You take the collar out of the box. It looks very formal, like the ones used by police dogs. It comes with a note: "Just try it on..." Despite this invitation being rather odd, you decide it can't hurt to do it for once, and you slip the collar around your neck and fasten it. At first it's kinda choking, but the painful feeling quickly diminishes...partly because your neck seems to be swelling with brown fur! Your try to take the collar off but are unable to do so, as the brown and black fur spreads across your body really fast, causing a tremendous amount of itching in the process. Your feet feel like they're shrinking, and as you shake off your socks and shoes, it seems indeed that your feet have shrunken down to three-digit hind paws, your legs reforming as you watch. Now unable to stand upright, you just sit crouched on all fours as your arms and hands undergo the same process until you are completely in a stable position on four paws. Your face feels like it's stretching as well as your teeth grow and change to typical dog's teeth, your lips practically disappearing and your nose becoming black and leathery. Your eyesight goes black and white as your eyes become rounder and move a bit more to the side of your skull, your ears moving upwards and becoming large and pointy, and as it is done you manage to twitch your ears in various directions. But the changes are not quite done yet: with loud cracking your spine straightens and a brown-furred tail starts wiggling out and within moments you can swish it like it's a third arm. You have now completed your transformation into a German Shepherd...
A police officer comes by and says "Hey, ready for work?" as he straps your K9 uniform on and takes you with him on a leash. As you follow him in a trot, you wonder what you are in for...
