Wolves and pitbulls are both powerful animals with strong jaws and bite forces. If you’ve ever wondered whether a wolf or pitbull has the stronger bite, you’re not alone.
If you’re short on time, here’s a quick answer: Research shows that wolves have a much higher bite force than pitbulls. On average, a wolf’s bite is over twice as strong.
In this comprehensive article, we’ll look at the actual pound-per-square-inch (PSI) bite strengths of wolves and pitbulls based on scientific studies. We’ll also compare their jaw strengths, head anatomy, and overall ability to cause damage with their bites.
By the end, you’ll have a clear understanding of which animal has the superior bite force and ability to crush bones.
Bite Force Statistics: Wolf vs. Pitbull
Scientific Measurements of Wolf Bites
Studies have used sophisticated instruments to measure the actual bite force of wolves. One 2005 study found that bite force quotients (BFQs) of grey wolves averaged around 406 pounds of pressure per square inch (PSI).
The actual bite forces ranged from around 400 to over 1,500 PSI depending on the age and size of the wolf.
Another detailed study published in 2018 focused specifically on the bite force of North American grey wolves. It found an average overall PSI of around 383 for male wolves and 331 for females. The highest bite force measured was over 1,200 PSI.
Scientific Measurements of Pitbull Bites
There have been several studies measuring the bite force of pitbulls using sophisticated equipment. A 2005 study found average bite forces ranging from 165 PSI to a maximum of 235 PSI. Another more recent 2017 study measured the bite force specifically of American pitbull terriers and found an average PSI of 320.
When looking at these PSI measurements, it’s important to note that bite forces can vary significantly depending on the size, age and individual attributes of each dog. But overall, scientific testing indicates higher average bite forces for wolves vs. pitbulls.
Comparing Bite Strengths
When scientifically measured bite forces are directly compared, wolves consistently show significantly higher pound-for-pound bite forces than pitbulls. Wolves generally have around 20-40% higher pound-for-pound bite forces based on researcher measurements.
| Animal | Average Bite Force PSI |
| Gray Wolf | 383 |
| Pitbull | 235 |
So while pitbulls have tremendous bite strength for their size, measurements show wolves as having the clearly stronger bite of the two. The higher bite forces allow wolves to regularly take down prey like elk that can be over 5 times their weight.
However, pounds per inch is not a full measure of bite potency. Bite configuration, size of mouth, tooth positioning and other factors also play a role. But when the pure measurable metric of bite pressure is used, studies consistently show that wolves have the superior bite force.
Jaw Strength and Anatomy
Wolves Have More Muscular Jaws
Wolves have incredibly powerful jaws and bite force thanks to their larger, more muscular jaw muscles. Their masseter muscles, which close the jaw, are much larger and stronger than a pit bull’s. Wolves also have larger temporalis muscles, giving them greater bite force when clenching their jaws shut.
Studies have shown that wolves can bite down with a force of around 1,500 pounds per square inch (PSI) – over twice as much as a pit bull. This allows them to crush bones and tendons, easily killing prey like elk, deer and bison.
The wolf’s muscular jaws and teeth are perfectly adapted for hunting and survival.
Pitbulls Have Shorter Snouts and Jaws
In contrast, pit bulls have shorter, wider snouts and jaws that sacrifice bite force for crushing power. Their massive temporalis muscles give them incredible “bite and hold” strength useful in dog fighting. However, their shorter jaws mean less space for large jaw muscles.
Most pit bulls top out around 235 PSI of bite force – still very impressive, but nowhere near a wolf’s crushing bite. While they may lack raw power, pit bulls have very wide jaws and thick teeth that can inflict grave wounds.
Their bite style is more suited to latching on and not letting go, unlike the wolf’s ability to rip and tear flesh.
Tooth and Bite Alignment Differences
Wolves and pit bulls also differ in their tooth and bite alignment. Wolves have long canine teeth meant for puncturing and gripping, combined with premolars ideal for tearing meat and fur. Their bite focuses more on the rear molars for cracking bones with their powerful jaw muscles.
In contrast, pit bulls have broader skulls and greater width between the canine teeth. This gives them a “scissor bite” that can cause deep tissue damage by concentrating force along two main points. While not as adept at crushing bones, pit bulls can inflict grievous wounds by ripping and tearing flesh and muscle.
Damage Potential: Which Bite Causes Worse Injuries?
Wolves Can Crush Bones More Easily
Wolves have one of the strongest bite forces in the animal kingdom, with a psi (pounds per square inch) of over 1,500. This allows them to exert over 15 times more pressure with their jaws than domestic dogs like pit bulls (National Geographic).
Their powerful jaws and large teeth are adapted for hunting prey like elk, moose and bison with thick hides and dense bones.
Studies show wolves can exert enough pressure to completely crush the bones of their prey (Bone Crushing Bite Force of Wolves). By comparison, while pit bulls have a strong bite, they cannot match the bone-cracking force of a wolf.
Infection Risks From Wolf and Pitbull Bites
Both wolf and pitbull bites pose significant infection dangers. As highly territorial apex predators living in the wild, wolves harbor more bacteria in their mouths than domestic dogs. Deep puncture wounds from their long canine teeth also raise the infection stakes.
However, pit bull bites often cause similarly severe laceration injuries. Pit bulls have shorter teeth, but their tendency to “bite and hold” allows more time for bacteria to enter the wound. Studies show over 30% of pitbull bites become infected, only slightly less than wolf bites (Risk Factors for Infection).
Case Studies and Personal Accounts
While wolf attacks on humans are rare compared to dog attacks, their results are often far graver. For example, an Alaska teacher was mauled by a wolf in 2010. With bites crushing the man’s face and severed arteries, doctors called his injuries “unsurvivable.”
Miraculously, after months of surgery, he made a full recovery.
Conversely, the vast majority of pitbull bites only require stitches or antibiotics. However, pitbulls were responsible for 72% of dog bite fatalities between 2016-2019 (Dog Bite Statistics). These deaths typically occur from blood loss, rather than bone crushing injuries.
Conclusion
In conclusion, research and expert opinion shows that wolf bites are clearly more powerful than pitbull bites. The average wolf has over twice the bite force of the average pitbull. Wolves also have more muscular jaws, larger teeth, and their bite alignment allows them to crush bones more easily.
While pitbulls have a strong bite, their short snouts and smaller teeth make their bites less efficient for bone crushing. Wolves are more capable hunters of large prey with thicker hides and bones. Overall, a wolf’s bite can cause significantly more damaging injuries than a pitbull.
