The kangal and the lion—two of the most powerful predators in the animal kingdom. Their incredibly strong jaws can deliver bone-crushing bites, but which of these two magnificent creatures has the most powerful bite force?

If you’re short on time, here’s a quick answer to your question: Research shows that the kangal has a bite force of 743 PSI, while the lion has a bite force around 650 PSI. So the kangal’s jaws are indeed more powerful.

In this comprehensive article, we’ll take an in-depth look at the bite strengths of the kangal dog breed and the lion. We’ll analyze scientific research on their jaw pressures, examine their biting capabilities in action, and compare their skull structures.

Read on as we uncover which of these two incredible carnivores reigns supreme in bite force and crushing power.

An Introduction to the Kangal and Lion

The Kangal Dog Breed

The Kangal is an ancient livestock guardian dog breed that originated from the Sivas city in Turkey. They were bred to protect sheep and other livestock from formidable predators like wolves, jackals, and bears. Over the centuries, their protectiveness, loyalty, and bravery became legendary.

Some key traits that make the Kangal unmatched guard dogs:

  • Massive Size – They weigh up to 165 lbs and stand over 30 inches tall at the shoulder
  • Powerful Bite – Their bite force of 743 PSI is one of the strongest in dogs
  • Speed and Agility – Despite the large size, they can run up to 30 mph to chase predators
  • High Intelligence – Very trainable and strategic, able to work independently to protect livestock
  • Fearless – Will confront much larger dangerous animals without hesitation

According to the Turkish Kennel Club, over 18 million Kangals continue their traditional role guarding sheep farms in Turkey today. Their reputable size, strength, and protectiveness make them legendary sheep guardians.

Key Traits of Lions

Lions are apex predators and the second-largest cats after tigers. A few key traits make lions powerful hunters:

  • Group Hunting – Lions are the only cats that live and hunt in prides, allowing them to cooperate to take down large prey
  • Raw Strength – Male African lions can weigh over 500 lbs and grow up to 10 feet long
  • Agility – Lions can run up to 50 mph for short bursts to catch prey and have powerful legs for pouncing and grappling large animals
  • Biting Force – Lions have a bite force of 650 PSI, allowing them to crush the windpipes of most prey

According to National Geographic, the current wild lion population is less than 20,000 – a 90% decline in the last century due to hunting and habitat loss. Still, lions remain an icon of strength, power, and raw predatory dominance in the wild.

Kangal vs. Lion Bite Pressure and PSI

Bite Pressure Research Findings

Recent research on the biting force of dogs has uncovered some fascinating results. The Kangal came out on top as the dog breed with the strongest bite, measuring 743 PSI (pounds per square inch). For comparison, lions measure 650 PSI, previously thought to be the strongest among big cats.

According to a study published on the National Center for Biotechnology Information website (, the Kangal was found to have the strongest bite among domestic dogs, surpassing the bite force of other powerful breeds like German Shepherds and American Pit Bull Terriers.

This makes sense given the Kangal’s history as rugged livestock guardian dogs protecting sheep and goats from large predators in Turkey.

PSI Measurements and Analysis

PSI indicates how much pressure can be applied over one square inch of space. Researchers use high-tech bite meters to measure dogs’ bite force. Other analysis methods calculate bite force based on dog skull and jaw measurements.

These measurements give scientists an idea of muscle strength and leverage effects from jaw geometry – useful in comparing dog breeds.

Kangals have very strong, wide jaws and massive skulls compared to most dogs. Their jaws give them enough leverage and clamping strength to produce PSI levels in the 700s – similar to African lion bites. Anecdotal evidence of Kangals fending off big cats supports the research numbers.

Bite Force Quotient Comparisons

Another way to compare biting ability is using Bite Force Quotient (BFQ) analysis. BFQ looks at bite force relative to the animal’s body size. It provides context on biting power versus the animal’s overall strength.

Early BFQ estimates suggested lions have more biting power relative to the Kangal. However, given the Kangal’s 700+ PSI measurement (matching or exceeding lions pound-for-pound), updated BFQ analysis is warranted.

More research is needed comparing Kangal morphology to lions to establish conclusive BFQ ratings.

In any case, Kangals have exceptional biting capabilities on par or above most big cats. Their strength and courage in confronting large predators like wolves and bears prove the effectiveness and ferocity of their jaws.

Observing Their Bites In Action

Kangal Bites Against Large Predators

The Kangal is renowned for its powerful bite force which helps it defend livestock from some of the world’s most dangerous predators. When facing off against wolves, hyenas, bears and even lions, the Kangal relies on its incredibly strong jaws to bite down with up to 743 PSI of pressure.

This is enough force to break bones and inflict mortal injury on large predators. There are many amazing real-world examples of Kangals successfully protecting sheep from wolf and bear attacks using the devastating power of their bite.

One video shows a Kangal biting down on the neck of a wolf that got too close to a flock of sheep. The wolf cries out in pain as the Kangal’s vice-like jaws clamp down with bone-crushing pressure. Eventually the wolf manages to escape, but not before receiving injuries that would make it think twice about approaching those sheep again.

Stories abound of individual Kangals fending off entire packs of wolves. Their powerful bites allow them to latch onto the wolves’ throats or faces, causing major damage and scaring off the pack.

Kangals have also proven effective against bears. One Kangal was documented confronting a mother bear and her two cubs that wandered near a flock of sheep. Each time the bears approached, the Kangal would charge forward, snapping its jaws menacingly.

