I have a buddy that is a pit bull lover.
He always argues that a pit bull has 2000 psi bite pressure .
I have not had the heart to burst his bubble about them not having that strong of a bite, but that also they are not even close to having the strongest bite in the canine world.
I watched a program on discovery of these guys measuring dogs lions alligators sharks hippos wolves snakes,.
A dog with a wide jaw , mouth or bite can produce more pressure than a dog with a narrow one.
I think a dog named a Kengal had the most at about 700, a lion was at about 750, a great white shark was the champion with 2000.
The one that surprised me the most was a giant snapping turtle, it only had about 150, but with its jaws being like scissors, it can easily take your fingers off.
