Pennsylvania Dog Bite Laws Explained (Mixed Statute)
Mixed Statute
Pennsylvania’s Dog Law guarantees your medical costs regardless of fault — but pain and suffering requires a "severe injury" or proof the owner knew the dog was dangerous.
How Pennsylvania Dog Bite Law Works
If a dog bit you in Pennsylvania, there is one thing you are entitled to immediately and one thing you have to establish. Under 3 P.S. § 459-502, the owner or keeper must pay the full cost of medical treatment resulting from the attack — no proof of negligence, no proof the dog had bitten before, no fault analysis. That obligation applies in every bite case.
Everything beyond medical costs is a different question. Pain and suffering, scarring, emotional distress and lost wages require either a 'severe injury' as the Dog Law defines it, or evidence that the owner knew of the dog's dangerous propensities. That split is why Pennsylvania is classified here as a mixed statute rather than a strict liability state, and it is the single most important thing to understand about what a Pennsylvania claim is worth.
The definition of severe injury is specific rather than impressionistic: any physical injury resulting in broken bones, or disfiguring lacerations requiring multiple sutures or cosmetic surgery. Because it is specific, the medical record does unusual work. Whether a wound required multiple sutures and whether it was characterised as disfiguring are documented facts that determine which damages are even available.
One thing has recently become easier. A 2024 amendment removed the prior-propensity requirement from Pennsylvania's dangerous dog provisions, so a first attack causing severe injury can now support a dangerous dog determination. The old problem — a serious first attack falling outside the framework built to address exactly that harm — has been addressed.
Where a Pennsylvania attorney earns their fee is usually in two places: making sure the medical documentation accurately reflects the severity and permanence of the injury, since that determines the category of the claim, and pursuing the propensity evidence that provides the alternative route where the severe injury threshold is not met.
Fees are contingency, nothing upfront, commonly around a third of any recovery, and typically nothing owed if there is no recovery. Pennsylvania requires a written contingent fee agreement, so the terms should be in front of you before anything is signed.
Not every bite needs a lawyer. A minor wound with medical costs the owner is paying and no lasting mark can be handled directly. What changes it: any injury near the severe-injury line, a child victim, permanent scarring, a denied claim, an owner refusing to pay medical costs the Dog Law requires them to pay, or any involvement of a Commonwealth or local agency, because of the six-month notice deadline.
The evidence that decides a Pennsylvania claim: the complete medical record with particular attention to how the wound closure and any scarring were described, photographs of the injury immediately and through healing, any prior dangerous dog determination or complaints against the dog, the owner's name and insurance details, and the reports filed with both animal control and the health department.

The Pennsylvania Dog Law Covers Medical Costs — Automatically
Under 3 P.S. § 459-502, the owner or keeper of a dog that attacks or bites someone must pay the full cost of medical treatment resulting from the attack. No proof of negligence, no proof the dog had bitten before, no fault analysis.
This is the part of Pennsylvania law that is genuinely strict liability, and it is worth knowing about immediately because many people never learn it. The Dog Law obligation to pay medical costs applies in every bite case. It does not depend on the dog's history, the owner's knowledge, or who was to blame.
It is a floor rather than a ceiling. Meeting it does not resolve a claim, and an owner or insurer who offers to cover the emergency room bill has done what the statute already required rather than made a settlement offer. Understanding that distinction is often the difference between accepting a first offer and recognising it as a starting point.
Everything Beyond Medical Costs Requires More
Pain and suffering, scarring, emotional distress and lost wages are not covered by the Dog Law’s medical-costs provision. Recovering them requires proving either a "severe injury" or that the owner knew of the dog’s dangerous propensities.
This split is why Pennsylvania sits in the mixed-statute category rather than with the strict liability states, and it is the single most important thing to understand about a Pennsylvania claim's value. Two people with visually similar injuries can end up in very different positions depending on which side of the line their case falls.
The two routes to full damages operate independently. A severe injury opens the door on its own. So does evidence the owner knew the dog was dangerous — prior complaints, an earlier attack, the dog kept muzzled or chained, a previous dangerous dog determination. Where both are absent, a claim may recover its medical costs and comparatively little else.
What Counts as a "Severe Injury" in Pennsylvania
The Dog Law defines severe injury as any physical injury that results in broken bones or disfiguring lacerations requiring multiple sutures or cosmetic surgery. That definition is frequently the line between medical costs alone and full damages.
