You swallow the brown pill and wait to see if anything will happen. After a minute, a tingling feeling starts in your gut. It spreads through your entire body, and you drop to your hands and knees as the transformation starts.
Brown fur grows on your arms and chest as black fur grows on your back. You start to perspire, and you pant as the fur grows thicker, spreading all over your body. You take off your clothing as your body starts to reshape. Your hands compress into paws as your feet elongate into a digitigrade. Your ears move to the top of your head as your face elongates into a snout. Finally, a tail grows from your backside. You've become a dog - a German Shepherd!
Your tail wags as you run around, looking for something to do.
