It's not the level of desire to fight as much as the power, a scrap between other breeds for 5-15 seconds(depending on your skills as a handler) can be broken up sans damage where as APBT and mixes there of more often than not are just so good that a damage free argument is the rarity. This is from my experience with pit bull rescue over the years. My male Malinois is very low on dog tolerance and my female Malinois is moderate. I would take them being DA over my pit bulls DA, I'll be honest Backup got owned both times he stupidly took on Arnold. He's not a fair fight but still it's a very different style, Arnold goes for a grab and grinds. Backup is a bounce and snapper. When we have other breed scuffles at my work I see them broken up hastily with minimal damage, I've yet to see a pit bull fight that started (actual contact) and stopped with such little damage as a scrapped cheek. I truly love my pit bulls, without fail. I just think its only fair to be honest about their behaviors or else I may be setting them up for failure. I should add, Shamoo likes to push buttons but she will avoid a fight and she is a pit bull. That said when engaged in a fight she sure can get in some nasty strong bites very quickly, often faster than she can think straight. I have an ugly scar from her redirecting accidentally (which ime is less common in pit bulls) on my leg and Denis has a nasty one on his arm from the previously mentioned recent fight (not so comically its on his sleeve arm which has made Bitework lots of fun for him lately).
