[quote=Bahamian]that limitation is their fight first mentality. [/quote] Aside from the fact that you live in a warm/HOT climate, this, right here, is one MAJOR reason as to why you SHOULDN'T get a CO... ESPECAILLY one from working lines. They can be VERY pre-emptive in their actions as well as HIGHLY dog aggressive. What are you planning on doing with the other 6 dogs you have? Maybe I read it wrong and you meant to say you've had 6 pits previously? Even so, I'd say that, if for no other reason than climate alone, you might want to check into Cane Corsos, Presas, Boerboels and a Filas instead of Caucasians.
