Dog Got It!

The small dog sat quietly waiting.  Hearing footsteps he lifted his head and gave a shrill bark.  As the salesman drew near the little dog growled and lunged at the screen door. It bulged against his weight as if it would burst.  In fright the salesman ran flinging his samples aside.

Surveying the scattered mess the owner smiled and picked up the basket. Free shampoo for a year!  Good dog!
