Dog bites can cause devastating physical, emotional, and financial harm for victims and their families. But are certain dog breeds involved in severe attacks more often than others?
According to national dog bite statistics, some breeds are more commonly associated with severe or fatal attacks than others. However, a dog’s behavior is influenced by multiple factors, including training, environment, owner negligence, socialization, and prior aggression history.
When dog attacks happen, victims are often left dealing with serious injuries, medical expenses, lost income, permanent scarring, and emotional trauma. Understanding dog bite statistics and breed-related injury trends can help victims better understand liability, risk factors, and their legal rights after an attack.
At Mattiacci Law LLC, our Pennsylvania dog bite lawyers help injury victims pursue compensation after serious dog attacks. Below, we break down the latest dog bite statistics by breed, common injury risks, legal considerations, and what victims should know after an attack.
Which Dog Breeds Are Most Commonly Involved in Serious Dog Attacks?
Studies analyzing severe and fatal dog attacks have found that certain large and powerful breeds appear more frequently in reported incidents involving catastrophic injuries or fatalities.
Some breeds commonly referenced in dog bite injury studies include:
- Pit Bull-Type Dogs
- Rottweilers
- German Shepherds
- American Bulldogs
- Huskies
- Mastiffs
- Doberman Pinschers
- Cane Corsos
- Akitas
- Belgian Malinois
It is important to understand that breed alone does not determine whether a dog is dangerous. Many attacks involve additional contributing factors such as:
- Lack of proper training
- Neglect or abuse
- Failure to restrain the dog
- Encouraging aggressive behavior
- Poor socialization
- Prior bite history
- Unneutered male dogs
- Owner negligence
The American Veterinary Medical Association (AVMA) has repeatedly stated that no single factor can accurately predict whether a dog will become aggressive.
Dog Bite Fatality Statistics by Breed
Research reviewing fatal dog attacks in the United States has found that pit bull-type dogs and Rottweilers are involved in a significant percentage of reported fatal incidents.
However, experts caution that breed identification can sometimes be inaccurate in media reports and public records. Additionally, fatal dog attacks are statistically rare compared to the total dog population in the United States.
Estimated Dog Bite Fatality Trends
| Breed Type | Frequently Reported in Fatal Attack Studies | Common Injury Severity |
|---|---|---|
| Pit Bull-Type Dogs | High | Severe crushing injuries |
| Rottweilers | High | Severe bite force injuries |
| German Shepherds | Moderate | Puncture and tearing injuries |
| Huskies | Moderate | Facial and upper-body injuries |
| Mastiffs | Moderate | Crushing trauma |
| Mixed Breeds | Variable | Variable |
Fatal attack statistics vary by study methodology, reporting standards, and breed identification accuracy.
What Dog Breeds Cause the Most Insurance Claims?
Insurance companies often analyze dog bite claim data based on injury severity, settlement payouts, and frequency of reported attacks rather than breed alone.
According to the Insurance Information Institute:
- Dog bite claims account for hundreds of millions of dollars in homeowner insurance payouts each year
- Severe facial injuries and permanent scarring often result in the largest settlements
- Children are among the highest-risk victims
- Large breeds with strong bite force tend to produce more catastrophic injuries
Some insurance companies restrict or exclude coverage for certain breeds viewed as higher risk. These breed restrictions vary by insurer and state.
Are Certain Dog Breeds More Aggressive Than Others?
Aggression in dogs is influenced by genetics, training, environment, socialization, health conditions, and owner behavior—not just breed.
Veterinary experts warn against assuming that all dogs of a particular breed are inherently dangerous. Many dogs commonly labeled “aggressive” never bite anyone during their lifetime.
Factors more strongly associated with aggression include:
- Poor owner supervision
- Lack of obedience training
- Prior abuse or neglect
- Territorial behavior
- Fear-based aggression
- Chaining or isolation
- Improper breeding practices
Even smaller dogs can cause serious injuries under certain circumstances.
What Dog Breeds Have the Strongest Bite Force?
Certain large breeds are capable of exerting substantial bite force, which can increase the severity of injuries during an attack.
Estimated Bite Force Comparison
| Breed | Estimated Bite Force (PSI) |
|---|---|
| Cane Corso | 650–700 PSI |
| Mastiff | 550+ PSI |
| Rottweiler | 320–350 PSI |
| German Shepherd | 230–250 PSI |
| American Bulldog | 300+ PSI |
| Pit Bull-Type Dogs | Estimated 235–330 PSI |
PSI estimates vary across studies and testing methods.
A stronger bite force may increase the likelihood of:
- Bone fractures
- Nerve damage
- Facial trauma
- Tissue loss
- Permanent scarring
- Reconstructive surgery
Which Victims Face the Highest Risk of Severe Dog Bite Injuries?
Children are statistically among the most vulnerable dog bite victims due to their height, size, and inability to defend themselves during an attack.
Children are more likely to suffer:
- Facial injuries
- Eye injuries
- Neck trauma
- Permanent disfigurement
- Emotional trauma
Older adults may also face increased complications due to:
- Falls during attacks
- Infection risks
- Reduced mobility
- Delayed healing
Common Injuries in Serious Dog Attack Cases
Dog attacks can cause far more than simple puncture wounds.
Severe Dog Bite Injuries May Include:
- Deep puncture wounds
- Torn ligaments and tendons
- Nerve damage
- Crushed bones
- Facial disfigurement
- Scarring
- Eye injuries
- Infections
- PTSD and emotional trauma
- Wrongful death
Some victims require:
- Skin grafts
- Multiple surgeries
- Long-term rehabilitation
- Psychological counseling
Does Pennsylvania Have Strict Liability for Dog Bites?
Pennsylvania law allows dog bite victims to pursue compensation when an owner fails to properly control or restrain a dangerous dog.
Pennsylvania dog bite liability may depend on:
- Prior aggressive behavior
- Negligence by the owner
- Local leash law violations
- Whether the victim was lawfully present
- The severity of injuries
Victims may be entitled to compensation for:
- Medical bills
- Lost wages
- Pain and suffering
- Permanent scarring
- Emotional distress
- Future medical treatment
What Should You Do After a Dog Attack?
Taking immediate action after a dog bite can help protect both your health and your legal claim.

- Seek immediate medical attention
- Report the attack to local authorities
- Identify the dog owner
- Photograph injuries and the scene
