I've read some threads about how to teach your dog not to bark (bark collars, rattling at them, etc) but I don't want to teach her NOT to bark. She only barks when people are near my door at home or if someone comes in that she doesn't recognize. (Which is great! I want to know when people are near). The problem is, I want to teach her when it's okay to back down. Like "okay, I see your concern and why you are barking, but that person is OK" but not teach her to NOT bark at all.