Because the definition is specific rather than impressionistic, the medical record does unusual work in a Pennsylvania case. Whether a wound required multiple sutures, whether it was characterised as disfiguring, whether cosmetic or reconstructive surgery was recommended — these are documented facts that determine which damages are available.
The practical consequence is that how a treating physician writes up a wound closure matters more in Pennsylvania than in a strict liability state, where the same record would only affect the size of an award rather than its availability. It is also a reason not to minimise an injury when describing it to a clinician.
The 2024 Amendment Removed the Prior-Propensity Requirement
A 2024 amendment to Pennsylvania’s dangerous dog provisions removed the requirement that a dog have shown dangerous propensities before an attack. A first attack causing severe injury can now support a dangerous dog determination.
Before the amendment, a dangerous dog determination generally required evidence that the dog had a history — which produced the familiar problem of a serious first attack falling outside the framework designed to address exactly that harm.
The change matters for the civil claim because a dangerous dog determination is one of the routes to damages beyond medical costs, and because a determination carries its own ongoing obligations for the owner: registration, confinement, insurance and posting requirements administered by the Pennsylvania Department of Agriculture's Dog Law Enforcement Office.
The Confinement Requirement and Negligence Per Se
The Dog Law separately requires owners to keep dogs confined, firmly secured, or under reasonable control at all times. Pennsylvania courts have treated a violation as negligence per se — which can establish the negligence half of a claim without proving anything about the dog’s history.
This provision is frequently the most useful part of the Dog Law for someone whose injury is not 'severe' and whose dog had no prior history. The statute obliges an owner to keep a dog confined within the premises, secured by a collar and chain or other device so it cannot stray, or under the reasonable control of some person. A dog that was simply loose was, by definition, not being kept that way.
Pennsylvania courts have held that violating the confinement requirement can constitute negligence per se, meaning the breach element is established by the violation itself rather than argued from scratch. That matters because negligence is one of the two routes to damages beyond medical costs, and this route does not require showing the owner knew the dog was dangerous.
The practical instruction follows directly. Where the dog was loose, off-leash, or had escaped a yard, that fact is worth documenting immediately — photographs of an open gate, a failed latch, a gap in fencing, and any animal control record of the dog being at large. In a case that would otherwise be confined to medical costs, it can be the difference.
Comparative Negligence and the 51% Bar
Pennsylvania applies modified comparative negligence under 42 Pa.C.S. § 7102. Damages drop by your share of fault and recovery is barred once your fault exceeds the defendant’s — but the medical-costs obligation operates separately.
The interaction between the two halves of a Pennsylvania claim is worth being precise about. Comparative fault applies to the negligence claim, where pain and suffering lives. The Dog Law's requirement that the owner pay medical costs is a statutory obligation that does not turn on fault at all.
That means a claimant with a significant fault problem may still be entitled to have their medical treatment paid for even where the negligence claim is compromised. It is not a common point of emphasis, and it is one an unrepresented claimant is unlikely to raise on their own.
Pennsylvania Preempts Breed-Specific Legislation
3 P.S. § 459-507-A bars local governments from regulating dogs in a breed-specific manner. No Pennsylvania municipality may ban or restrict a dog by breed, and breed plays no role in liability.
The statewide preemption puts Pennsylvania with California, Arizona, New York and Nevada rather than with Missouri, Michigan and Ohio, where local breed ordinances remain in force. A Pennsylvania dangerous dog determination turns on the individual animal's conduct.
Insurance underwriting remains outside the preemption's reach. Pennsylvania does not prevent carriers from excluding particular breeds from homeowners coverage, which occasionally determines whether a policy responds at all.
Landlord Liability in Pennsylvania
A Pennsylvania landlord may be liable where they knew of a tenant’s dog’s dangerous propensities and retained control sufficient to have the animal removed. The Dog Law’s medical-costs provision reaches the owner or keeper rather than a landlord as such.
Pennsylvania courts have permitted claims against landlords who had actual knowledge of a dangerous dog on the premises and the contractual ability to require its removal but permitted it to remain. Prior written complaints are the usual proof, and common areas produce the strongest claims.
Note the statutory limit: § 459-502 imposes the medical-costs obligation on the owner or keeper of the dog. A landlord who is neither is answerable, if at all, through ordinary negligence rather than through the Dog Law.
Wrongful Death and Survival Actions
A fatal attack supports both a wrongful death action for the family’s losses and a survival action for the decedent’s own damages. Both run two years from the date of death under 42 Pa.C.S. § 5524.