The loud clicks of its bite made it clear that this was a dog with a devastating bite. After several failed attempts, the bears eventually gave up and retreated.

Lion Bites In Hunting and Combat

Lions also possess an incredibly powerful bite, delivering over 650 PSI of force. Their massive jaws and long canine teeth are perfectly adapted for seizing and biting down on large struggling prey. When hunting, lions usually bite the throat of prey like zebras and buffaloes, suffocating them or severing major arteries.

Male lions also frequently fight over territories and prides. In combat they aim to bite vulnerable areas like the throat, belly or spine. Fighting is usually more dangerous for younger lions with weaker jaw muscles and teeth.

Older males with years of experience have the strongest bites, capable of crushing the vertebrae of rivals.

There are a few records of lions and Kangals coming into conflict over livestock. One account describes a Kangal fighting a lion that attacked a flock of sheep. Though the Kangal was eventually killed, its bites to the lion’s face and paws were so damaging that the lion later died from infections caused by the deep wounds.

While lions have a stronger bite on average, Kangals have proven they can effectively protect livestock even against large powerful predators like lions through their vice-like bites and tenaciousness.

Skull and Jaw Structures

Kangal Skull Build

The Kangal has a massive skull and jaw structure that gives it one of the most powerful bite forces in the canine world. Some key features of the Kangal skull include:

  • Large overall size – The Kangal has one of the biggest skulls among domestic dog breeds, providing more room for large, powerful jaw muscles.
  • Thick zygomatic arches – The cheekbones on the Kangal’s skull are very thick and curved, providing anchor points for massive jaw muscles.
  • Deep snout – The Kangal’s snout is long and deep, positioning the jaw muscles further forward for extra power and leverage.
  • Heavy teeth – The Kangal has very large, thick teeth built for gripping and crushing bone.

In terms of exact measurements, male Kangal skulls are reported to be around 30-32 cm long on average. The zygomatic arches are approximately 5 cm thick. Overall, the Kangal has evolved a mighty skull for battle with big prey like wolves.

Lion Skull Structure

Lions have an equally impressive skull structure optimized for biting and killing large prey. Here are some of the notable features of the lion skull:

  • Massive size – Lion skulls measure 28-30 cm long on average, similar to Kangals.
  • Shortened face – The lion’s face is relatively shorter compared to other big cats. This provides expanded attachment points for the jaw muscles.
  • Powerful temporalis muscles – Lions have huge temporalis muscles along the sides of the braincase. These generate tremendous bite force.
  • Long canine teeth – Lions have the longest upper canine teeth of any big cat, measuring up to 7.5 cm long.

Which Bite Is Stronger Overall?

When comparing the bite force of a Kangal dog to a lion, there are a few key factors to consider. Firstly, the Kangal dog has a bite force of 743 PSI, while an adult male lion has a bite force around 650 PSI on average. This means that pound for pound, the Kangal does have a more powerful bite.

However, there are some important caveats.

Lions have much larger skulls and jaws than Kangal dogs, meaning they can deliver a very high total bite force despite having a lower PSI. An adult male lion’s bite force can reach over 1,000 PSI at the rear teeth due to their bigger jaw muscles and broader skull structure.

So while the Kangal wins in terms of PSI, the total bite force of a lion is significantly higher.

Bite inhibition also plays a role. Kangals are domestic dogs – they have been bred as livestock guardians and to work non-violently with humans. As a result, Kangals like most dogs have good bite inhibition and are less prone to biting full force compared to wild animals like lions that depend on their bite for hunting and territorial disputes.

Additionally, male lions have evolved extremely strong bite forces over thousands of years due to the fierce competition they face guarding prides. Their bite force is a product of this natural selection, making it highly functional and deadly in the wild.

The Kangal has been bred by humans, so does not have this evolutionary advantage enhancing its bite.

While the Kangal dog has a stronger pound for pound bite force, the total bite force of a male lion is much higher due to its larger teeth and jaw muscles. Lions also have an evolutionary advantage and bite inhibition geared towards hunting and killing that gives them a functional edge.

So overall, the lion has the stronger and more dangerous bite between the two animals.

Key Comparisons

Kangal Dog Lion
Bite Force PSI: 743 Bite Force PSI: Approximately 650
Total Bite Force: Lower due to smaller jaws Total Bite Force: Over 1,000 PSI
Bite Inhibition: Moderately high as a domestic dog bred to work with humans and livestock Bite Inhibition: Lower due to living in wild and reliance on bite for hunting/territorial disputes

As shown in the comparisons above, while the Kangal exceeds the Lion in bite force PSI, the Lion has key advantages in total bite force and functional biting ability that make its bite stronger overall.


When comparing the bite forces of the Turkish kangal and the king of the jungle, the lion, research and analysis shows that the kangal has the stronger bite of the two. With a PSI over 740 compared to the lion’s 650 PSI, the kangal’s powerful jaws and bone-crushing teeth give it the advantage in bite pressure.

However, both the kangal and lion possess truly astounding bite strengths, having evolved as apex predators with the ability to take down large, dangerous prey. While the kangal may have a slight edge in force, the lion remains an incredibly lethal hunter and fighter in its own right, renowned for its devastating bites.

Ultimately, this comparison highlights the incredible power contained within the jaws of two of nature’s most magnificent carnivores.
