Can a Chihuahua Kill a Human? Bite Force of chihuahua

Do you know what is the bite force of a chihuahua?. These cute little fidos are affectionate, timid, and loving. They are also overprotective of their owners. Hence, if you are planning to get a chihuahua then you must know what is their nature.

In this article, we are particularly going to talk about the aggression and bite force of a chihuahua. Knowing their aggression and other traits will help you to prepare yourself to train them properly. 

What is the bite force of a chihuahua?

The bite force is measured in terms of PSI (pound-force per square inch). Many research papers and articles say that the bite force of a chihuahua is 3,900 PSI. But we find it very illogical. 

The bite force of a tiger is 1,050 PSI and of humans is 126 PSI. So, how the Chihuahuas may have 3,900 PSI? There is no logic in this number. If this is, then we should protect our houses from chihuahuas.

According to our research, the bite force of a chihuahua is 100-150 PSI. You might be what is this PSI and how the bite force is measured. 

The bite force is a combined strength of jaw muscles and teeth. Both the jaws viz., Mandible(lower jaw), and Maxilla(upper jaw) apply the strength together to bite something. 

This bite force is measured in pounds per square inch or PSI. it is one of the units that are used to measure bite pressure along with Newton.

To record the PSI, an electronic device is given to the animal to bite.

What does bite pressure theory say?

Chihuahuas are small but they make sure that every person around understands not to mess up with them. The ultimate reality is that nobody knows how robust the bite force of the little Chihuahua is.

We researched over the internet and examine thru loads of research papers, but couldn’t locate particular clinical studies on how tough Chihuahuas can bite and what the Chihuahua bite force is.

It’s additionally tough to measure the strain of a dog’s bite force because canines will be mild on items you supply them except their toys or food.

Performing studies to measure their bite pressure PSI can also be tricky. Dogs won’t recognize that you want them to bite something as tough as they can.

This is why the numbers we discover online for a Chihuahua bite force strain in pounds according to a square inch or PSI are unreliable.

Final words

Looking at these beasts, we can never imagine that a chihuahua’s bite is stronger. 

In conclusion, I would say that chihuahuas do have aggressive behavior but you are safe with them. Biting is their survival instinct, but that bite will not cause you much harm. It is in your hands not to give him a chance to showcase his survival instinct. Chihuahuas do not have a strong bite like other big dog breeds.

He might bite you a bit hard but that will not be a much force for you. A dog with 100 PSI bite forces is nothing if compared to other larger dogs.
