Speaking of pit bulls, Last year I had to put my old buddy down. He was 11 years old and he just loved to fight, he would get into it with my brothers american bulldogs all the damn time. We had a routine on letting each one out in the yard and keeping them seperated, so no more fights. My dog (pumba) cause thats what he looked like lol, would wag his tail when getting into a fight with my brothers bulldogs that out weighed him by 40+ pounds, it was crazy.
He was thee smartest dog ive ever owned, slept in my bed (girl friend hated it) but I would tell her, you go before the dog lol. He loved my nephews and neices, all under the age of 4....was a piss poor watch dog cause he loved people so much.
But I have no doubt, he could handle anything that would jump out in front of him, even if it cost him his life.
Someone mentioned badgers, pit bulls years ago would destroy badgers in fights, and they were often used for this purpose in the wilds when hunting.
I think what seperates the pitbull from all other breeds is there gameness, they dont know they are short, or small, they could care less. When talking wild animals, how many of them have been attacked? They are the ones who are doing the attacking, but once faced with a animal that wont back down and keeps pressing, they will give up the fight to run and live another day.
If we look at the attacks by cougars/mt lion on people we see that they attack from behind, this gives them a advantage for not being hurt during the attack and causing the most damage quick. BUT when a cougar meets his match against two people (one being attacked and the other beating the cougar with rocks, sticks etc) the cougar will try and hang on, but then gives up and hauls ass out of there.
Never underestimate the power, heart, gameness, and loyalty of a good ol pitbull....RIP Pumba
