When a Dog Attacks Your Pet or Service Animal in Utah: Liability, Your Rights, and Deadlines
General information, not legal advice. Read the full disclaimer.
Short answer: Utah Code § 18-1-1 makes the owner or keeper of a dog liable for "an injury caused by the dog," regardless of whether the dog is vicious or the owner knew it was. The statute's exception for harm to another animal applies only if the injured animal entered the owner's private property without consent and the injury happened while the dog was reasonably secured within a fence or other enclosure (§ 18-1-1(3)(a)). Separately, § 18-1-3 provides that "any person may injure or kill a dog" while it is attacking, chasing or worrying a domestic animal having a commercial value, a service animal, or hoofed protected wildlife, or attacking domestic fowls, or while the dog is being pursued for doing so. Many claims for injury to personal property have a three-year deadline (§ 78B-2-305), but confirm which deadline applies.
Who this guide is for
Utah pet owners and handlers of service animals whose animal was attacked by someone else's dog, and owners whose dog was accused of attacking.
Owner liability
The dog statute is written broadly: an individual who owns or keeps a dog is liable for an injury the dog causes, subject to the narrow exceptions. The exception for injury to another animal (§ 18-1-1(3)(a)) is limited to an animal that entered the owner's private property without consent, injured while the dog was reasonably secured in a fence or enclosure. That wording suggests the general rule can apply to attacks on animals elsewhere (for example, on a walk or in a park), but how courts value and treat claims for an injured animal is a legal question. Comparative fault applies: a dog walker whose off-leash dog provoked a fight may bear a share. See Utah Dog Bite Liability and Utah's Comparative Fault Rule.
When you may stop an attacking dog
Section 18-1-3 (effective May 3, 2023) lets any person injure or kill a dog while:
- the dog is attacking, chasing or worrying (a) a domestic animal having a commercial value, (b) a service animal, or (c) any species of hoofed protected wildlife;
- the dog is attacking domestic fowls; or
- the dog is being pursued for committing those acts.
Notice the categories. The statute doesn't list a family pet without commercial value, so don't assume it authorizes force against a dog attacking a pet dog or cat. Local ordinances and criminal laws on animal cruelty and weapons may also apply. Call animal control or police if you can, and talk to a lawyer before taking action that could create liability.
Damages and evidence
- Veterinary bills, boarding and medication.
- The animal's value or, for a service animal, replacement and retraining costs and lost use.
- Your own injuries if you were hurt trying to separate the animals. See What to Do After a Dog Bite in Utah.
- Emotional harm is treated differently when the injured subject is an animal; ask a lawyer how Utah courts approach it.
- Evidence: photos of the animal's injuries and the scene, vet records, the other dog's owner's information, witnesses, and animal control reports.
Deadlines
Injury to personal property is subject to a three-year limitation under § 78B-2-305(1)(a)(ii) (version effective March 23, 2026), though other periods can apply to personal injury to you (generally four years under § 78B-2-307(4)). See Utah Personal Injury Statute of Limitations. Small claims court may be an option for modest veterinary bills: see Utah Small Claims Court.
Service animals
A service animal injury can also affect the handler's ability to work and function. Document the animal's training and role, the cost to replace or retrain it, and any disruption. Consult a lawyer about all available claims.
