But before these statistics cause you to condemn a breed for being vicious or judge an owner for breeding a beast, ask yourself a simple question, “Why do dogs bite?”

According to a study by the Center for Disease Control (CDC), approximately 4.5 million dog bites occur in the United States each year, and 800,000 of those bites result in medical attention. The U.S. population was approximately 328.2 million people in 2019. That means a dog bites 1 in 73 people.

National dog bite statistics

A dog will not bite you for no reason. Several triggers can set off this behavior. That is, dogs will often bite if they are in danger, frightened or stressed.

What causes a dog to bite, the facts reveal, is usually the need to protect their puppies, their owners or themselves. It is their way of protecting their loved ones.

There were more than 90 million dogs in the U.S. in 2019/2020. (The Washington Post, HSUS, AVMA)

Recent dog attack data from 2020 shows that these dogs were divided among 84.9 million households with pets. This means that 50% of all households in the U.S. had a dog as a pet. This number suggests a higher incidence of bites.

The 2020 AVMA dog bite statistics show that animals bite primarily because of their personal history and behavior. Dogs that were abused or mistreated in animal shelters may be traumatized, causing them to attack.

Dogs bite about 4.5 million people each year, U.S. dog attack statistics reveal. (Canine Journal)

The Center for Disease Control (CDC) regularly studies dog bites and attacks in the United States. They reveal that only 800,000 of all dog bites need medical attention.

Since the mid-1990s, the CDC has been studying various dog breeds, their temperament and situations that prompt them to attack.

CDC dog bite statistics by breed revealed that pit bulls were involved in the most accidents and injuries. Pit bulls are arguably one of the most aggressive dogs in existence. They are responsible for nearly 300 deaths.

However, it is important to note that this is because they are a popular breed specifically trained by owners to be aggressive rather than the breed itself having an aggressive temperament.

Pit bull bite statistics show that the breed was responsible for 26 deaths in 2018.


As we mentioned, there were 36 dog-related deaths in the U.S. in 2018. Pitbulls are responsible for 72% of them, even though they represent only 7% of the dog population in the U.S., As Pit Bull attacks vs. reveal statistics for other breeds.

However, pit bulls are not the type of dogs that will bite just anyone for no reason. Regardless of dog breeds, statistics reveal that it is the ruthless owners who are responsible for their dogs’ aggression, as many of them have criminal records. Among all the dogs, pit bulls have an 86.7% pass rate for temperament.

(dog wow)

People see pit bulls as the most vicious dogs in the world because some owners use them for fighting. However, their temperament approval rating is higher than that of the Chihuahua, Border Collie or Beagle.

They don’t even have the strongest dog bite. As dog bite strength statistics by breed reveal, pit bulls have one of the weakest bite strengths of all breeds: only 235 pounds per square inch (PSI).

Dog breed could not be identified as one of the factors in 80% of dog bite cases, as shown by dog bite statistics.

(National Canine Research Council)

In fact, breeds are mainly used for media coverage, but not necessarily as a confirmed fact. In only slightly more than 18% of cases was it possible to make a valid determination whether the dog was of a particular breed.
15. Kangal is the breed with the strongest dog bite force of 743 PSI.

(Within the dog world)

Bandog Dog has the second strongest bite force (730 PSI), followed by the Cane Corso (700 PSI) and the Dogue de Bordeaux (556 PSI).

How to protect yourself against the risk of dog bites

Dog liability insurance is a special policy you can get to insure yourself in case you have what an owner or other important person in your life might consider a “dangerous breed of dog.”

If you have one of these dogs, you probably know this, as some people are probably a little afraid of your puppy. It’s unlikely to be necessary, but it’s better to be safe than sorry in case a situation arises where your dog bites someone.

Why? Because with liability insurance you would simply file a claim and cover the cost of the situation. In many cases, we have heard of dog lives being saved because of the ability to cover these types of incidents by proactively seeking insurance rather than reacting after a bad situation occurs. Better safe than sorry, right?

According to the Insurance Information Institute, one-third of all homeowners insurance liability claims (in dollars) result from dog bites or dog-related injuries, and the average cost is more than $37,000.

Decrease your chances of a dog bite attack.

While we’re not absolving the canine completely of their own responsibility in a dog bite situation, there are always two sides to the story, even a bad one. When it comes to your side, there are more than two things you can do to lessen your chances of an attack.

How to prevent a dog bite

Just like people, there are always good pets that snap. Even though the dog never showed aggressive attitudes, even though you didn’t provoke it to attack, there are still those unexplainable cases that no one can explain or rationalize. However, most of the time, this is not the case.

dog breeds bite the most

That’s why, when dealing with a dog, you should remain confident, but with cautious body language. Here are some things you can do to make sure your attitude doesn’t trigger an attack.