Pennsylvania distinguishes the two claims more clearly than many states. The wrongful death action compensates the statutory beneficiaries for their losses, including funeral and medical expenses and the value of the services and companionship they lost. The survival action belongs to the estate and covers the decedent's own pain and suffering and lost future earnings.
Both are ordinarily brought together by the personal representative. The two-year period runs from the date of death, which is not necessarily the date of the attack.
Uninsured Owners and Philadelphia’s Enforcement Layer
Most claims are paid from a homeowners or renters policy. Philadelphia adds a municipal enforcement layer, with fines available against owners separately from any civil claim.
Where no policy exists, the Dog Law's medical-costs obligation still attaches to the owner personally, but collection becomes the practical question and a judgment is only worth what the defendant has. Standalone animal-liability and umbrella policies are worth identifying before concluding there is no coverage.
Philadelphia enforcement runs through the Animal Care and Control Team, with the Department of Public Health's Division of Disease Control handling the exposure and rabies side. Those are two separate reporting routes, and a claim is better documented with both on file — particularly given that in Pennsylvania the medical record is what determines which damages are available at all.
Deadlines, Minors, and Government Defendants
Two years from the date of the bite under 42 Pa.C.S. § 5524, tolled during minority by § 5533(b). A claim against a Commonwealth or local agency requires written notice within six months under § 5522.
The two-year period is shorter than New York's three or North Carolina's three, and it applies to the negligence claim, the wrongful death claim and the survival action alike. For a minor, § 5533(b) tolls the period until the child turns eighteen.
The six-month notice requirement under § 5522 is the deadline that quietly ends claims. It applies where a Commonwealth or local agency is involved — a police K-9, a bite on government property, an agency-owned animal — and it runs well before anyone is thinking about a lawsuit. Sovereign and governmental immunity under 42 Pa.C.S. §§ 8521–8564 also caps what can be recovered from a public defendant.
Red means the owner's insurer can use it against you. Green means Pennsylvania has closed that argument off.
| Defense | Status | How it works in Pennsylvania |
|---|---|---|
| Injury not "severe" and no known propensity | Available | The defining limit of a Pennsylvania claim. Without a severe injury or proof the owner knew the dog was dangerous, recovery is generally confined to medical costs under § 459-502 — no pain and suffering. |
| Provocation | Available | A dangerous dog determination under § 459-502-A requires that the attack was unprovoked, so provocation blocks that route and feeds into comparative fault under 42 Pa.C.S. § 7102. |
| Trespassing | Available | Pennsylvania premises-liability principles limit the duty owed to a trespasser, and unlawful presence undercuts the negligence half of the claim. |
| Comparative fault above 50% | Available | 42 Pa.C.S. § 7102 bars recovery where your fault exceeds the defendant's. |
| "The dog had never bitten before" | Limited | Weaker than it used to be. A 2024 amendment removed the prior-propensity requirement from the dangerous dog provisions, so a first attack causing severe injury can support a determination. |
| Refusing to pay medical costs | Not a defense | Not available. The Dog Law obligation to pay the victim's medical costs applies regardless of the owner's knowledge, the dog's history, or fault. |
| Breed of the dog | Not a defense | 3 P.S. § 459-507-A preempts breed-specific local regulation across Pennsylvania. |
Modified comparative negligence (51% bar). Damages drop by your share of fault, and recovery is barred once your fault exceeds the defendant's. Note the interaction: comparative fault applies to the negligence half of a Pennsylvania claim, while the statutory obligation to pay medical costs under the Dog Law operates separately.
Example: on a claim otherwise worth $100,000, being found 30% responsible would typically leave about $70,000 — but at 51% or more, Pennsylvania law bars recovery entirely.
Statute of Limitations in Pennsylvania
Pennsylvania gives two years from the date of the bite under 42 Pa.C.S. § 5524 — shorter than New York's three or North Carolina's three, and the same period applies to a wrongful death action and a survival action, both measured from the date of death. For a minor, § 5533(b) tolls the limitations period during minority, so the two years generally begins when the child turns 18. The deadline that quietly ends Pennsylvania claims is the government one. Where a Commonwealth or local agency is involved — a police K-9, a bite on government property, an agency-owned animal — 42 Pa.C.S. § 5522 requires written notice within six months of the incident, long before most people are thinking about litigation. Sovereign and governmental immunity under 42 Pa.C.S. §§ 8521 through 8564 also limits both what claims may be brought against a public defendant and what can be recovered. One further point specific to Pennsylvania's structure: the Dog Law obligation to pay medical costs is a statutory duty on the owner, but pursuing it in court is still a civil action subject to the ordinary limitations period, so it is not an entitlement that sits open indefinitely.
