Dog Bite Defenses: Trespass and Your Own Fault
The statutory exceptions are narrow, and one of them requires a fence.
Trespassers behind a fence
An owner or keeper is not liable if the injury is to a trespasser in violation of Utah Code 76-6-206(2), and it occurs on the owner's private property while the dog is reasonably secured within a fence or other enclosure. Both conditions must be met.
Law enforcement dogs
The state, counties, cities and towns, and peace officers are not liable for injuries by a dog and handler trained and certified for law enforcement, if the statute's conditions are met.
Other animals
An owner is not liable for an injury or death to another animal that entered the private property without consent, while the dog was reasonably secured.
Your own fault
Damages are determined under UCA 78B-5-818, so provoking the dog or other fault reduces them, and 50% or more bars recovery. Law firm summaries list provocation as a defense, but the statute's text lists only the exceptions above.
Insurance
Dog injury claims are often paid under the owner's homeowner's or renter's insurance.
A local personal injury attorney can review your claim — many offer a free consultation.
