Wyoming follows the "one-bite" rule. To recover from the owner, the victim usually has to show the owner knew or should have known the dog was dangerous.

## Who pays when a dog bites someone in Wyoming?
Every state has a rule for when the owner of a biting dog has to pay for the injuries. The rules fall into three categories.
### Wyoming's rule
**Common-law "one-bite" rule**. The owner is liable only if they KNEW or SHOULD HAVE KNOWN the dog was dangerous — usually because it had bitten or shown aggression before. Without that knowledge, the victim usually has to prove ordinary negligence to recover.
## What you typically have to prove
In a one-bite state, the plaintiff has to prove the owner KNEW or SHOULD HAVE KNOWN the dog had a propensity for aggression — usually by:
- Prior bite or attack on a person or animal
- The dog growling, snapping, or lunging at people
- The dog was bred or trained for guarding/aggression and known to be aggressive
- A prior "dangerous dog" or "vicious dog" determination
Without that showing, the case usually requires proving ordinary negligence — that the owner failed to take reasonable precautions.
## Common defenses
- **Trespasser** — the victim was on the property without permission
- **Provocation** — the victim hit, teased, or otherwise provoked the dog
- **Comparative negligence** — the victim's own carelessness contributed to the bite
- **Veterinarian / professional handler rule** — vets, groomers, and handlers assume some risk of being bitten
- **Police / military dog exception** — dogs used in lawful law-enforcement activities
## What damages can be recovered
- **Medical bills** — including future care for scars and reconstructive surgery
- **Lost wages** — and lost earning capacity if injuries are permanent
- **Pain and suffering**
- **Disfigurement / scarring** — particularly significant for facial injuries to children
- **Emotional distress / PTSD** — common in severe attacks
- **Property damage** — torn clothes, damaged personal items
## Insurance is usually how this gets paid
Most dog-bite claims are paid by the dog owner's homeowner's insurance or renter's insurance — not out of the owner's pocket. Some insurers exclude specific breeds (rottweilers, pit bulls, certain mixes) or refuse to insure dogs with prior bites. Check the policy.
## Reporting requirements
Most Wyoming cities and counties require dog bites to be reported to the local health department or animal control within a short window — typically 24-72 hours — to start the rabies-observation process. Reporting also creates an official record that helps a later civil claim.
## Time limits
Dog-bite claims are personal-injury claims and follow your state's general personal-injury statute of limitations (usually 2-3 years from the bite). Don't wait — evidence disappears quickly and witnesses move.
## What you should do
If you've been bitten in Wyoming: get medical care immediately, take photos of the injuries, get the owner's name and insurance information, file a report with animal control, and call a personal-injury attorney before talking to anyone's insurance company. Most Wyoming dog-bite attorneys offer free consultations and work on contingency.
