You have two years from the date of a dog bite to file a lawsuit in Colorado. Miss that deadline, and you lose your right to compensation forever - no exceptions, no extensions, no excuses the court will accept.
But here's what the statute of limitations doesn't tell you: waiting anywhere close to that two-year mark is a terrible strategy that will cost you money.
The dog bite attorneys at Conduit Law have seen too many cases weakened or lost entirely because victims waited. This guide explains the legal deadlines, the practical realities, and why acting quickly matters more than most people realize.
Colorado's Dog Bite Statute of Limitations: The Basics
Under C.R.S. § 13-80-102, personal injury claims in Colorado - including dog bite cases - must be filed within two years from the date of injury. This applies whether you're pursuing a claim under Colorado's strict liability statute (C.R.S. § 13-21-124) or under general negligence principles.
The clock starts ticking the moment the dog's teeth break your skin. Not when you realize you need surgery. Not when your scar doesn't fade. Not when you finally decide to talk to a lawyer. The date of the bite is day one.
What Happens If You Miss the Deadline?
If you file your lawsuit even one day after the two-year mark, the defendant will file a motion to dismiss, the court will grant it, and your case is over. You'll have no legal recourse, regardless of how severe your injuries were or how clearly the dog owner was at fault.
According to the CDC, approximately 4.5 million dog bites occur annually in the United States. Many victims lose their right to compensation simply because they didn't understand the deadline or assumed they had more time.
Exceptions to the Two-Year Rule
Minor Victims (Under 18)
Children injured by dog bites receive special protection under Colorado law. The statute of limitations is tolled (paused) until the child turns 18. This means:
- A 10-year-old bitten by a dog has until age 20 to file suit
- A 5-year-old has until age 20 to file suit
- A 17-year-old has until age 20 to file suit (at minimum - they get the full two years from turning 18)
However, parents should not wait. Evidence disappears, witnesses forget details, and the dog owner may move or lose their insurance coverage. Filing promptly while the child is still a minor - with a parent or guardian as the legal representative - produces far better outcomes.
Mental Incapacity
If the dog bite victim is mentally incapacitated and unable to manage their own legal affairs, the statute of limitations may be tolled until capacity is restored. This requires documentation from medical professionals.
Discovery Rule (Limited Application)
In rare cases where an injury wasn't immediately apparent, Colorado's discovery rule may apply. The statute of limitations could run from when the injury was discovered or reasonably should have been discovered. However, dog bite injuries are almost always immediately apparent, making this exception rarely applicable.
Why Waiting Is a Losing Strategy
Even though you technically have two years, every month you wait makes your case weaker and less valuable. Here's why:
1. Evidence Disappears
Critical evidence in dog bite cases has a short shelf life:
- Photos of injuries should be taken immediately and during healing
- Witness memories fade within weeks, not years
- Surveillance footage (if the attack was captured) gets overwritten in 30-90 days
- Animal control reports may be harder to obtain as time passes
- Medical records from the attack need immediate preservation
2. The Dog Owner's Situation Changes
Dog owners move, change insurance policies, lose coverage, or declare bankruptcy. A defendant with a $300,000 homeowner's policy today might be uninsured and judgment-proof in 18 months. You can't collect money that doesn't exist.
3. Your Credibility Suffers
Insurance adjusters and juries ask the obvious question: "If this injury was so serious, why did you wait so long to do anything about it?" Delays create doubt about the severity of your injuries and the legitimacy of your claim.
4. Scar Documentation Requires Time
Here's the paradox: you need time for scars to mature (12-18 months) to know their final appearance, but you also need to document the healing process throughout. Starting your case early allows your attorney to systematically photograph and document scar progression - evidence that becomes impossible to recreate if you wait.
The Insurance Claim vs. Lawsuit Timeline
Many people confuse the insurance claim process with the lawsuit filing deadline. They're separate:
| Action | Deadline |
|---|---|
| Report to homeowner's insurance | ASAP (no fixed deadline, but delays hurt your claim) |
| File animal control report | ASAP (required in many jurisdictions) |
| Negotiate insurance settlement | No fixed deadline, but must preserve lawsuit option |
| File lawsuit in court | 2 years from bite date (hard deadline) |
You can negotiate with insurance for months or even over a year, but if negotiations fail, you must file suit before the two-year mark or lose all leverage.

Special Situations Affecting the Timeline
Government-Owned Dogs
If you were bitten by a police dog, animal control dog, or other government-owned animal, different rules apply. Claims against government entities in Colorado require filing a notice of claim within 182 days (about 6 months) under the Colorado Governmental Immunity Act. Miss this notice deadline, and you're barred from suing - even though the general statute of limitations is two years.
Bites on Government Property
If the bite occurred in a public park, government building, or other public property, and you're claiming the government was negligent (poor animal control enforcement, for example), the 182-day notice requirement may apply.
Multiple Responsible Parties
Some dog bite cases involve multiple defendants - the dog owner, a landlord who knew about a dangerous dog, a dog-sitter who lost control of the animal. Each defendant's liability may have different legal theories and potentially different timing considerations.
Frequently Asked Questions
Can I still file a claim if it's been over a year since the dog bite?
Yes, as long as you're within the two-year statute of limitations. However, your case has likely been weakened by the delay. Contact an attorney immediately to assess what evidence can still be preserved and whether your claim remains viable.
Does the statute of limitations apply to insurance claims?
No. The two-year deadline applies to filing a lawsuit in court. Insurance claims have no fixed deadline, but insurers become increasingly skeptical of delayed claims, and you lose negotiating leverage if you can no longer threaten litigation.
What if I didn't know who owned the dog until recently?
Colorado courts have sometimes applied the discovery rule in cases where the defendant's identity wasn't reasonably discoverable. However, this is a narrow exception, and courts expect plaintiffs to make diligent efforts to identify responsible parties. Don't assume this exception will save a late claim.
My child was bitten. When does their deadline expire?
A minor's statute of limitations is tolled until they turn 18, then they have two years (until age 20). However, waiting that long is almost always a mistake. Evidence deteriorates, and childhood scars need documentation during the growth process to maximize compensation.
I was bitten by a stray dog with no identifiable owner. Do I have a case?
Without an identifiable owner, there may be no defendant to sue for the bite itself. However, you might have claims against a landlord who allowed dangerous strays on their property, a business that failed to secure their premises, or a municipality with negligent animal control. An attorney can evaluate potential defendants.
