When discussing which dog breed has the strongest jaw, it is important to keep in mind that this is a rhetorical question that cannot be answered in a definite way. The strength of a dog's bite will vary from breed to breed, animal to animal, and even circumstance to circumstance.
Bite Force
Bite force is the scientific term for the measurement of the amount of pressure in a dog's bite. Obviously, the greater the pressure a dog can exert, the more potential for damage there is to someone (or something) that is bitten. There are several factors that determine bite force, but scientists agree that the size of a dog's head has a lot to do with the amount of pressure it can exert with its jaws.
The strength of the bite of a breed can't be measured with any accuracy because you can't teach a dog to bite with consistent force time after time. The bite will be different each time it is measured, and each dog will have a slightly different measurement. It is important to keep in mind that when the bite force of a breed is discussed, it can only be in a general way.
Trained dogs typically have a higher bite force than untrained ones. A human averages 120 pounds bite force.
Determining Which Dog Breed Has the Strongest Jaw
Dr. Brady Barr of National Geographic (Dangerous Encounters: Bite Force, 8pm est 8/18/2005) did several tests of bite force with numerous animals, including dogs and wolves, to see which had the strongest jaws and the worst bite. Not surprisingly, the wolf was the canine with the most powerful bite, measuring 406pounds of pressure. A wolf can, when it is protecting itself, inflict a bite that carries up to 1,200 pounds of pressure.
The top five domesticated breeds thought to have the strongest jaw are all large dogs known for their bite. They are generally the same breeds attributed with the highest rate of attacks on people, and they are often listed as dangerous dogs.
Pit Bull
The Pitbull has become a breed synonymous with strong jaws, biting and danger. While this dog does not have the highest bite force of the dogs National Geographic tested, it is one of the top four. The Pitbull bite was measured at 235 pounds of pressure. It is the most highly recognized breed for jaw and bite strength.
German Shepherd
Although the German Shepherd was originally bred as a herding dog, it has been used as a guard and police dog with good reason. This is a powerful and intelligent breed. The German Shepherd's bite measured 238 bite force, just slightly above the Pitbull.
Rottweiler
The Rottweiler, or Rottie as it is often called, has a huge head and large jaws. This breed bit with 328 pounds of pressure. The Rottweiler is considered the second most dangerous breed of dog; the Pitbull is number one.
Doberman
The Doberman is a highly energetic dog that can be very aggressive. The bite force is reputed to be 600 pounds of pressure; however that seems to be largely unsubstantiated.
Mastiff
Many breeders say that the Mastiff has the strongest jaw. Reportedly, the Mastiff has a bite force of 552 pounds. If true, this would make it stronger than any other domesticated dog on record.
Strongest Jaw
To answer the question regarding which dog breed has the strongest jaw is difficult because there are so many variables. Of the dogs that have been scientifically tested and recorded, the Rottweiler appears to have the strongest jaw. Remember, this will vary from bite to bite and animal to animal.
If the rumors are true, however, the Doberman has the strongest jaw of all of the domesticated breeds.
