The proper Catahoula is not aggressive toward people. He is wary of strangers but never shy. With family members, he is loving and protective. Males can be aggressive toward other male dogs, and Catahoulas in general work aggressively, a necessity in rounding up unruly hogs or cattle. Their instinct is to track and herd game, and if that isn’t an option for them, they need some other outlet for their energy. Catahoulas are excellent watchdogs and will bark a warning or otherwise go on alert at the approach of strangers. Treat them firmly but fairly. They do not accept mistreatment or physical abuse.
