My understanding is a bull’s horns are very sharp and thier blow is harder than the bear’s sharp claws. I think the bull wins since it has been bred to fight.
Never gave my own opionin. I’ma go ahead and put five on the bull. Once the bear lands a shot the bull would go into a bucking tornado. If the bull connects with a hoove or two it would be cutains for the bear. I don’t know how accurate the bear would be able to be when the bull is in a bucking whirlwind. [xx(]
