The Education of Yip Barky.

Our little Pepito dog, a Chihuahua mix, kept barking at visitors. He only got worse as time went on. We had to stop living in denial. So good friends banded together with us and came up with...THE PEPSI CAN OF DISCIPLINE.

One shake along with the no-nonsense-voice command, "No bark!" has completely reformed him. Now all you have to do is say "No bark." No can-shaking necessary, but we keep it as a memento.
