I totally understand trying to deal with barking. It gives you and everyone around a MAJOR headache! Tuesdays are bad here.... the garbage truck, and tons of other people that are coming around. Taylor responds to the "Bark Can", but not always. I found if I whistle loudly he will stop for a bit. (I can do a MEAN whistle!) The thing that seems to stop him in his tracks for barking or his crazy mode is if I put my finger in my mouth, blow up my cheeks and pull it out, making a loud popping noise. (I think Grandfathers used to do this to entertain their grand babies. I was amazed! Now if I am telling him to be quiet and even put my finger near my mouth... she STOPS! Go figure!
