The Most Dangerous Dog Breeds in America

Certain Dog breeds in America are frequently involved in severe attacks, often due to their size, strength, and temperament. As an attorney with over 15 years of experience representing victims of dog attacks, I’ve seen firsthand the devastating impact these incidents can have. Understanding which breeds are statistically more dangerous is crucial for those affected by dog bites to take appropriate legal steps.

 

What Are the Characteristics of Dangerous Dog Breeds?

Dangerous dog breeds are often defined by traits such as strong physical strength, powerful jaws, high prey drive, and territorial tendencies. Without proper training or socialization, these characteristics can increase the likelihood of aggressive behavior. Responsible ownership and early socialization are key to managing these breeds safely and reducing potential risks.

Pit Bulls Lead Fatal Attack Statistics

Pit Bulls are responsible for 66% of fatal dog attacks between 2005 and 2019, with around 284 deaths during this period. Their strong build and tenacity make them particularly dangerous in attack scenarios. Despite efforts to curb attacks through breed-specific legislation (BSL), Pit Bulls remain the most dangerous breed in the U.S.

Rottweilers Pose Serious Risks

Rottweilers, responsible for 45 fatal attacks during the same period, are the second most dangerous breed. Known for their protective nature and strength, Rottweilers have a bite force of 328 PSI, making them a formidable breed when not properly trained or restrained.

German Shepherds Can Be Aggressive

German Shepherds rank third, with 20 fatal attacks between 2005 and 2019. While commonly used as police dogs due to their intelligence and loyalty, they can become aggressive in stressful situations, especially when protecting their owners.

Wolf Hybrids Are Unpredictable

Wolf Hybrids are a mix between domestic dogs and wild wolves, making them difficult to train and often unpredictable. Their wild instincts contribute to their involvement in several severe attacks.

Chow Chows Are Territorial

Though smaller in size, Chow Chows have a bite force of 220 PSI and are known for their territorial and aggressive behavior. This breed has been involved in multiple fatal and serious non-fatal attacks.

 

 

The most dangerous dog breeds in America can vary in temperament, strength, and behavior, but they share one key trait: frequent involvement in severe attacks. Understanding the risks associated with these breeds can help owners and the public take necessary precautions, as well as help victims of dog bites better understand the circumstances that led to their injuries.

Recent studies and reports indicate that Pit Bulls are most often linked to fatal attacks, accounting for around 66% of all fatal dog attacks from 2005 to 2019 (approximately 284 deaths). Rottweilers, meanwhile, were connected to 45 fatal attacks during the same period. Other breeds, including Mixed Breeds, Wolf Hybrids, and American Bulldogs, also contribute significantly to fatal incidents.

Several factors drive this higher rate of severe incidents. Physically, these breeds possess notable strength and bite force, ranging from around 328 PSI in Rottweilers to over 550 PSI in Mastiffs. Equally important, however, are training, socialization, and overall care. Breeds that are territorial or protective may be more likely to respond aggressively when they perceive a threat to themselves or their family.

Despite the emphasis on physical traits and statistics, critics caution that breed-specific lists can be misleading if they fail to account for factors such as the total population of each breed, individual dog behavior, and environmental influences. Some experts argue that focusing solely on breed oversimplifies the complex issue of dog aggression. A dog’s upbringing, socialization, and how it’s managed play crucial roles in its behavior, regardless of its breed.

It’s also vital to remember that not all dangerous dog incidents result in fatalities. Doberman Pinschers and Mastiffs, for example, can cause severe injuries because of their strength and bite force. Children are particularly vulnerable: around 50% of child victims are bitten on the head and neck, highlighting the need for swift legal action and effective prevention measures.

Below is a comparison table summarizing the most dangerous breeds based on reported fatal attacks, bite force, and other key traits contributing to their classification as high-risk.