Dog bite law varies more between states than most people expect — the same attack can be a straightforward claim in one state and a difficult one across a state line.
| State | Rule | Statute | Deadline | Shared fault | What stands out |
|---|---|---|---|---|---|
| Alabama dog bite laws | Mixed statute | Ala. Code § 3-6-1 | 2 years | Contributory (any fault bars) | The statute reaches bites on the owner’s property only, and § 3-6-3 cuts the claim to actual expenses where the owner knew nothing about the dog. |
| Alaska dog bite laws | One-bite / negligence | No statute (AS 09.17.010 caps damages) | 2 years | Pure comparative | Non-economic damages capped at $400,000 — or $1,000,000 where the injury is severe permanent disfigurement. |
| Arizona dog bite laws | Strict liability | A.R.S. § 11-1025 | 1 year (statutory) / 2 years (negligence) | Pure comparative | Shortest deadline in the country for the statutory claim; breed cannot be considered by any legal decision-maker. |
| Arkansas dog bite laws | One-bite rule | No civil statute (Ark. Code § 5-62-125 criminal) | 3 years | Modified (50% bar) | Recovery is barred at exactly 50 percent fault, not 51 — and a minor’s window runs three years past majority. |
| California dog bite laws | Strict liability | Civ. Code § 3342 | 2 years | Pure comparative | Minor's claim tolled until age 18; cities cannot ban dogs by breed. |
| Colorado dog bite laws | Mixed statute | C.R.S. § 13-21-124 | 2 years | Modified (50% bar) | Strict liability reaches economic damages only, and only on serious bodily injury. A posted "Beware of Dog" sign is a complete defense. |
| Connecticut dog bite laws | Strict liability | Conn. Gen. Stat. § 22-357 | 3 years (statutory) / 2 years (negligence) | Modified (51% bar) | Covers any damage a dog does, not just bites. A child under seven is presumed not to have trespassed or teased — the burden shifts to the defendant. |
| Delaware dog bite laws | Strict liability | 16 Del. C. § 3053F | 2 years | Modified (51% bar) | Animal control is run statewide by Delaware Animal Services rather than by each city — the only state on this site with a single centralised agency. |
| District of Columbia dog bite laws | Mixed statute | D.C. Code §§ 8-1808, 8-1812 | 3 years | Pure contributory — 1% bars all recovery | Letting a dog run at large is evidence of negligence, and lack of knowledge is no excuse — but any contributory fault at all still defeats the claim. |
| Florida dog bite laws | Strict liability | Fla. Stat. § 767.04 | 2 years | Modified (51% bar) | A posted "Bad Dog" sign is a complete defense — except against a child under 6. |
| Georgia dog bite laws | Mixed statute | O.C.G.A. § 51-2-7 | 2 years | Modified (50% bar) | A violated local leash ordinance is by itself sufficient proof of vicious propensity. Fault bar sits at 50%, not 51%. |
| Hawaii dog bite laws | Mixed statute | Haw. Rev. Stat. § 663-9 | 2 years | Modified (51% bar) | The statute removes the scienter requirement but not the need to prove unreasonable conduct — except for animals dangerous by species or nature, where liability is absolute. |
| Idaho dog bite laws | One-bite rule | No civil statute; Idaho Code § 25-2805 (at large) | 2 years | Modified (50% bar) | No strict liability statute. Recovery runs on scienter or negligence, and the fault bar sits at 50%, not 51%. |
| Illinois dog bite laws | Strict liability | 510 ILCS 5/16 | 2 years (1 year vs. a local public entity) | Modified (51% bar) | Covers attacks and attempted attacks with no bite, and "owner" includes anyone who keeps, harbors or has custody of the dog. |
| Indiana dog bite laws | Mixed statute | Ind. Code § 15-20-1-3 | 2 years | Modified (51% bar) | Strict liability applies ONLY to people performing a duty imposed by law — mail carriers, meter readers, police. Everyone else gets the one-bite rule. |
| Iowa dog bite laws | Strict liability | Iowa Code § 351.28 | 2 years | Contributory negligence is not a defense | Unusually claimant-friendly: the only statutory defenses are that the victim was committing an unlawful act, or that the dog had rabies. |
| Kansas dog bite laws | One-bite rule | No civil statute — common-law scienter | 2 years | Modified (50% bar) | No dog bite statute, and the fault bar sits at 50%. Local leash ordinances do most of the practical work in establishing negligence. |
| Kentucky dog bite laws | Strict liability | KRS 258.235(4) | 1 year | Pure comparative | The statutory definition of "owner" is broad enough to make a landlord strictly liable — Maupin v. Tankersley (Ky. 2018). Only one year to file. |
