Chihuahuas are one of the smallest dog breeds in the world. They’re tiny, cute, and loving, which is why so many people decide to become their owners.
However, aside from their indisputable cuteness, Chihuahuas also have a reputation for being very aggressive. After all, they’re the star of many internet memes featuring an infuriated chihuahua showing its teeth.
Chihuahuas are also said to have a very strong bite force.
But is there any truth to it? If you're wondering how much damage a Chihuahua bite can do, here's everything you need to know about Chihuahua jaw strength and bite.
What is the bite force of a Chihuahua?(in PSI)
If you’ve already done some internet searches to find the answer to this question, you may have noticed that the bite force of a Chihuahua is rumored to be a whopping 3900 PSI (pounds per square inch).
However, after careful analysis, we’ve come to the conclusion that this number is, in fact, just a rumor.To understand why this number is astronomically high for such a tiny dog, first, it’s essential to learn how the bite force of a dog is measured.
The bite force of dogs is measured in PSI (pounds per square inch), and it varies greatly, depending on three main factors:
The size of the dog
The strength of its jaw
The shape of its teeth
The bigger the dog, the more powerful its bite. For domestic dogs, the range is up to 200 PSI on average. The more powerful breeds like Bulldogs and Rottweilers can exceed 250 PSI, but the strongest dogs, such as Mastiffs or Kangals, can exceed 500 PSI.
With that said, a bite force of 3900 PSI would require the dog to have a huge head and an extremely wide jaw. However, this is not the case with our tiny friend since Chihuahuas are one of the smallest dog breeds alive.
Chihuahua bite force in psi vs. other breeds
Although researchers haven’t examined every possible dog breed for its bite force, they have come up with a list of over 20 dogs with the highest bite force. Here are the 10 strongest ones with their estimated bite force:
Kangal - 743 PSI
Bandog - 730 PSI
Cane Corso - 700 PSI
Dogue de Bordeaux - 556 PSI
Tosa Inu - 556 PSI
Mastiff - 556 PSI
Presa Canario - 540 PSI
Dogo Argentino - 500 PSI
Wolfdog - 406 PSI
Leonberger - 399 PSI
Malinois - 195 PSI
Chihuahua - 100 PSI
Chihuahua bite force in PSI vs. other animals
For further comparison, let’s analyze the bite force of different animals. Here’s a list of 5 animals with the strongest bite force:
Nile crocodile - 5,000 PSI
Saltwater crocodile - 3,700 PSI
American alligator - 2,125 PSI
Hippopotamus - 1,800 PSI
Jaguar - 1500 PSI
If the Chihuahua bite force were really 3900 PSI, it would mean that this tiny, cute dog bites stronger than a saltwater crocodile.
But have you seen the jaw of a saltwater crocodile?! We’ll leave it to your imagination.
What is the actual bite force of a Chihuahua?
So, what’s the actual Chihuahua bite force in PSI, then?
The truth is, it’s hard to say. In fact, the PSI never accurately measures the bite force of a dog, simply because it’s impossible to know if the dog is biting with all of its strength.
Chihuahuas are tiny dogs, with most weighing less than six pounds and only a few growing to more than ten pounds. They're known for shaking and shivering, as well as for being delicate and prone to injury.
Their small size also means that their bite force isn't very strong
— much weaker than that of a German shepherd or even a large cat like a lion or tiger.
Their reputation for being fierce fighters is largely undeserved, and they're more likely to run away from an intruder than attack them. It's hard to say what the bite force of a Chihuahua is because there haven't been any actual measurements made, but it's probably no more than 150 pounds per square inch (PSI).
Has a Chihuahua ever killed anyone?
There is no recorded instance of a Chihuahua killing anyone.
However, this does not mean that Chihuahuas are not capable of causing serious harm. While Chihuahuas may not be deadly, they can certainly pose a serious threat to both humans and other animals.
One question that often comes up in discussions of dog bites is whether Chihuahuas are more dangerous than other breeds. While it is true that Chihuahuas are responsible for a disproportionate number of bites, it is important to put this statistic into context.
When compared to other breeds, Chihuahuas are actually less likely to bite and cause injury.
In fact, the vast majority of Chihuahua bites do not require medical attention. However, Chihuahuas are more likely than other dogs to bite in situations where they feel threatened or anxious. This means that it is important for owners of Chihuahuas to be aware of their dog's body language and to take steps to prevent stressful situations. While Chihuahuas are not inherently dangerous dogs, they can be a risk to both children and adults if they are not properly cared for.
In fact, Chihuahuas are responsible for more human fatalities than any other dog breed.
However, it is important to keep in perspective that Chihuahuas make up less than 1% of the entire dog population, so their overall risk to humans is relatively low. In comparison, pit bulls are responsible for far more human fatalities, even though they make up a much smaller percentage of the dog population. Ultimately, any dog can be dangerous if it is not properly trained or supervised, regardless of its bree
Chihuahua bite force FAQs
What is the bite force of a Chihuahua?
The average Chihuahua has a bite force of about 5 pounds per square inch. This is enough to cause serious damage to an intruder or another animal.
Is a Chihuahua bite painful?
Yes, Chihuahua bites can be painful. This is because Chihuahuas have very sharp teeth that are designed for puncturing flesh. In addition, Chihuahuas often bite in a "scissor" motion, which cuts through skin and tissue. As a result, Chihuahua bites can cause serious injury, including nerve damage and infection.
What to do if a Chihuahua bites you?
If you are bitten by a Chihuahua, it is important to seek medical attention as soon as possible. The first step is to clean the wound with soap and water. You may also need to apply pressure to stop the bleeding. Once the bleeding has stopped, you should cover the wound with a sterile bandage. If the bite is more severe, you may need to get stitches.
Is a Chihuahua bite worse than a Pitbull bite?
Both breeds can deliver a powerful bite, and the severity of the injury will depend on a number of factors, including the size and weight of the dog, the force of the bite, and the victim's individual response to the bite. In general, however, Pit bull bites are more likely to be serious due to the strength of the breed. Pit bulls have been bred for their fighting ability, and their powerful jaws can inflict serious damage. In contrast, Chihuahuas are not typically aggressive dogs, and their smaller size means that they are less likely to cause serious injury with their bites.
