Owners and Keepers Are Strictly Liable in Utah
Utah is a strict liability state, and the statute covers keepers as well as owners.
The statute
UCA 18-1-1 provides that an individual who owns or keeps a dog is liable for an injury caused by the dog, regardless of whether the dog is vicious or mischievous, or whether the owner knows it is. The official chapter text is on the Legislature's site.
No one-bite rule
One legal blog explains that Utah does not follow a "one free bite" rule; you do not need proof of an earlier bite or of the owner's knowledge.
Damages follow comparative fault
The statute says damages are determined under UCA 78B-5-818, so your own fault can reduce them.
Several dogs
If two or more dogs acting together are owned or kept by different people, they may be sued in one action, and the damages are apportioned among them with several judgments.
Deadline
Dog injury claims are personal injury claims, generally under the four-year period in UCA 78B-2-307.
A local personal injury attorney can review your claim — many offer a free consultation.