 

Breed	Fatal Attacks (2005-2019)	Bite Force (PSI)	Traits
Pit Bull	284	235-250 PSI	Strong, often involved in fatal attacks
Rottweiler	45	328 PSI	Muscular, protective, high-risk when poorly trained
German Shepherd	20	238-240 PSI	Intelligent, protective instincts, used as police dogs
Wolf Hybrid	14	Varies	Wild instincts, difficult to train
Chow Chow	12	220 PSI	Territorial, smaller but aggressive

 

Top 20 Most Dangerous Dog Breeds in America

Identifying the most dangerous dog breeds requires analyzing reports from reputable organizations like the American Veterinary Medical Association and the Centers for Disease Control and Prevention. Drawing from these sources, here’s a list of the top 20 breeds often highlighted in studies on dog-related incidents:

1. Pit Bull Terrier
2. Rottweiler
3. German Shepherd
4. American Bulldog
5. Bullmastiff

Each of these breeds is known for their strength and, in some cases, protective instincts. However, they also demand responsible ownership and training.

6. Siberian Husky
7. Doberman Pinscher
8. Alaskan Malamute
9. Chow Chow
10. Great Dane

These breeds are often noted for their size and power, contributing to their potential risk factor.

11. Saint Bernard
12. Akita
13. Boxer
14. Presa Canario
15. Cane Corso

Their inclusion on this list underlines the importance of understanding breed-specific behaviors.

16. Dogo Argentino
17. Tosa Inu
18. Fila Brasileiro
19. Wolfdog Hybrid
20. Mastiff

When considering these breeds, it’s crucial to remember that environmental factors and training play significant roles in a dog’s behavior. Proper socialization and care can mitigate risks associated with any breed.

Criticisms of Ranking Methodologies for Dangerous Dog Breeds

When it comes to the methodology used to rank dangerous dog breeds, several criticisms frequently emerge:

1. Population Bias: One of the primary critiques is that these lists often fail to consider the total population of each breed. As a result, breeds that are more common may seem disproportionately dangerous simply because their larger numbers lead to a higher incidence of reported attacks.

2. Oversimplification of Aggression Factors: Many experts argue that focusing solely on specific breeds oversimplifies the complex issue of dog aggression. They assert that aggression can be more accurately attributed to individual dog behavior, the quality of training, and the environmental context in which the dog is raised.

3. Legal Implications: From a legal perspective, particularly for victims seeking compensation after dog attacks, these lists can be misleading. The emphasis on breed rather than the specifics of each incident might obscure the nuanced circumstances that contributed to the aggression.

In essence, these criticisms highlight the need for a more nuanced and comprehensive approach to understanding dog aggression, considering factors beyond just breed.

What Are the Legal Responsibilities of Dog Owners?

When a dog attacks, victims often face severe physical and emotional trauma. States like Pennsylvania and New Jersey impose strict liability on dog owners, meaning that owners can be held responsible for their dog’s actions, regardless of whether the dog has shown previous signs of aggression. This makes it easier for victims to seek compensation.

Strict Liability in Dog Bite Cases
Under strict liability laws in Pennsylvania and New Jersey, dog owners are liable for injuries caused by their dogs, even if the dog had no history of biting or aggression. Victims do not need to prove negligence—only that the bite occurred and caused harm.

Is Pennsylvania a One-Bite Rule State, and What Does Its Dog Bite Liability Law Entail?

Pennsylvania does not adhere to a traditional “one-bite rule.” Instead, under Pennsylvania’s Dog Law, dog owners are strictly liable for any medical expenses arising from a dog bite, regardless of the animal’s prior conduct. However, if the victim seeks non-economic damages (such as pain and suffering), they generally must prove the owner’s negligence or demonstrate that the dog had a history of aggressive behavior.

Understanding Pennsylvania’s Dog Bite Law

In Pennsylvania, the Dog Law (3 P.S. § 459-101, et seq.) imposes certain liabilities on dog owners when their pets cause injury to others. Notably, Pennsylvania follows a form of strict liability for medical expenses: if a dog bites someone who is lawfully on public or private property, the owner is responsible for the victim’s reasonable medical costs, regardless of the dog’s prior behavior.

Non-Economic Damages

For non-economic damages—such as pain and suffering—the victim generally must prove one of the following:

1. Negligence by the Dog Owner
   The owner failed to take reasonable steps to prevent the bite, such as allowing the dog to run loose or not properly restraining it.

