Wife and I fought two 70-80lb pits. We won but I wouldn’t say it was definitive. They wouldn’t commit to a bite and hold. They almost killed our puppy. They would bite, rip and tear and jump back. They were practically impossible to get a hold of I hit and kicked them so hard but it didn’t faze them. We were just taking a walk down the road with our puppy on a leash. Thank god the owner was able to beat them back with a shovel. Wife got a nasty scar on her arm from them. It was pretty sad seeing the owner smashing their heads in.
