Pit Bulls have more bite pressure per square inch (PSI) than any
other breed. This is absolutely false.
Tests that have been done comparing the bite pressure of several
breeds showed pressure PSI (per square inch) to be considerably lower
than some wild estimates that have been made.
Testing has shown that
the domestic dog averages about 320 lbs of pressure per square inch.
Recently Dr. Brady Barr of National Geographic conducted a comparative
test between a Pit Bull, a Rottweiler, and a German Shepherd. The Pit
Bull had the LOWEST PSI OF THE THREE.
The highest pressure recorded from the Pit Bull was 235 lbs PSI. The
highest from the GSD was 238, and the
highest from the Rott was 328.
Dr. Barr states that as far as he knows, the PSI tested in the Rott is the
highest on record for any domestic canine.
What happened to the supposed 10,000 pounds PSI pressure that the
breed supposedly has??? It's a MYTH, pure and simple.

THERE HAVE NEVER been ANY TESTS done to prove that the APBT has
bite pressure PSI higher than what has been tested by Dr. Barr.