| Louisiana dog bite laws | Strict liability | La. Civ. Code art. 2321 | 2 years (1 year before 1 July 2024) | Pure comparative | A civil-law jurisdiction. Prescription doubled from one year to two on 1 July 2024, and the change applies only to injuries arising after that date. |
| Maine dog bite laws | Mixed statute | 7 M.R.S. § 3961 | 6 years | Modified (50% bar) | The longest filing deadline in the country at six years — but strict liability applies only where the dog injured you OFF the owner's premises. |
| Maryland dog bite laws | Strict liability (at large) + presumption | Cts. & Jud. Proc. § 3-1901 | 3 years | Pure contributory (any fault bars) | Breed-neutral since a 2014 legislative reversal of Tracey v. Solesky — but pure contributory negligence stacked on genuine strict liability means any claimant fault, even 1%, can still zero out the claim. |
| Massachusetts dog bite laws | Strict liability (owners and keepers) | MGL c. 140, § 155 | 3 years | Modified (51% bar) | Keeper liability runs against anyone temporarily caring for the dog — boarding kennels, dog walkers, pet sitters — on the same strict liability terms as the owner. Double damages are mandatory (not discretionary) where the owner had prior knowledge. |
| Michigan dog bite laws | Strict liability | MCL 287.351 | 3 years | Modified — bars non-economic damages only | Over 50% fault removes pain and suffering but not medical bills. Provocation is judged objectively, so an accidental act can count. |
| Minnesota dog bite laws | Strict liability | Minn. Stat. § 347.22 | 6 years | Modified (51% bar) | Six-year filing deadline — the longest of any strict liability state on this site. The statute covers any "attack or injury," not only bites, giving full protection to victims knocked down or injured by large dogs without being bitten. |
| Mississippi dog bite laws | One-bite rule | Miss. Code § 15-1-49 (no civil bite statute) | 3 years | Pure comparative | Mississippi is one of very few states with no civil dog bite statute — claims run on common law, requiring proof the owner knew the dog was dangerous before the attack. Mississippi's pure comparative fault rule means even a plaintiff with significant fault recovers a proportional share of damages. |
| Missouri dog bite laws | Strict liability | RSMo § 273.036 | 5 years | Pure comparative | Longest filing window on this list; minor's claim tolled to 21. |
| Montana dog bite laws | Strict liability | Mont. Code § 27-1-715 | 3 years | Modified (51% bar) | Rural insurance market means coverage confirmation is a critical early investigation step — uninsured homeowners rates are higher in Montana than in most urban strict liability states on this site. |
| Nebraska dog bite laws | Strict liability | Neb. Rev. Stat. § 54-601 | 4 years | Modified (50% bar) | Four-year filing deadline — one of the longest of any strict liability state. § 54-601 covers "killing, wounding, injuring, worrying, or chasing" — broader than bite-only statutes. |
| Nevada dog bite laws | Negligence (no statute) | No dog bite statute — Glass v. Eighth Judicial Dist. Ct., 87 Nev. 321 (1971) | 2 years | Modified (51% bar) | The only state here with no dog bite statute at all. Nevada rejected the one-bite rule in 1971 — claims run on ordinary negligence. |
| New Hampshire dog bite laws | Strict liability | RSA 466:19 | 3 years | Modified (51% bar) | Defenses are statutory and narrow — only trespass and deliberate provocation (teasing, tormenting, abusing the dog) are complete defenses. Government entity claims require written notice within 60 days for municipal defendants under RSA 507-B:7. |
| New Jersey dog bite laws | Strict liability | N.J. Stat. § 4:19-16 | 2 years | Modified (51% bar) | One of the oldest strict liability statutes in the country (enacted 1933). Harboring liability extends to landlords and employers who knowingly permit a dangerous dog — both faces of the same claim, not alternatives. |
| New Mexico dog bite laws | One-bite rule | NMSA § 37-1-8 (no civil bite statute) | 3 years | Pure comparative | Government entity notice deadline is only 90 days under the New Mexico Tort Claims Act (NMSA § 41-4-16) — the shortest of any state on this site. Claims run on common law with no civil dog bite statute. |
