AS you look through the box, you spot a black and white dog costume
which turns out to be that of a Border Collie, white-tipped tail and all.
you start with the head and find it fits perfectly, almost too perfect, then you slide into the legs and the top part of the body, as you stand there looking yourself in the mirror, you then notice something odd, and feel it too!
the tail was wagging, as you turn around you start to move it around, as you touch it you jump as you feel it, you look down and see the fur squeezing your legs as you start to feel another change, your privates now covered in a sheath and covered mostly by white fur, your chest now puffing out into breasts as you then feel your privates shrinking into nothing
your face now stretches out and meets with the costume head, as your ears become more sensitive to noises around you.
the last change to happen is your legs become digitrade and your feet are now large, white paws with black claws, your hands are a cross between a hand and a paw, with soft pads on the bottoms
with in minutes you are a female anthropomorphic Border Collie
