What Dog Has The Strongest Jaws?

In much the same way that a dog's aggression will have more to do with its environment and upbringing than its breed, its jaw strength will depend very much on its lifestyle.  Whilst it could be assumed that pitfalls or Staffordshire bull terriers have extremely strong jaws, a dog which regularly exercises its bite will likely have more force than one that does not.

With this in mind, there have been some studies carried out and some scientific observations made. For example, the wider a dog's jaw is, the more force it will have. A dog with a broad head and a large build will be stronger than your average German shepherd.

The mastiff has a history of being believed to be the strongest biter. It was used in gladiatorial competition in ancient Rome against lions, and one of its defendants, the rottweiller, also has an impressively strong jaw.

The current record holder, however, is the Turkish kangal. It has been recorded as having a bite equal to 714 lbs! This is stronger than a wolf and a bulldog put together, and is a result of its wide jaw and heavy build.

One thing worth noting is that a dog being tested by biting down on a pressure sensitive sleeve may now be delivering its strongest possible bite - and it would be highly impossible to determine if it was. The Turkish kangal's record holds face validity due to its jaw shape and build, but it is possible the mastiff could have a stronger bite if the dog tested simply wasn't trying as hard as it could have done!

Their I no accurate way to measure bite force/p.s.I. In a dogs jaw there are to many factors. What ever dog you favor you can find evidence to back it because testing was never reliable in the first place.

It's hard to say as nobody has tested all the breeds on bite pressure per square inch so there is no way to know. It may be some tenacious little terrier, lol.  On the few tests that have been done there were very few dogs used. What we know now is that bite pressure averages about 200 to 300 pounds per square inch give or take in our domestic dogs.
In one well known test Dr. Barr of National Geographic tested three breeds in particular, the Rottweiler, the German Shepherd and Pit Bull. The Pit Bull's bite pressure was lower than the other two. The Pit was 235 per square inch, the GSD was 238 per square inch and the Rottweiler was a wopping 328 per square inch (highest ever recorded for domestic dog).

French mastiff is real high on the list as is all mastiff breads ,,great danes and irish wolf hounds would surprise a lot of people if tested,, those russian herding molossers and the korean fighting mastiff would all do great ,, my money goes on the tibetin mastiff or the mongolian mastiff

I have a english bulldog and he is only 8 months old and I have to agree with this, a person who came over was teasing him and when he got to them there was NO getting him off, good thing he is a well trained puppy and he listened at command once I came into the room.

The mastiff has the most powerful bite force follow by grey wolf then rottie then shepperd and pitts are after them. As other people have said it all has to do with the size of the animals head.  I have had several of the dogs listed and from my experices the mastiffs are by far the most powerful eating large bones twice as quick as the other dogs

Whoever thinks its the Dogue de Bordeaux, have obviously been watching too much "Turner and Hooch, its not necessarily the size of the dogs head that counts, if this was the case, it would be the Old English Mastiff, which the current largest dog in the world, Hercules, happens to be.
I grew up with old english mastiffs in my home, but now I breed rottweilers, and in my opinion, they have the strongest bite that I know of. I have still yet to find an indestructable toy for my dogs, as they'll even destroy a car tyre between them. I would be very dubious about any dog bite measuring tests, as a dogs bite will certainly vary a lot depending on how wound up and angry it was.

Pitbulls are nice had a red nose. Rotties are nice had one at 145 and a german one at 120lbs. Had a real german shepard from berlin germany, nice do super smart. My current dogs Fila and boerboel are way stronger and either could kill any pit and they weigh 170- 195- 200 and could kill most dogs. Their bite pressures are 645 fila and 630 boerboel. The Kagal is like 715 and 20-40 lbs less weight so please do not tell me pits are the king of the bite because I have 10K that says your wrong.

I was told that the pitbull has the strongest biting force. They can also lock their jaws up too. I am not saying anything wrong about a pitbull 'cause I have 3, and they are great dogs when you treat them w/ the respect they deserve.

By answering this, I in no way am advocating the mis use of the animal by stupid ,dumb people. The dog already has a bum rap because of those stupid people. The rottweiller has a biting force of 130psi per square inch.the best dog on the planet. Most intelligent. A lot of police depts are using them because they learn faster than sheppards and listen to command better.

Rotties do NOT learn faster than German Shepherds in general. German Shepherds are ranked the third most intelligent dog based on how fast they learn. They also lead the way as police dogs. German Shepherds account for over 8000 deputy dogs. While Rotties do have the most powerful bite, German Shepherds are second. Rotties do more than 130psi. They have 328psi. German Shepherds have the capibility to exert 238 pounds of pressure. A human can bite up to about 160psi at max clenching.

Also, Rotties are NOT the most intelligent. That honor goes to the Border Collie followed by the poodle, then the German Shepherd. Rottie are at the 9th most intelligent.

I just want people to get factual information, I'm not trying to call Septic a liar or start anything. I always do some research before I blurt out what I THINK may be correct.

Right about the intel of the dogs, and the (psi) on the rotty and german shepard. The strongest jawed dog is the Mastiff with 556 psi. Thats stronger than the grey wolf. As far as other strong breeds the american bulldog, boxer, and the bull mastiff.

Actually,...if you do your homework, the Rottweiler has the strongest bite force with a jaw pressure of 3000 per square inch, followed by the german shepard. These "pit bulls" are derived from English Bull Terriers that are known for locking they're jaws while biting, doesn't really make a difference tho, unless you are an idiot that thinks having the meanest dog is cool.

The Strongest dog Jaw power in the world is an adult hyena, its bite is capable of biting equivalent to 800 lbs. Of pressure and can be used to crush the bones of dead animals.
Hyena's have extremely strong jaws and a very powerful digestion system with highly acidic fluids. This makes them capable of eating and digesting their entire prey - including skin, teeth, horns, hooves and even bones. And i think breeds of bulldogs would be the poweful jaw power.

No animal has a lock jaw, it is impossible, stupid and ill conceived. There is no dog in the whole world that has over 1000 psi's
