Yes presa canario's make excellent guard dogs !!! They can decide if a person is a threat or not and treat them accordingly. Unlike breeds like the german shepherd and doberman whom are typically aggressive towards all strangers. They are generally great with everyone once they get to know them and establish if they are a threat or not. My presa is a big ham and loves most people, but I have a sister in law who is kind of a shady person and he hates her. Wont let her anywhere near the house.
