Transformed into a Puppy:  Danielle comes home to find her out-of-work boyfriend Damian on the couch masturbating again and decides she has to act decisively to end his problem.  Damian reluctantly agrees to be enrolled in the West Highland Kennel Club for obedience training, but resolves not to play along with anything, Locked into chastity, he undergoes a month of obedience training, including subliminal and hypnotic identity reconstruction, emerging one month later as Danielle’s obedient puppy, Fluffypoo.  

Fluffypoo has learned to sit, fetch, beg, and roll-over. He’s housebroken and knows to lift his leg when peeing during walks.  It goes without saying that he’s been completely cured of his masturbation problem.
