This article is written for education and clarity, not legal advice. Every situation is different. But having a clear roadmap can help you feel more grounded during an unsettling time.
Colorado Dog Bite Law and Strict Liability: What It Means in Plain English
Colorado follows a strict liability approach to many dog bite cases. That phrase sounds intimidating, but the idea behind it is fairly straightforward.
Under Colorado Revised Statutes § 13-21-124, a dog owner can be held legally responsible if their dog bites someone, even if the dog has never bitten anyone before and even if the owner did nothing “wrong” in the traditional sense.
In other words, Colorado law focuses less on the dog’s past behavior and more on the harm caused.
Why Strict Liability Exists
Strict liability laws exist because dog bites are often sudden and severe, and victims usually have little control over the situation. From a public policy standpoint, Colorado lawmakers have decided that:
- Dog owners are in the best position to prevent bites
- Bite victims should not have to prove a history of aggression
- Medical and financial consequences should not fall solely on the injured person
This approach helps streamline claims and reduces the burden on people already dealing with physical and emotional injuries.

When Strict Liability Applies Under Colorado Law
Strict liability does not apply in every dog-related injury. For a claim to fall under Colorado’s strict liability statute, several conditions generally must be met:
1. The Injury Must Be a “Serious Bodily Injury”
Colorado’s strict liability statute applies only when the dog bite results in a serious bodily injury.
Under Colorado law, this usually means injuries that involve:
- Broken bones
- Significant disfigurement or scarring
- Damage to muscles, tendons, or nerves
- Injuries requiring surgery or extensive medical treatment
Minor bites or superficial wounds may still be compensable, but they are often handled under negligence principles instead of strict liability.
2. The Victim Must Be Lawfully on the Property
Strict liability generally applies when the injured person was:
- On public property (sidewalks, parks, trails) or
- Lawfully on private property (invited guests, delivery drivers, utility workers)
If someone was trespassing at the time of the bite, strict liability usually does not apply.
3. The Bite Must Be From a Dog
The statute applies specifically to dogs, not other animals. Injuries caused by other pets or livestock are handled under different legal standards.
Important Exceptions to Colorado’s Dog Bite Strict Liability Rule
While Colorado dog bite law strict liability is powerful, it is not absolute. Several important exceptions can limit or eliminate an owner’s responsibility.
Provocation
If the injured person provoked the dog, strict liability may not apply. Provocation can include:
- Hitting or kicking the dog
- Teasing or tormenting it
- Pulling ears or tail
- Interfering with puppies or food
That said, provocation is often disputed. A dog owner may claim provocation even when the injured person did nothing unreasonable. These cases often come down to evidence, witness statements, and medical documentation.
Trespassing
If the bite occurred while the injured person was unlawfully on private property, strict liability generally does not apply. However, there can be gray areas—especially when property boundaries are unclear or when the injured person reasonably believed they were allowed to be there.
Government or Military Dogs
Police or military dogs acting in the course of their official duties are typically exempt from strict liability rules, provided the handler followed proper procedures.
What About Dog Bites That Don’t Meet the “Serious Injury” Threshold?
Not all dog bites cause broken bones or require surgery—but that doesn’t mean the injury isn’t serious to the person experiencing it.
When a bite doesn’t qualify as a “serious bodily injury,” a claim may still be brought under negligence law. In those cases, the injured person generally must show that the dog owner failed to act reasonably, such as by:
- Letting a dog roam off-leash in violation of local ordinances
- Failing to restrain a dog known to be aggressive
- Ignoring leash laws or fencing requirements
Negligence cases can be more complex, which is one reason many people choose to speak with a dog bite lawyer to understand which legal path applies to their situation.

The Medical Side of Dog Bites: Why Immediate Care Matters
Legal questions often come later. In the moment, what matters most is your health.
From a medical perspective, dog bites are treated as high-risk wounds, even when they look small. Registered nurses and wound-care specialists emphasize that prompt treatment isn’t just about pain relief—it’s about preventing serious complications.
Why Dog Bites Are Medically Dangerous
A dog’s mouth contains bacteria that can easily be pushed deep into tissue during a bite. This can lead to:
- Infections
- Abscess formation
- Delayed healing
- Nerve damage
Hands, face, and lower legs are particularly vulnerable.
RN-Guided Steps to Take After a Dog Bite
While every injury is different, wound-care professionals generally recommend the following steps:
1. Stop the Bleeding Safely
Apply gentle pressure with a clean cloth or bandage. If bleeding is heavy or won’t stop, seek emergency care immediately.
2. Clean the Wound Thoroughly
If you’re able, rinse the wound with clean running water for several minutes. This helps flush out bacteria. Avoid harsh scrubbing, which can damage tissue.
3. Do Not Seal the Wound Prematurely
Many people instinctively want to close a bite wound with adhesive bandages. In some cases, especially puncture wounds, this can trap bacteria inside. Medical professionals often prefer to leave certain bite wounds open initially.
4. Seek Medical Evaluation Promptly
Even if the bite seems minor, a healthcare provider should evaluate it. They can:
- Assess infection risk
- Determine whether stitches are appropriate
- Prescribe antibiotics if needed
- Evaluate for nerve or tendon damage
5. Ask About Tetanus and Rabies Considerations
Depending on your vaccination history and the dog’s status, additional preventive care may be necessary. Medical providers routinely assess these risks.
Documentation: A Step That Helps Both Health and Legal Claims
From both a medical and legal standpoint, documentation matters.
If you seek care:
- Follow all treatment recommendations
- Attend follow-up appointments
- Photograph the wound over time
- Keep copies of medical records and bills
These records help medical professionals track healing and can later help demonstrate the seriousness of the injury if a legal claim becomes necessary.
An Overlooked Legal Insight: Scarring Is Not Just Cosmetic
One often-overlooked aspect of dog bite cases is scarring, particularly when bites occur on the face, arms, or hands.
Under Colorado law, permanent scarring can qualify as serious bodily injury, even if the initial wound didn’t seem severe. From a human perspective, scars can affect:
- Self-confidence
- Employment opportunities
- Emotional well-being
Medical documentation from wound-care specialists, plastic surgeons, or dermatology providers can play a key role in accurately reflecting the long-term impact of a dog bite.
Real-World Scenario (Based on Common Patterns, Not a Specific Case)
Imagine a Durango resident bitten while visiting a neighbor’s home. The dog had never bitten anyone before. The injury required stitches and later left a visible scar on the forearm.
The owner insists, “My dog’s never done this before.” Under Colorado dog bite law strict liability, that history may not matter if the injury qualifies as serious and the visitor was lawfully on the property. This is precisely the type of situation strict liability laws were designed to address.
How a Dog Bite Lawyer Can Help Clarify Your Options
Dog bite cases often sit at the intersection of medical evidence, statutory law, and insurance coverage. A knowledgeable dog bite lawyer can help by:
- Explaining whether strict liability or negligence applies
- Communicating with insurance companies
- Reviewing medical records to assess injury severity
- Helping ensure deadlines under Colorado law are met
For residents of Durango and La Plata County, working with someone familiar with local practices and Colorado statutes can add clarity during a stressful time.
