidence of negligence in a civil case and may lead to separate fines or penalties.
State law also allows for criminal and administrative proceedings in certain serious cases, such as when a dog is officially classified as “dangerous” after severe attacks. These proceedings are distinct from civil damages claims but can affect how future incidents are handled.
Frequently Asked Questions About Colorado Dog Bite Law
Q: Does Colorado give every dog “one free bite” before the owner is liable?
A: No. Colorado’s statute imposes strict liability for serious bodily injury or death from a dog bite when the victim is lawfully on property, regardless of prior incidents or the owner’s knowledge of aggression.
Q: What if my injuries are not considered “serious bodily injury”?
A: If your injuries do not meet the statutory definition of serious bodily injury, you generally cannot use the strict liability statute, but you may still pursue a negligence claim to seek compensation.
Q: Can I recover money for pain and suffering from a Colorado dog bite?
A: Pain and suffering and other non-economic damages are not available under the strict liability statute, but they may be recoverable in a negligence-based lawsuit, subject to statewide damage caps.
Q: Are landlords or caretakers ever responsible, or only the dog’s legal owner?
A: Colorado’s statute uses a broad definition of “dog owner,” covering individuals or organizations that own, harbor, keep, or have custody or control of the dog, which can extend beyond the legal owner in some situations.
Q: What if the victim was trespassing or provoking the dog?
A: The statute provides specific defenses where the victim was unlawfully on property, clearly warned off by signage, or knowingly provoking the dog, which can bar or limit strict liability claims.
