yes but you have to take the size of teh ehad in to consideration, the b igger the head... the bigger the potential. if you tested 100 rotts, 100 pits, you would find that the rotts on "average" will have the better bite force due to size of head and amount of jaw muscle they have to use at their disposal. i cant view that youtube video here but i assume its the rott vs pitt vs GSD on the bite sleeve? if so, the rott bites at around 100lbs greater than the pitbull thats a huge variation and the best of rotts wont drop that 100lbs to loose in this contest.
