It's because Tosa is 30 to 40 kg's bigger period would you contract into another bulldog that is 5, 10 or 15 lbs heaver no because there is only one out come and it doesn't make the larger winner the better bulldog just the smaller ones owner a damn fool a Tosa's ability is no way comparable lb for lb to the APBT as a combat dog bulldogs are in a league of there own.