| New York dog bite laws | Mixed statute | N.Y. Agric. & Mkts. Law § 123 | 3 years | Pure comparative | Strict liability covers medical and veterinary costs only. Flanders v. Goodfellow (Apr 2025) restored ordinary negligence claims after 19 years. |
| North Carolina dog bite laws | Mixed statute | N.C.G.S. §§ 67-4.4, 67-12 | 3 years | Pure contributory — 1% bars all recovery | The harshest fault rule in the country. Any contributory negligence at all, however slight, defeats the entire claim. |
| North Dakota dog bite laws | One-bite rule | NDCC 28-01-16(5) (no civil bite statute) | 6 years | Modified (50% bar) | Six-year filing deadline — the longest personal injury window of any state on this site. Modified 50% bar means a plaintiff at exactly 50% fault recovers nothing — stricter than the 51% bar in neighboring Wyoming and New Hampshire. |
| Ohio dog bite laws | Strict liability | Ohio Rev. Code § 955.28(B) | 2 years | Modified (51% bar) | Liability reaches the owner, keeper AND harborer. Avery's Law (Mar 2026) added a $100,000 insurance mandate for dangerous dogs. |
| Oklahoma dog bite laws | Strict liability | 4 O.S. § 42.1 | 2 years | Modified (50% bar) | Oklahoma's comparative fault bar falls at 50% — a plaintiff found exactly 50% at fault recovers nothing. This is one percentage point more restrictive than Oregon and New Jersey, where 50% plaintiff fault still allows a half-damages recovery. |
| Oregon dog bite laws | Strict liability | ORS 31.360 | 2 years | Modified (51% bar) | Oregon bans breed-specific ordinances statewide under ORS 609.205 — no city or county may restrict or regulate dogs by breed. The liability analysis under ORS 31.360 is fully breed-neutral. |
| Pennsylvania (this page) | Mixed statute | 3 P.S. § 459-502 (Dog Law) | 2 years | Modified (51% bar) | Strict liability covers medical costs only. Pain and suffering requires proving a "severe injury" or the dog's dangerous propensities. |
| Rhode Island dog bite laws | Strict liability | RIGL § 4-13-16 | 3 years | Pure comparative | Pure comparative fault — recovery is never barred by victim fault, regardless of the percentage. A plaintiff found 90% at fault still recovers 10% of their damages. The most plaintiff-favorable comparative fault system in New England. |
| South Carolina dog bite laws | Strict liability | S.C. Code § 47-3-110 | 3 years | Modified (51% bar) | Keeper liability is express in the statute — liability extends to any person having the dog "in their care or keeping," making dog walkers and boarding facilities directly liable on the same strict liability terms as the registered owner. |
| South Dakota dog bite laws | Strict liability | SDCL § 40-34-1 | 3 years | Slight/gross doctrine | Extends strict liability to "keepers and harborers" — not just the registered owner. Uses unique "slight/gross" comparative negligence rather than standard percentage-based fault. Government entity claims require 180-day written notice under SDCL § 3-21-2. |
| Tennessee dog bite laws | Mixed statute | Tenn. Code Ann. § 44-8-413 | 1 year | Modified (50% bar) | The only state with a "residential exclusion" — strict liability drops away if the bite happened on the owner's own residential or farm property. |
| Texas dog bite laws | One-bite rule | No statute — Marshall v. Ranne, 511 S.W.2d 255 (Tex. 1974) | 2 years | Modified (51% bar) | No dog bite statute. Recovery requires proving the owner knew of the dog's dangerous propensities, or ordinary negligent handling. |
| Utah dog bite laws | Strict liability | Utah Code § 18-1-1 | 4 years | Modified (50% bar) | Four-year filing deadline — one of the longest of any strict liability state in the country. Utah's statute also has no express lawful-presence language, making the reach of strict liability potentially broader than states with that textual limitation. |
| Vermont dog bite laws | Strict liability | 20 V.S.A. § 3461 | 3 years | Modified (51% bar) | Statute requires victim to have been "peaceably conducting himself or herself" in a lawful location — courts interpret this narrowly to exclude only deliberate provocateurs, not ordinary people in normal activity. Vermont's rural character means farm policies rather than homeowners insurance are common in agricultural-area cases. |
| Virginia dog bite laws | One-bite rule | No civil statute — common-law one-bite rule | 2 years | Pure contributory (any fault bars) | Two compounding disadvantages for victims: no strict liability statute (must prove owner's prior knowledge) plus pure contributory negligence (any fault bars entirely). Strict liability only available after a prior "dangerous dog" designation under § 3.2-6553. |