2. Knowledge of the Dog’s Aggressive Propensity
   Evidence that the dog had a known history of aggression (e.g., prior attacks or documented complaints).

Exceptions to the Rule

In Pennsylvania, while dog owners are generally held responsible for a bite victim’s medical expenses, there are notable exceptions regarding liability for non-economic damages. For example, owners may not be liable for pain and suffering if the person bitten was trespassing on private property or deliberately provoking the dog.

Additionally, if the dog was acting in its capacity as a law enforcement animal during the incident, the owner may also be exempt from certain liabilities. These exceptions acknowledge situations where the dog’s actions might be justified under the circumstances, thereby reducing or eliminating the owner’s legal responsibility for non-economic damages.

Pennsylvania law also recognizes certain situations in which liability may not apply, including:

• Trespassing: If the person bitten was unlawfully on the property.
• Provocation: If the victim teased, tormented, or otherwise provoked the dog into attacking.
• Law Enforcement Animals: When the dog was performing official duties (e.g., K-9 police dogs) at the time of the incident.

By balancing strict liability for medical costs with the need to prove negligence or aggressive history for other damages, Pennsylvania’s Dog Law ensures that victims can seek compensation for legitimate harm while acknowledging scenarios where liability may not be appropriate.

Statute of Limitations for Dog Bite Claims

Victims have a limited time to file a claim after a dog bite. In Pennsylvania and New Jersey, the statute of limitations for filing a dog bite claim is two years. Failing to file within this timeframe can result in the loss of your right to seek compensation.

Types of Compensation

Dog bite victims may be entitled to compensation for:

• Medical costs: Including emergency care, surgeries, and rehabilitation.
• Lost wages: Due to time off work for recovery.
• Pain and suffering: Physical and emotional trauma caused by the attack.
• Permanent disfigurement: Scarring or long-term injuries resulting from the bite.

 

Settling Dog Bite Cases Out of Court: What to Expect

When dealing with a dog bite incident, many individuals wonder about the likelihood and process of reaching a settlement without going to trial. The good news is that most dog bite cases—around 90%—are resolved through mediation rather than courtroom battles.

The Mediation Process

1. Initial Assessment: The first step involves consulting with a legal professional who will evaluate the details of your case. This includes examining medical reports, witness statements, and any relevant evidence.

2. Contacting the Insurance Company: Typically, the perpetrator’s insurance company is notified. Negotiations then commence to determine a fair compensation. Having legal representation can ensure that this process is handled efficiently and to your best advantage.

3. Engaging in Mediation: Mediation is a structured negotiation facilitated by a neutral third party. It offers a platform for both parties to discuss their perspectives and reach an amicable agreement.

4. Reaching a Settlement: If an agreement is reached during mediation, the terms are documented, and both parties sign off. This means that the case is resolved without the need for further legal action.

Benefits of Settling Out of Court

• Cost-Effective: Avoiding a lengthy trial can save both time and money.
• Confidentiality: Settlements are usually private, whereas court cases are public record.
• Control Over Outcome: Parties have more influence over the final settlement terms, compared to a court-mandated decision.

By understanding this process, you can make informed decisions and potentially resolve your dog bite case efficiently and favorably.

What Legal Actions Can Be Pursued After a Dog Bite Injury?

After experiencing a dog bite injury, several legal actions may be available to you. Here’s a guide on the steps you can take to protect your rights and seek compensation:

Immediate Steps to Take

1. Obtain Medical Care
   First and foremost, seek medical attention to treat your injuries and prevent infection. This visit will also generate medical records documenting your injury, crucial for any future legal claims.

2. Report the Bite
   File a report with your local animal control or law enforcement. This report can provide evidence if you decide to pursue a legal claim and may prompt a formal investigation.

3. Identify Involved Parties
   Gather information about the dog and its owner. Knowing the owner is critical for pursuing any legal claims. If the dog is unowned or stray, authorities may assist in identifying the responsible parties.

4. Gather Evidence
   Document the scene and your injuries with photos. Collect witness statements and any communications with the dog owner to bolster your case.

