I say "No Speak!" When it continues (it usually does), I say, "Lefty, stop being a pill." Then, "Lefty, if you don't quit it I'm going to wring your chicken neck!"

The Spoiled One has taken to barking at me when we're getting ready to go outside, especially after I get home from work and am trying to put my stuff down before getting his collar and a poop bag. It's VERY loud and annoying. My behaviorist suggested stopping all activity, folding my arms and looking away until the barking stops. It USUALLY works, though often when I start moving again, he starts barking again.
