Air Collar

How I can get my Chihuahua to bark?
Well, I've had my chihuahua, Candy, for about two years, and every day is the same, it is our 6-month old Golden Retriever, barking, which is our 8-week-old Golden Retriever, barking, she sees someone walking down the street, she barks …… she even barks at the sample air.She teeth and try to complement them, sometimes stings I've tried everything to be much more in his neck, and the shock to get him to stop, I love her very much and do not want to take it to the house or put her down, so how I can do to stop it? By the way …… not really playfulness "type" and as I said before, that barks in the air too .. … she is also semi-territorial, she thinks it's "owner" of a sofa in the living room right next to the window and bite anyone (except my mom, dad and brother) if it is coming …. also defends his bed of our other dogs
Seriously, try a bark collar. They work wonders. Only shock when they bark. Tell the dog the command "Quiet" or whatever then if it persists, put it on. all you need to do a couple of times. I know, I have seven chihuahuas.
