I was watching an episode of "Breed All About It" on YouTube featuring Great Pyrenees. I'm fascinated by this beautiful dog that serves as a guardian, but is also gentle around children. So, I'm watching this video, and a woman states that a Great Pyrenees has a bite force around 900 PSI. That would make theirs the strongest bite in the canine world (average force). I believe that highest average bite force goes to the Kangal at 714 PSI.
Does this have any truth to it? Even lions and tigers only have up to 1000 PSI bites. Also, in some of the bite test results, wildly spaced min/max values were sometimes given. I think the GSD was rated from 450-1800 PSI (this could be the wrong numbers). What kind of bite tests give an average pressure where the max is 4x the min? And this would be a GSD's bite at nearly twice the pressure of a lions, which I find highly suspect.
This is purely a curiosity question. I'm not looking to purchase a guard dog or anything. The Great Pyrenees is attractive to me because they're beautiful and strong, but not overly prone to aggression and territorial behavior, as are some of the LGD breeds.
