The dog bite statute of limitations clock starts on the date of the bite or attack. Dog bite claims follow the personal injury limitations period in most states. Some states have specific dog bite statutes; others apply general negligence principles.

The 4-year deadline in Wyoming applies to the following types of dog bite claims:
If your claim falls outside these categories, a different statute of limitations may apply. An attorney can confirm which deadline governs your specific situation.
Dog bites carry serious infection risks including rabies, MRSA, and Pasteurella. Document all wounds, treatments, and associated costs meticulously.
Get the owner's name, address, and contact information. Identify the dog's breed and vaccination status. Verify whether the dog has bitten before.
File a report with local animal control. This creates an official record, triggers an investigation, and may compel the owner to quarantine or surrender a dangerous dog.
Document bites, lacerations, and bruising immediately. Photograph the location of the attack and any relevant conditions (leash laws, fencing, signage).
Anyone who witnessed the attack or knows about the dog's prior aggressive behavior is a potential witness. The owner's prior knowledge of the dog's danger may be critical.
Dog bite law varies by state — strict liability vs. negligence vs. "one bite" rule — and an attorney can determine which doctrine applies and calculate your filing deadline.

The following exceptions apply in Wyoming:
If you miss the 4-year deadline, the defendant will file a motion to dismiss based on the expired statute of limitations. Courts virtually always grant such motions. Your case will be dismissed with prejudice — meaning permanently — regardless of how strong your evidence is. Always consult an attorney as soon as possible after an injury.

Wyoming's 4-year deadline for dog bite claims is longer than 44 and shorter than 4 of the other jurisdictions. Across all states and D.C., dog bite deadlines range from 1 year to 6 years.
If a city, county, state agency, or other government entity is responsible, you typically must file a Notice of Claim with the agency within a much shorter period — often 60–180 days. Missing this notice requirement can permanently bar your claim even before the main statute of limitations expires. Consult an attorney immediately if any government entity is involved.
Possibly, but it is difficult. You would need to demonstrate that a tolling doctrine applies — such as the discovery rule, minority tolling, or fraudulent concealment. An attorney can evaluate whether any exception extends your deadline. Do not assume your claim is dead until you have spoken with a licensed Wyoming attorney.
