you glance over the list of animals and see "dog" and think about when you had a border collie, how it was to come home from school and pet him for what felt like forever, and how you loved him
much to your suprize, you start to see black fur growing on your legs as your feet start to warp and change "i luved that doggie!" you say with your little girl voice, then look down and notice your white feet "paws" and can't help but giggle, the fur spreading up wards, as it reaches your waist you feel a buldge and look back to see a fluffy black tail with a white tip, wagging about "hehe, it's soft!" as you giggle feeling the tail up,
by this time, your arms become covered in black fur, and your hands are now semi-paws with pads on the bottoms, white fur covering your upper legs all the way up your stomach and chest to your neck, as the fur reaches the neck your face tingles, as you feel your teeth rearange , but not to much, almost pup-like with a slightly rounded muzzle.
your face finishes pushing out as your eyes move slightly to the side of your head "i look vewy cute!" as your tounge hangs out a bit, your full head reshapes to that of a canine, the last change is your ears move to the top of your head and flop over, in classic collie fashion.
you start to feel your arms then feel the feeling and think "im petting myself!" and smile
you look in the mirror and must be no older then 3 or 4 years old!
after that you search the bag and find crayons, coloring books, some toys and pencils and paper
you reach for the wallet and get ready to head out into the world as a little collie girl!
