Science, Biology... Will you let your kids play with a PitBull that was born and raised in captivity? Let me say this... My Cousins pit just attacked me last week, I about killed it. Wont take my son there ever again, if it would have been my son There would be one less pit in this world. My cousin is like " He is just a baby" Never did that, He is Gentle...ect.... Bullshit, Its their nature. Believe what you want about Pits, even Gorillas. I took Biology and science, Nature is Nature regardless if in captivity or not, yes, not as aggressive if tamed or raised in captivity ( KEYWORD: NOT as aggressive ) but they will still turn due to their NATURAL INSTINCT (again KEYWORD: NATURAL INSTINCTS ) Its in the books, the pros know as well as they all hint it as "They cant tell for certain"
