I want Khloe to bark sometimes because she is a great alarm, but how do I get her to calm down the barking. To me she barks excessively. When you tell her to be quiet she barks back like she is talking back to you. And I am also observing that she wants to nip your pants legs now when she gets in this barking frenzy. Help what should I do? She is 6 months and I don't want her to be a terror.