| Washington dog bite laws | Strict liability | RCW 16.08.040 | 3 years | Pure comparative | Broad strict liability, but provocation is a COMPLETE defense — and a fenced or posted property removes the implied consent that makes you lawfully present. |
| West Virginia dog bite laws | Strict liability | W. Va. Code § 19-20-13 | 2 years | Modified (51% bar) | Harboring theory expressly extends strict liability to landlords who knowingly allowed a dangerous dog on their rental property — a second defendant category not available in most strict liability states. |
| Wisconsin dog bite laws | Strict liability | Wis. Stat. § 174.02 | 3 years | Modified (51% bar) | Double damages are mandatory by statute — not discretionary — whenever the owner was notified or knew the dog had previously injured someone. The entire damages award doubles automatically once prior knowledge is established. |
| Wyoming dog bite laws | One-bite rule | Wyo. Stat. § 1-3-105 (no civil bite statute) | 4 years | Modified (51% bar) | Four-year filing deadline — the longest of any one-bite rule state on this site. Modified 51% bar means a plaintiff at exactly 50% fault still recovers half their damages, unlike neighboring one-bite states. |
Pennsylvania dog bite questions, answered
The questions Pennsylvania readers ask most often. General information, not legal advice.
Is Pennsylvania a strict liability state for dog bites?
Only for medical costs, which is why this site classifies it as a mixed statute. Under 3 P.S. § 459-502 the owner or keeper must pay all medical costs resulting from an attack regardless of fault or the dog's history. Pain and suffering, scarring and lost wages require something more: either a "severe injury" or proof the owner knew of the dog's dangerous propensities.
What counts as a "severe injury" in Pennsylvania?
The Dog Law defines it as any physical injury that results in broken bones or disfiguring lacerations requiring multiple sutures or cosmetic surgery. That definition is doing real work in a Pennsylvania claim — it is often the line between recovering medical costs alone and recovering full damages.
Does the owner have to pay my medical bills even if they were not negligent?
Yes. That obligation is the core of 3 P.S. § 459-502 and it applies in every bite case, without any need to prove negligence or show the dog had bitten before. It is a floor rather than a ceiling — meeting it does not resolve a claim for pain and suffering.
Do I still need to prove the dog had bitten before?
Not necessarily. A 2024 amendment removed the prior-propensity requirement from Pennsylvania's dangerous dog provisions, so a first attack causing severe injury can support a dangerous dog determination. Evidence the owner knew the dog was dangerous still helps, but it is no longer the only route.
How long do I have to file in Pennsylvania?
Two years from the date of the bite under 42 Pa.C.S. § 5524. For a minor, § 5533(b) tolls the period until they turn 18. If a Commonwealth or local agency is involved, written notice is required within six months under § 5522, which is a much shorter and easily missed deadline.
Can I recover if I was partly at fault?
For the negligence part of the claim, yes, up to a point — 42 Pa.C.S. § 7102 reduces your damages by your share of fault and bars recovery once your fault exceeds the defendant's. The Dog Law obligation to pay medical costs operates on a separate footing from that comparative fault analysis.
Can a Pennsylvania city ban pit bulls?
No. 3 P.S. § 459-507-A preempts breed-specific regulation statewide, so no Pennsylvania municipality may regulate dogs by breed. Breed is not part of the liability analysis in any event.
Key Takeaways for Pennsylvania Dog Bite Victims
Pennsylvania follows the Mixed Statute standard — that determines whether you need to prove the owner's prior knowledge or can hold them liable automatically. Understanding which standard applies is the first step in knowing whether you have a viable claim.
Your filing deadline is fixed by state law. Missing it permanently closes your case, no matter how strong the evidence is. Start the clock from the date of the bite.
Document everything from day one — photos of the injury, medical records, the dog owner's name, and any witness contact details. That documentation is the single most controllable factor in how much you ultimately recover.
