Hi. My chiuahuah, Max, is aggressive to strangers, of course he is a 'ankle biter gaurd dog'. But it's going a hair bit too far. He's barking at everyone that comes in the house. I kinda wanna train him that when we say like. . It's ok when he barks at someone, he'll stop. can anyone possibly give me a suggestion please?

ok thanks for reading
