Utah Dog Bite Liability: When an Owner Is Responsible
Short answer: Utah applies strict liability to dog owners under Utah Code §18-1-1 — meaning an owner can be held responsible for a bite even if the dog had never shown aggression before, and even if the owner wasn't otherwise negligent. Unlike some states, Utah has no "one free bite" rule protecting an owner whose dog bites for the first time.
Who this guide is for
Anyone in Utah injured by a dog bite, or a dog owner trying to understand their potential liability.
What "strict liability" actually means here
In a typical negligence claim, you generally need to prove the defendant failed to act reasonably. Strict liability is different: to establish an owner's liability for a dog bite, you generally only need to show three things — the defendant owned or kept the dog, the dog bit or attacked you, and you suffered injury as a result. You don't need to prove the owner was careless, or that they knew the dog had dangerous tendencies.
Why this differs from a "one free bite" approach
Some states apply a rule sometimes called "one free bite," where an owner is only liable if they knew (or should have known) their dog had dangerous tendencies — often based on a prior incident. Utah rejects this approach entirely — a first-time bite is enough to establish liability under the strict liability standard, without needing to show any prior warning signs.
Defenses available to a dog owner
Even under strict liability, Utah law recognizes some defenses that can eliminate or reduce an owner's responsibility, including if the victim was:
- Trespassing on the property at the time
- Provoking the dog
- Committing a crime at the time of the attack
If any of these apply, the owner may avoid liability despite the general strict liability standard — which is why the specific circumstances of the incident matter enormously to how a claim actually plays out.
What you generally need to document
- Photos of the injury, ideally taken soon after the incident
- Medical treatment records
- The circumstances of the incident — where it happened, what you were doing, whether you had any interaction with the dog beforehand
- The dog owner's identity and contact information
- Any witnesses
What a dog bite claim can potentially recover
Beyond medical expenses, dog bite claims can potentially address scarring, disfigurement, and other injury-related damages — and in the tragic case of a fatal attack, dog owners can potentially face a wrongful death claim as well.
Frequently asked questions
Does it matter what breed the dog is? Utah's strict liability statute doesn't generally hinge on breed — liability is based on ownership and the bite itself, not the specific breed of dog involved.
What if the bite happened on the dog owner's own property? Strict liability can still apply on the owner's property, though the trespassing defense specifically becomes relevant if the victim wasn't lawfully present there.
Is there a different deadline for filing a dog bite claim than other personal injury claims? Dog bite claims generally follow Utah's general personal injury statute of limitations, though specific circumstances (like the victim being a minor) can affect the applicable timeline — confirm the specifics for your situation.
