Instructions for Using Our Dog Whistles

To blow the whistle hold it between your lips with the solid side in your
mouth. Place the tip of your tongue on the back of the whistle (solid
side) BEING CAREFUL not to obstruct the holes. Now whistle as if you were
naturally whistling with your tongue thus forcing the air you blow thru
the top hole and out thru the open front of the whistle. You will have the
tip of your tongue touching the center of the solid back of the whistle.
Pitch changes can be accomplished by moving the timp of your tongue
against the back of the whistle plus changing the curling of your tongue.
With practice and perseverance you wil be able to whistle a tune with
ease.
