The Centers for Disease Control and Prevention reports that roughly 4.5 million people in the US are bitten by dogs each year. Hundreds of thousands seek medical care, and approximately 300,000-370,000 are treated in emergency departments. Dogs typically give several warnings through body language and vocalization before they bite, so please teach children and pay attention yourself so as not to set up a dog for disaster.

According to the American Veterinary Medical Association, children are the most common victims, particularly among those turning 5 and 9. Dog bite laws in the United States affect the determination of liability in dog bite cases.

These laws vary by state but mostly fall into two categories: strict liability laws and the “one-bite rule.” Under strict liability, a dog owner is held responsible regardless of the dog’s past behavior. Liability for jurisdictions following the “one-bite rule” mainly depends on whether the owner knew or should have known that the dog was dangerous. 

In some instances, liability extends beyond the owner and includes landlords, property owners, or care providers.

Let’s discuss these laws and the role they play in finding out who can be held responsible for a dog attack situation.

Strict Liability States

Several states have legislated harsh dog bite laws that make dog owners legally responsible for any injuries a dog might cause. This law does not take into account whether or not the dog had exhibited aggressive behavior or whether the owner had some suspicion of the dog’s potential for biting.

Following this strict liability framework, the claimant is required to demonstrate that the person in question owned the biting dog or alternatively, had control over the dog. It must also be clearly shown that the dog bit the victim and that the victim was in a place where he or she had a right to remain. The last requirement involves showing that the dog bite caused injury.

The knowledge or ignorance of the dog owner regarding the pet’s history has an immediate bearing on the preliminary defense. Examples of strict liability statutes include California Civil Code Section 3342, Florida Statute Section 767.01, and the Illinois Animal Control Act (510 ILCS 5/16).

Pennsylvania imposes strict liability only for medical expenses under 3 Pa. Cons. Stat. Section 459-502. For recovery of pain and suffering or lost income, it requires negligence or a prior dangerous propensity to be proven.

Colorado applies strict liability only for serious bodily injuries from a bite under 13-21-124 C.R.S. If the injuries are less serious, the plaintiff must prove negligence. The applicable statute in each jurisdiction must be attentively scrutinized.

The One-Bite Rule

According to New Haven dog bite attorney R.J. Weber III, dog owners are typically held strictly liable for a dog bite victim’s damages, including medical expenses and pain and suffering. Compensation for this case is often covered by property liability insurance.

States that perpetuate the common law one-bite rule, including Texas and Virginia, think that owners are not at fault unless they knew or ought to have known their dog had the propensity to bite someone before a bite occurred.

A dog does not automatically obtain one free bite under the one-bite rule. Owners could be liable for the first bite if they were warned of their dog’s dangerous tendencies by the manifestation of physical signs like growling, snapping, or lunging. 

Pre-bite actions are the main proof of potentially dangerous behavior, but additional factors may be evaluated based on the specific state laws, as summarized by Justia regarding dog-bite legislation in all 50 states.

In areas applying the one-bite doctrine, the burden lies on victims to show that the owner knew or should have known about the dog’s dangerous behavior. This requirement increases the factual intensity of these cases and makes them harder for victims to plead than cases of absolute liability under state law.

Common Defenses

Provocation is the most frequently asserted defense. In quite a few states, partial or full liability can be abolished, reduced, or lessened if a dog-bite victim was being mean, hitting, or calling the dog suddenly to bite. The litigation of these types of cases depends on the law of the state and other boundaries.

A fine distinction is drawn between “intentional provocation” and what may be just accidental behavior (“sudden,” as the court often refers to) that is calculated to provoke a dog.

Strict liability doctrines would normally apply if the injured party were lawfully on the owner’s property as a guest, a contractor, or for other business reasons. If trespassing occurred at the time of the bite, the victim is deemed to be at fault, limiting their recovery.

Apportionment allows a court to allocate damages to one of two parties, the victim or the dog owner, based on the contribution of either party toward the incident.

In a judicial system applying modified comparative negligence, a plaintiff whose negligence exceeds a given percentage may be declared unfit to claim damages. In a pure comparative negligence state, the percentage of fault carried by the victim reduces the recovery amount.

Landlord and Property Owner Liability

It is not always the case that the liability of a dog bite lies entirely with the owner of the dog. In certain instances, landlords and property owners can be held accountable when a tenant’s dog bites someone on or near the rented premises. 

The rule to hold landlords responsible in dog bite cases is more based on what they knew rather than on traditional strict law. A landlord could be found responsible if they actually knew the dog was dangerous, were under the impression of such information since it was given to them, or should have known in certain cases.

In Nolo’s analysis of landlord liability in dog bite cases, the courts of several states would find liability against the landlord in situations where written complaints to a landlord had been raised by neighbors, aggressive behavior was witnessed, or a landlord allowed a dog with an established bite record to live on its property 

Insurance Coverage and Damages

Homeowner and renter insurance policies often provide coverage for dog bite injuries under their personal liability provisions. Most insurance policies in the United States typically limit coverage for damages caused by dogs in the range of $100,000 to $300,000. In compliance with certain breeds, some insurance companies exclude coverage for dog attacks or impose a rider.

The Insurance Information Institute’s Spotlight on Dog Bite Liability for 2025 reported that insurance companies paid out $1.56 billion in total for dog bites and other injuries suffered from a dog during the year. If the policy limits are reached, the dog owner may be made to pay out any remaining amounts.

Injuries from dog bites can lead to claims for medical bills, lost earnings, the cost of future treatments, pain, suffering, mental anguish, and disfigurement. In some states, courts can award punitive damages for failing to terminate the dog or for causing multiple bite attacks.

Statutes of Limitations

Each state has a unique set of statutes of limitation regarding dog bite claims, which usually range between one and three years from the date of injury. In California, under Civil Procedure Code Section 335.1, the deadline is two years. New York allows three years under CPLR Section 214. 

Any instance of missing the deadline will create a permanent barrier that prevents all possibilities of recovery from the subject claim. The state law of the jurisdiction will determine whether a tolling provision exists as an exception to this rule.
