Laws governing dog bites dictate when an owner of a dog or other responsible parties can be sued for the injuries caused by the dog. Dog bite laws differ from state to state. In some states, there is the application of strict liability laws, while other states use knowledge of the behavior of the dog.

In 2024, the U.S. Postal Service reported more than 6,000 dog attacks involving postal employees, up from about 5,800 in 2023. California recorded 701 incidents, followed by Texas with 438 and Ohio with 350. While these figures only involve postal workers, this shows how dog-related injuries remain a significant safety concern.

Understanding state-specific dog bite laws is important when determining potential liability. Let’s take a closer look at dog bite laws and liability. 

Two Very Different Legal Models Govern Dog Bite Cases Nationally

States generally fall into one of two broad categories, though the exact rules within each category still vary considerably.

According to strict liability, an owner of a dog will be liable for a bite no matter whether or not there was any reason for the owner to anticipate a danger from the dog. All that matters is that the victim has suffered an injury. No effort is needed to find evidence of prior incidents or negligence on the part of the owner.

In other jurisdictions, the one-bite rule applies, under which the victim needs to prove that the owner was aware of or ought to have been aware of the dangerous nature of a dog based on some prior biting or violent actions of the dog.

In such cases, the first bite of a dog may cause significantly more difficulties for proving the case than the very same bite would have caused in a strict liability jurisdiction.

Most states tend to take positions intermediate between these two approaches, where strict liability applies in some situations. For example, when a dog bites someone while being unleashed in a public place. Other situations require a different rule, like when a dog bites its owner.

Where the Bite Happens Changes Everything

Location is one of the most consequential facts in almost any dog bite case.

If a dog escapes and attacks someone on the sidewalk outside, the dog may be treated much differently legally than the same dog attacking someone while the person and the dog are both in the backyard of the dog’s owner. 

Strict liability jurisdictions, which require the dog owner to pay if the dog escapes and attacks, tend to apply the one-bite rule only when the dog bites the victim on the owner’s property, meaning the very same attack could require different evidence based on its physical location.

Breed Alone Rarely Determines Liability, But It Can Complicate a Case

There is a common misconception that a particular breed of dog automatically imposes a legal consequence. It does not matter what breed of dog it is. What matters is what that specific dog did and what the owner knows.

In some places, there are specific breed ordinances, but a history of aggression, whether the dog is a specific breed or not, is one of the most straightforward ways to prove knowledge.

A Gastonia dog bite lawyer handling a dangerous dog claim usually focuses on the specific animal's documented history and behavior rather than leaning on breed alone, since breed-based arguments tend to carry far less legal weight than actual evidence of a dog's prior conduct.

Defenses Can Significantly Narrow or Eliminate a Claim

Even in a strict liability state, dog bite claims aren't automatic wins for the injured party. Most states recognize at least two defenses that can reduce or entirely bar recovery.

Provocation is the most common. If the injured person provoked the dog, teasing it, hurting it, or otherwise triggering a defensive response, that conduct can defeat or reduce the claim depending on the state's specific rule. 

Trespassing is the second major defense. Someone injured while unlawfully on the dog owner's property has a much weaker claim than someone attacked in a public space or while lawfully present, and some states eliminate the claim entirely in that circumstance.

What Compensation Typically Covers

An effective dog attack claim should be capable of compensating for both economic and noneconomic injuries. The economic injury would include the costs of medical treatment, which may turn out to be very high, since dog attacks often involve a lot of surgeries and reconstructive procedures.

Noneconomic damages, on the other hand, would cover the compensation for pain and suffering, scars, and mental anguish, which may be substantial in case of children.

The Practical Reality

Whether the applicable legal principle is strict liability or the “one bite rule” will depend on factors that at the time appear to be relatively insignificant: whether the dog was leashed, where the occurrence took place (public or private property), and the knowledge of the owner regarding his or her pet.

The key is understanding which law applies to the situation, as this can determine whether a claim has a valid legal basis.