Don’t approach an unfamiliar animal

  • Don’t run away from a dog, panic or make loud noises.
  • If an unfamiliar dog approaches you, remain motionless. Do not run or scream. Avoid direct eye contact.
  • Do not disturb a dog while it is eating, sleeping or caring for puppies.
  • Allow a dog to sniff and sniff you before attempting to pet it. Then scratch the animal under the chin, not on the head.
  • Report stray dogs or dogs exhibiting strange behavior to local animal control.
  • If a dog knocks you down, roll into a ball and remain motionless. Be sure to cover your ears and neck with your hands and stay calm and avoid eye contact
  • Do not encourage your dog to play aggressively.


Things to consider before getting a dog

There are some key things to consider before bringing a new dog into your home, especially if you already have other animals or children. Here are some factors that, if considered, can help decrease the chances of an unwarranted attack before an animal walks through your front door.

  • Dogs with a history of aggression are not appropriate for a home with children. Period
  • Before choosing a dog, do your research and consult with a professional (a trusted veterinarian or dog trainer would be an excellent resource person) to find the best breed for your needs.
  • Proper socialization and training for your dog while it’s still a puppy is key.
  • Spend time with your prospective pet before adopting to determine aggressive tendencies.
  • Spay or neuter your pet to reduce aggressive tendencies before taking him home.

Be aware of the “breeds”, but don’t be afraid

Pit Bull (title: facts and mischaracterizations) You’ve probably heard of the Pit Bull, considered the type most responsible for dog bites. But you can dismantle much of your fear of them with our Pit Bull Facts article.

Unfortunately, claims against pit bulls account for the majority of fatal attacks reported in the United States (again, many of these are misreported due to a lack of understanding of breeds and types of dogs).

While there is no denying that one must be more vigilant with a large dog than, say, a Beagle, there is also no denying that an animal is partly a product of its environment.

Remember that any dog can bite, no matter how well trained. Many popular family dogs have caused fatalities, including Labradors and German Shepherds. Therefore, it is always a good idea to be a responsible dog owner and make sure pets are supervised at all times by others.

Finally, if you have a dog that is prone to biting, consider a training collar or online training courses to help change their bad behavior.

What happens to a dog if it bites a human?

In some cases, it is possible to euthanize a dog that has bitten someone. But such cases are sporadic. Generally, only dogs with a history of aggression and biting are euthanized. Although it is important to note that with proper training and attention, aggression can be reversed.

However, each city, county, country and state may have its own rules when it comes to handling biting dogs.

Although this breed has a very bad reputation, it is statistically calmer than the Chihuahua, as it has a 87.6% temperament pass rate.

How do you handle a dog that bites?

As mentioned, dogs bite for a reason. They may bite to defend themselves, their territory, a member of their pack or their puppies. Scared, injured, sick, teased and abused dogs may also bite.

There are several solutions to this problem, and they include training and socialization, that is, letting the dog interact with people, children and other dogs. Taking care of the dog’s health and regular vaccinations can also help.

Is Aggressive dogs play considered fighting?

A post shared by MyDogBites (

Dog play may seem very aggressive to humans, but there are ways to differentiate between playing and fighting.

If the dog is acting silly, has an open-mouthed grin, bows, growls, voluntarily falls down and comes back for more, he is just playing.

However, as dog bite statistics reveal, if the dog’s body is stiff, hairs are raised, and it has a closed mouth and curled lip, the dog is ready for a fight.

In addition, low growls, quick and efficient movements and flat ears are also signs that a fight could be coming.

Recognizing these signs is crucial to stopping a fight before it happens. However, if your dog fights, don’t try to separate them by grabbing them by the neck, or you could get bitten. Instead, try to distract the dogs with a loud noise.

Can an aggressive dog be cured?

Aggression in dogs can be cured. But you will need a lot of patience, time, consistency and probably the help of a professional who will determine the cause of the behavior and make a plan to manage it.

In addition, your veterinarian may run some tests to see if there is a medical problem. The important thing is to avoid punishment, as it can be counterproductive and fill your puppy with love.



Hopefully this list of dog bite statistics has demonstrated to you that dog bites are not that common, and the reasons that can lead to a dog attack make this picture much less frightening.

In fact, there are some breeds that are more aggressive than others, but it’s not the dog that bites, it’s its history and behavior. You should keep in mind that while a dog may be aggressive, that is no reason to be afraid of an entire breed.
