My dog Pitbull 1 year guards home barks on every noise behind door. But my neighbours have small annoying dogs and they sometimes randomly bark and my dog catches up and then barking just goes on and on unless i stop her. I read before about way to train dog to guard home on command like tell her start guarding when need to and when dont say stop guarding and she stops. Can someone tell me how this type of training called so i can find more info on it? Or if you have link to article please share.
