How to calculate chihuahua bite force?

We can calculate the chihuahua bite force in PSI. But what is PSI? and how it works?

PSI stands for “Pound per Square inch”. This is the measure of the pressure applied to a given point. Actually, the correct definition of PSI is “The amount of pressure applied on one square inch of the pound”. The pressure is easy to calculate. 

Now you can assume that a chihuahua bite force is 500psi which means that a chihuahua applies 500 pounds of pressure on 1 square inch of the body.

Let’s take another example of Dobermans bite force which is 245psi. This means that he can apply 245 pounds of pressure on 1 square inch of the body.

You can apply this method to other dogs too to calculate the amount of pressure they are applying on 1 square inch of the area.

Statistics of Chihuahua bite

A study was conducted on 188 breeds bites frequency in 2009 by the Coalition for Living Safely with Dogs and Colorado Veterinary Medical Association. They came up with the following interesting facts about the chihuahua bite force.

  • Chihuahua ranks 4th in biting children

Another study was conducted in 2016 by “Dognition” company and they came up with shocking results. They took almost 4000 dog owners’ opinions and asked them about how often their dogs get aggressive.

It came up that the chihuahua became aggressive when confronted by a large dog on his way. But you need to keep in mind that the dogs included in this study were not very aggressive and the chihuahua falls in the medium category of aggressiveness.

Chihuahua bite that killed human

Although a chihuahua dog is small, it can cause the death of a human. The annual statistics compiled by says that from 2005 to 2017 chihuahua was responsible for the death of one human being.

In fact from 2005 to 2020 the chihuahua was responsible for two deaths of human beings. This can give you the idea of how dangerous this dog is and how strong the chihuahua bite force is.

Chihuahua not to bite

The second attack was made on a lady having two pit bull terriers. There is no eye witness of the scene but I think we can conclude from the above statistics that a chihuahua can cause the death of a human being.

The next question arises how a bite can cause the death of a human being?. The answer is very simple. If he bites you on the main artery of the body then you need to seek medical help. If medical help is not available then it can cause death due to excessive blood loss.

Finally, we can have evidence of the chihuahua bite force by the “Dailymail” saying:

“An out of control Chihuahua is facing a death sentence after it allegedly savaged a woman during a rampage through her home. The eight-inch long dog, called Chelsea, is said to have leaped up to bite Andrea McGann in a home in Twickenham, London. Wimbledon Magistrates Court heard Chelsea has been taken into custody and faces a potential destruction order after Fox was charged with being a person in charge of a dog dangerously out of control and causing injury.”

Although the woman was not killed, you can think of the bite. The bite was so intense that it causes the law to be enforced on the dog and the owner of the dog.

The dog bite levels

There are six categories of dog bites and they are the following:

1-Dog bite level one

In this level of dog bite the dog tries to frighten the person or another dog. At this level, he doesn’t bite the person or the animal and his teeth did not come in contact with the skin of the individual.

2-Dog bite level 2

In level two of a dog’s bite, the dog’s teeth do come in contact with the skin of the person or the animal but the skin is not punctured or the person is not harmed. 

The level one and the level two bites are the most common bites and are often reported. The dog shows aggression and is taken care of with plenty of other treatments.

3-Dog bite level 3

In this level of dog bite the skin is punctured but for not more than 1 to 4 teeth are as deep as half of the size of teeth. This behavior shows that a particular dog is a threat to humans or animals.

4-Dog bite level 4

Level four shows the dog aggression and one of the dog teeth penetrates deeper in the tissue. The wounds are worsened by the dog shaking its head. This is the warning sign that the dog should be kept in confinement and be analyzed by the expert.

5-Dog bite level 5

This dog is clearly dangerous for humans and animals. The behavior is not good and the behaviorist also confirms this.

The behaviorist also advises not to allow dogs to be free in the streets. He should be put out of the misery of confinement.

6-Dog bite level 6

The only good thing about this level is that it is very rare. the aggression of the dog is determined by the bite force of the dog. The sudden aggressiveness of the dog shows that there is a behavior problem with the dog and it needs to be immediately discussed with the behavior expert of dogs.

If you see behavioral changes in your dog you should not allow the dog to go out for a walk.
