Katie looked up from her now canine boyfriend to stare the old man in the eyes. She quickly slapped the old man across the face in a quick fit of rage. "What have you done?!" She looked back down at John, cautiously touching him on the top of the head as tears filled her eyes. The friendly dog simply offered a few quick licks of her slender hand. The old man raised the wand and pointed it at Katie. "Very well!" he shouted as the wand emitted another bright flash of light sending Katie awash in a strange shimmering glow.
Katie fell to the floor and screamed, her voice taking on a deep tone. Her hands suddenly cramped up as they were forced into fists. Her thumbs painfully shrank and moved up her thinning wrists to become her new dewclaws. She felt her now pointed ears begin to migrate to the top of her shrinking skull. Turning her hands over she noticed leathery paw pads swelling up on her quickly changing "paws". Each finger shrank back and grew a claw as her silver rings fell to the floor. Dark brown fur began to make its way up her ever thinning arms. She looked up at the old man with tears in her eyes. “Why?!” she managed to choke out before a dark muzzle painfully pushed away from her face. Her nose was now wet and cold and her teeth were becomming the sharp jaws of a carnivore. Katie knew what she was becomming; a German Shepherd just like her unfortunate boyfriend John. A mixture of canine yelps, whines, and human moans filled the store as Katies body continued to change species.
A large tail burst from the seat of Katie’s tight jeans sending her howling out in pain. This attracted the attention of John who made his way over to see what all the fuss was about. Katie was now on all fours, her human frame shifting to that of a German Shepherd bitch, her pants were now loose enough to crawl out of as her waist narrowed to fit her new form. Nipples soon lined her thinning canine belly as her human breasts shrank away.
Katie now felt a burning in her crotch as her fur covered vagina slid closer to her exposed anus making access for males of her new species much easier. She yelped out in pain as her body settled into its new form, her long tongue hung out of her canine maw as she panted from the change. The dogs body she now possessed began pumping canine hormones through her. Slowly her human mind began to fade away, being replaced with the mind and instincts of a dog. Her instincts told her she was in heat and needed a mate. She couldn't help but notice the stong and rather healthy looking male German Shepherd beside her, somehow she felt a connection to this stranger...
