1. That [name of defendant] owned a dog;

2. That the dog bit [name of plaintiff] while [he/she] was in a public place or lawfully on private property;

3. That [name of plaintiff] was harmed; and

4. That [name of defendant]’s dog was a substantial factor in causing [name of plaintiff]’s harm.

Directions for Use

Read the last optional paragraph if there is an issue regarding whether the plaintiff was lawfully on private property when he or she was bitten.

For an instruction on common-law liability based on the defendant’s knowledge of his or her pet’s dangerous propensities, see CACI No. 462, Strict Liability for Injury Caused by Domestic Animal With Dangerous Propensities—Essential Factual Elements.

Sources and Authority

  • Civil Code section 3342(a) provides: “The owner of any dog is liable for the damages suffered by any person who is bitten by the dog while in a public place or lawfully in a private place, including the property of the owner of the dog, regardless of the former viciousness of the dog or the owner’s knowledge of such viciousness. A person is lawfully upon the private property of such owner within the meaning of this section when he is on such property in the performance of any duty imposed upon him by the laws of this state or by the laws or postal regulations of the United States, or when he is on such property upon the invitation, express or implied, of the owner.”
  • This statute creates an exception to the general rule that an owner is not strictly liable for harm caused by a domestic animal absent knowledge of the animal’s vicious propensity. (Hicks v. Sullivan (1932) 122 Cal.App. 635, 639 [10 P.2d 516].)
  • It is not necessary that the skin be broken in order for the statute to apply. (Johnson v. McMahan (1998) 68 Cal.App.4th 173, 176 [80 Cal.Rptr.2d 173].)
  • “The defenses of assumption of the risk and contributory negligence may still be asserted” in an action brought under section 3342. (Johnson, supra, 68 Cal.App.4th at p. 176.)
  • “A veterinarian or a veterinary assistant who accepts employment for the medical treatment of a dog, aware of the risk that any dog, regardless of its previous nature, might bite while being treated, has assumed this risk as part of his or her occupation.” (Nelson v. Hall (1985) 165 Cal.App.3d 709, 715 [211 Cal.Rptr. 668], original italics.)
  • “[Plaintiff], by virtue of the nature of her occupation as a kennel worker, assumed the risk of being bitten or otherwise injured by the dogs under her care and control while in the custody of the commercial kennel where she worked pursuant to a contractual boarding agreement. The Court of Appeal correctly concluded a strict liability cause of action under the dog bite statute (§ 3342) was therefore unavailable to [plaintiff].” (Priebe v. Nelson (2006) 39 Cal.4th 1112, 1132 [47 Cal.Rptr.3d 553, 140 P.3d 848].)
  • The definition of “lawfully upon the private property of such owner” effectively prevents trespassers from obtaining recovery under the Dog Bite Statute. (Fullerton v. Conan (1948) 87 Cal.App.2d 354, 358 [197 P.2d 59].)
