Shaggy dog and the terrible itch

Shaggy Dog has a terrible itch. He scratches and scratches, but the itch just won't go away. He asks Mimi, the poodle to help. "Urgh! Scratch your back, no thank you!" Luckily, Farmer Gertie and Merv from the cafe help him - but still the Itch stays put. In desperation, Shaggy Dog runs into the Poodle Parlour for a good shampoo. Will Shaggy Dog ever get rid of his terrible itch? And if so, where will it go?