Legal Options Available

1. Consult a Legal Professional
   Contact an attorney specializing in dog bite cases. They can offer valuable advice on your rights and guide you through potential legal proceedings. They also evaluate your case to determine the best course of action.

2. Explore Legal Claims in Pennsylvania

   1. Strict Liability
      Under Pennsylvania’s Dog Law, dog owners can be held strictly liable for medical expenses if their dog bites someone, regardless of the animal’s past behavior. This means victims do not need to prove negligence to recover these costs.

   2. Negligence
      If the owner failed to exercise reasonable care—such as not restraining a known dangerous dog—they may be held financially responsible for additional damages, including pain and suffering.

   3. One-Bite Rule
      Pennsylvania does not follow a traditional one-bite rule. However, evidence of the dog’s prior bites or aggressive behavior can still impact claims by demonstrating the owner’s knowledge of potential danger and strengthening a negligence claim.

3. Personal Injury Lawsuit
   If settlements are insufficient or unavailable, you may choose to file a lawsuit against the dog owner. Successful suits can result in compensation for hospital bills, lost wages, and pain and suffering.

4. Negotiate Settlements
   Many dog bite cases are resolved through settlements rather than going to trial. Negotiating with the dog owner’s insurance company can often lead to a fair compensation agreement.

Understand Timelines

Act quickly, as state statutes of limitations restrict how long you have to file a lawsuit. Promptly pursuing legal action ensures that your case remains viable.

By following these steps and understanding your legal options, you can better navigate the aftermath of a dog bite incident and protect your interests.

Which Factors Influence Dog Aggression?

Although certain breeds are more often involved in attacks, several factors can contribute to a dog’s aggressive behavior.

Lack of Training and Socialization
Dogs that are not properly trained or socialized are more likely to become aggressive. Socialization from an early age can reduce aggression by exposing dogs to different environments, people, and animals.

Owner Negligence
Owners who fail to properly supervise, train, or restrain their dogs may be held responsible for attacks. Negligent behavior, such as failing to control an aggressive dog, increases the risk of incidents.

Stressful or Abusive Environments
Dogs raised in environments where they are mistreated or stressed are more likely to display aggression. Dogs living in overcrowded or harsh conditions often exhibit unpredictable behaviors.

 

What Are the Most Important Steps to Take After a Dog Attack?

Taking immediate action after a dog attack is crucial for your safety and the success of any legal claims you may pursue.

Seek Medical Attention
Even if the bite appears minor, seek medical treatment to prevent infections and ensure that any injuries are properly documented. Medical records are essential when filing a claim.

Report the Incident
Notify local authorities or animal control to create an official record of the attack. This report can serve as evidence if you decide to take legal action.

Document the Attack
Take photos of your injuries, the location of the incident, and any other relevant details. Gather witness statements if possible to support your claim.

Are Children at Greater Risk for Dog Attacks?

Children are disproportionately affected by dog bites due to their size and proximity to dogs. According to recent statistics, nearly 50% of dog bite victims are children. These attacks often result in severe injuries to the head, face, and neck, leading to long-term trauma. If your child has been bitten by a dog, Mattiacci Law can help you pursue compensation for medical treatment and emotional distress.

 

 

What Are the Best Ways to Prevent Dog Attacks?

While it’s impossible to predict every dog’s behavior, there are ways to reduce the risk of an attack:

• Avoid approaching unfamiliar dogs.
• Teach children how to safely interact with dogs.
• Never run from an aggressive dog, as this can trigger their instinct to chase.
• Keep a safe distance from dogs that show signs of aggression.

 

What is Breed-Specific Legislation?

Breed-specific legislation (BSL) is enacted in some areas to regulate ownership of certain dangerous dog breeds, such as Pit Bulls and Rottweilers. These laws often aim to reduce the number of severe dog attacks, but they can be controversial. While some argue that these laws unfairly target specific breeds, others believe they are necessary to protect public safety. In states like Pennsylvania and New Jersey, where BSL is less common, strict liability laws offer protection for dog bite victims regardless of the breed involved.
