Rottweilers and Kangals are native to two remote places on the planet.
It may seem that these two breeds have little in common, but the fact is that they have many similarities and can perform the same tasks.
Kangals are native to the Anatolia region of Turkey.
Despite Kangals being slightly larger than Rottweilers, the Rottie makes up for this by packing a huge amount of weight when you take their athletic frame and height into account.
Kangals range from 25 to 31.5 inches (63 to 80 cm) in height with a weight of approximately 90 to 150 lbs (41 to 66 kg).
The smaller competitor, the Rottweiler, comes from Germany.
Male individuals are between 61 and 69 cm tall and weigh 50 to 60 kg.
Females are 5 cm shorter and their weight ranges from 35 to 48 kg.
Both dog breeds are fierce protectors of what they consider to be their own dog breed or part of their pack.
Rottweilers are more family and home protectors, while Kangals are better at protecting farms and livestock. In inverted conditions, both varieties can perform well.
Without early socialization and proper introduction to strangers, both dogs can become very confrontational.
This is not a desirable characteristic, because these breeds are large and difficult to handle.
How is bite force measured in Rottweilers and Kangals?
Bite force in Rottweilers and Kangals is measured by electrical stimulation of the jaw adductor muscles in anesthetized dogs or by calculating the forces produced by the anatomical structures responsible for biting using mechanical equations.
Bite force is simply the force used to place the jaw on something or someone.
In dogs, the unit for measuring this power is called PSI (Per Square Inch).
This scientific unit is used to describe the pressure exerted by one pound on an area of 1 square inch.
Sometimes it is also called pound-force per square inch or simply pounds per square inch.
In vivo studies of bite force in dogs
There are few in vivo studies that tested bite force in anesthetized dogs using electrical stimulation of the muscles.
In one, the test was conducted on three breeds believed to be capable of causing major damage to their jaws: German Shepherds, Pit Bull Terriers and Rottweilers.
The Rottweilers had the strongest bite of all three, but this test cannot be considered completely accurate because some factors influence the bite force but cannot be implemented in the tests:
- The stimulation of the muscles cannot produce maximum voluntary contraction
- Lack of chewing enthusiasm in the awake dog
- Lack of awake personality during testing
If you’re wondering why no one uses guard dogs to test bite force, it’s because canines don’t know you’re asking them to bite with everything they’ve got.
The in vivo studies only showed a positive correlation between the size of the dog and the bite force.
In vitro study of bite force in dogs
The most accurate and widely used numerical tool for solving complex problems in animal biomechanics is the FEA (Finite Element Analysis).
FEA enables clarification of the bite force by building, loading and validating the skeletal models via a computer system.
Factors that influence bite force in dogs and humans include:
- Skull size (larger size, stronger bite)
- Skull shape
- Mouth pain and periodontal disease
Brachycephalic breeds generally have a higher bite force compared to dolichocephalic dogs, except for small brachycephalic breeds and extremely deformed dogs. skull shapes.
Of course, any health problem that affects the teeth, mouth, joints, and muscles can negatively affect bite force due to the associated pain and discomfort.
Rottweiler bite force
Rottweilers have a calculated bite force of 328 PSI. This is almost twice the force their body weight exerts on a surface. Of all dog breeds, Rottweilers are believed to have the second strongest “closing” bite (Pit Bull Terriers are first).
The locking bite or locking mechanism of the jaw in dogs is just a big myth. Their hinge joints that hold the jaw allow the mouth to continuously close and open.
No ratchet mechanism would simply lock the jaw in place, there is no such thing as a true locking of canines.
Exactly why Rottweilers are credited as part of the closed jaw dog family is because of their enthusiasm when biting.
Their strong determination is just a behavioral trait that helps them hold on to something they bite to cause more damage and thus eliminate the threat.
Rottweilers rank 12th on the scale of dogs with the strongest bite force.
Slightly higher than them are the Leonberger and the Japanese Akita Inu at 399 and 400 PSI respectively and the Siberian Husky is a step lower at 320 PSI.
Dogo Argentino and Dogo Canario have a speed of about 500 PSI, while the bite force of the Bandog and Cane Corso is almost twice as strong as that of the Rottweiler.
Myths about Rottweiler bite force
There has long been a myth that the bite force of Rottweilers is 2,000 pounds per square inch (PSI).
This information was mentioned repeatedly at dog behavior conferences and even spread among the veterinary community.
Today we know that the bite force of Rottweiler dogs is much less than 2000 PSI, but how did this misinformation come about in the first place?
Probably traced back to an experimental work done at Guelph University of Canada and published in the Journal of Anatomy in 2008.
The team used in vivo and in vitro methods and concluded that bite force is different in the anterior and posterior portions of the jaw.
The rear section produced a pressure of about 568 pounds, compared to the 170 pounds at the front.
Still, that’s a far cry from 2000 PSI.
However, the results of this particular study were presented in Newtons rather than PSI.
The average bite force of the dogs in the study appears to be around 2000 Newtons and this is probably how the myth came to life.
One Newton is equal to 0.22 pounds of force, so 2000 Newtons is equal to approximately 450 PSI, which is close to the actual bite force of Rottweilers.
Kangal bite force
With an astonishing bite force of 743 PSI, the Kangal claims the number one spot on the dog bite force scale. That’s almost more than twice the bite force of Rottweilers and 3 times stronger than the Doberman Pinscher.
Although Kangals can do the most damage of any dog out there, they are surprisingly quite stable, especially around children.
They require intense training and if you do it right, you will get an incredibly strong companion.
Kangal bite force compared to wild animals and humans
The wolf’s bite is one of the most feared forces in nature.
They have very strong jaws and sharp teeth that allow them to hurt their prey and other predators.
Wolves are probably the biggest threat to Kangals and the livestock they protect.
a test conducted by National Geographic revealed a bite force of 406 PSI from a specimen that is strong and large.
However, other recordings conducted showed that a wolf’s bite can reach 500 and even 600 PSI.
Even though that’s a lot, it’s still no match for the corrosive power of the Kangal.
The Jaguar can produce the strongest bite with an astonishing 1500 PSI among all cats.
The Bengal Tiger comes in second with 1050 PSI and the king of the jungle, the Lion has a bite force of approximately 650 PSI.
The Great White Shark and the Saltwater Crocodile are the animals with the strongest bite force of approximately 3700-4000 PSI in the world.
Humans have a bite force of about 160-165 PSI because our survival does not depend on our bite force, but that is not the case with wild dogs and cats.
So who has the strongest bite: Kangals or Rottweilers?
The Rottweiler’s 328 PSI is no match for the powerful bite force of the 743 PSI that Kangal has. The only thing that makes the Rottweiler extra dangerous is its amazing determination which is responsible for the jaw lock behavior.
Both breeds are very hardworking and very courageous.
They can work relentlessly for hours, causing serious harm to people and other animals if they feel the need to attack or protect.
When do Rottweilers and Kangals bite with the greatest force?
If your dog is in full health, he will produce his strongest bite when he is in a life or death situation. Dogs are not natural killers and have no intention of hurting anyone or anything unless their lives or those of their loved ones are in danger.
Sometimes they bite just enough to scare the opponent without causing major injury.
However, in cases where they are seriously cornered and/or outnumbered and see no other way out, they will use the full force of their jaws.
