Top 10 Dog Breeds: Which Dog Has The Strongest Bite?


In many countries, dogs are the most popular choice for a pet. They provide security and joy to their owners, and they are often a valuable addition to the household. But no matter how sweet and cuddly a dog may be, we have to understand that along with raising them; there comes the possibility of danger. Even the nicest of these furry friends can bite, especially when provoked.

No accurate statistics are available regarding the dog bite occurrences worldwide. However, studies show that dog bites cause millions of injuries annually. In the United States alone, studies reported approximately 4.5 million cases of dog bites each year. About 800,000 of these result in having to seek medical care.

These are somewhat alarming statistics. However, when you have adequate information, these numbers get a lot less scary. Understanding why dogs bite and which breed to look out for are crucial factors in controlling, if not entirely preventing it from happening.


What Is PSI?

To gauge a dog’s bite force, we will be referring to it as PSI. It measures the amount of strength a dog can release through their bites. PSI stands for pound per square inch. It is a unit that calculates pressure released at any given point. It is a standard system which is quite easy to understand.

This unit can vary depending on several factors such as the mood of the dog, the substance under attack, and of course, the dog’s breed. The average psi of dogs is somewhere between 230-250 PSI, but it can get higher for some breeds.

The bite strength can vary. It can differ according to the size and bulkiness of the dog’s body. It also depends on their head and the size of the dog’s jaw. In other words, the higher the PSI, the stronger the bite.
