The best friend a person can have is a dog. This is not the first time we hear this saying about our loving dogs.

Boston Terrier Bite Force

Whether for practical reasons or emotional reasons a dog is often seen as an assistant to its owner.

Dogs are trained to perform some tasks as a means to help their owners and make their lives easier.

Dogs are known for being friendly and adorable.

People love them because of that. If you show your dog some tenderness and love you can expect the same in return.

Nevertheless as with humans dogs do not always have a good mood. Its possible for dogs to be mean and hurt people at times especially when provoked.

Approximately 4.5 million people in the United States are bitten by dogs each year according to the US Centers for Disease Control (CDC). Half of these bites occur in children. There are approximately 740 dog bites for every 100 000 people in the UK each year.

What do I mean by dog bite force and how is it measured?

Rarely do we discuss the force of dog bites when we discuss dog bites. What does a dog bite force mean? A dog bite force measures the strength of your dogs bite. One of the factors to consider for a dogs strength is its bite force. The force or pressure of a dog bite varies depending on the substance being bit the mood of your dog or the breed of your dog.

Due to all the factors that you need to consider when measuring bite force it can be difficult to measure the force of a dogs bite. 

It isnot ethical to provoke a dog just for a scientific test since dogs normally do not bite hard unless they are provoked.

 The bite force is measured in pounds per square inch (PSI) according to a scientific method.

One square inch of space is subjected to this force.  

A well-known measure of PSI is the pressure index.

This unit is what I use to ensure that my tires are inflated to the proper pressure as a car driver.

The measurement of a dogs bite force is a little more challenging than the measurement of tire pressure as you can imagine.

A dogs behavior is more inconsistent than a tires.

Their bite force ranges from 230 psi to 250 psi across most dog breeds. 

The bite from a Boston Terrier is another matter.

Do they exert a lot of force?

The Boston Terrier is generally a playful dog. It is important to know the common traits of this breed if you own one or plan to own one. Their owners appreciate their joyful personalities and desire to please them. Although they can sometimes be stubborn they are playful and generally good.

They tend to bite anything because Boston terriers are playful and mouthy. Some may view this as aggressive behavior but it could also mean that they are interacting with you. Boston terriers must be trained before they develop the habit of biting everything including their owners. Start training them as young as possible.

People are not usually bitten by Boston Terriers unless provoked. In the United States pitbull terriers are still responsible for the majority of fatal dog attacks. 

How many people do Boston Terriers kill every year?

There is no consensus that Boston Terriers are among those breeds that bite fatally. 

How to train your Boston Terrier not to bite?

In the future you can benefit from teaching your Boston terrier about biting and nipping. Puppy training is much easier than training an older dog which is why you need to train them young.

Training your Boston terrier can be done in a number of ways.

Define Task

Decide what behaviors are acceptable for your Boston terrier. In order to prevent biting give them all the toys they are allowed to chew and anything else is forbidden. As a dog owner it is crucial that you are patient and consistent when training your Boston Terrier.

Get started as early as possible

A dog should always be trained as soon as possible as mentioned before. Boston terriers will always play which is why it is best to inform them about the boundaries.

Choose a different method to train them

To train your dog there are many methods available. Which method you choose depends on your dogs personality. Their characteristics are different so what works for one may not work for the other. Make sure you test out different methods to find one that works best for you.

Which dog breed has the gentlest/softest mouths?

As we now know dogs bite especially when stressed or aggressive. These are some of the breeds that are less likely to bite unless provoked.

  • Canine Labrador retriever
  • Golden Retriever
  • Boxer
  • Spaniel Cavalier King Charles
  • Newfoundland
  • Collie
  • Bernese Mountain Dog
  • French Bulldog
  • Beagle
  • Irish Setter

When provoked these dogs will still bite. Nevertheless they tend to be calmer breeds and would not bite as much. In comparison to other dog breeds these breeds are very easy to train on what to bite or not bite.


The bite force is measured by how much your dog bites per square inch. The force of each bite may vary depending on many conditions. A dogs bite when playing is very different from its bite when it is angry. Therefore the bite force must be taken into account when measuring. Because of this most of the numbers are averages. Because these numbers cannot be very precise and specific.

They are generally good house dogs due to their intelligence and playfulness. It is important to understand their behavior well in order to take proper care of them. You should train them early since they are very playful dogs. If you do not train them they could cause problems in the future.

No matter which breed you choose the most important thing is to know how to take care of your pet.
