bulldog vrs cur

Like everybody else has said, cur dogs, hands down seem to start more fights. People are amazed that I can crate two male pits together & not a peep out of them. They know what their job is.
On the other hand try putting two male curs in the same crate & it sounds like a chainsaw in there.
Dont have any curs at the moment but my plotts from 6 weeks old, all eat in the same pan & if I hear a growl out of them, they get a whack. that goes for bulldog pups too. They all learn to eat together & fighting is not tolerated.
Like charles said, a lot of it is owner error. I have seen dogs out of the same litter as mine, when they were turned loose wanted to fight. Life is to short.
