"We got a special here today. Two dogs in one bun." The vendor says heartily. "Uh... isn't that a little too much dog for not enough bun?" You ask, but the vendor only laughs in response. "Whatever you say, kid. So you want one or not?" He asks. "Sure... sure, why not." You say, handing him a bill. He hands you the double dog and you thank him before walking away.
Just before you get out of earshot, you think you hear the vendor laughing, but to can't be sure. You find a secluded bench by a pond and sit down to enjoy your hot dogs. You take the first bite and it's heavenly. Hot, spicy meat fills your mouth as you eagerly wolf down another bite. It's a shame it's already half gone. In another thirty seconds, so is the second half. Your stomach rumbles and you find yourself heading back to the vendor for another double dog. "I'll only charge ya half price this time." He says slyly, but you don't notice as you quickly run back to the bench to wolf this one down.
Some meat and bun get on your chin and you lick it with your tongue to get it off. Odd, you don't remember your tongue being that long or flat. Shrugging it off, you jog back to the vendor, panting all the way, and order three more double dogs. You find yourself able to run back to the bench much faster than before. Right as you're about to sit down, your double dogs tumble out of your hands and land in a heap on the ground.
You whine in protest and are about to reach down to pick them up when you realize you can just eat them off the ground. As you bend down, you barely notice that your face stretches out to meet the dogs, rather than the other way around. You hands feel strange as you set them down on the ground to leverage yourself while you scarf the dogs down. In fact, as you get down on your hands and knees, your whole body seems to be shifting under your clothes, changing in weight distribution, posture, and even overall shape.
But the taste of the hot dogs are too good to be distracted from. Even when you feel something poking at the base of your spine and something long and thick pushing out. Even when you feel pinpricks on your skin as something thick and warm washes over your body in a wave. Even when your ears grow pointed and migrate to the top of your head. Even when your forehead slants back and your eyes are pushed farther to the side of your head. Even when your growing body causes the clothes you had been wearing to rip off and lay tattered below you. Even when your legs shorten and fatten and your arms are rigid. Even when your hands and feet feel swollen.
As you scarf down the last bit of hot dog, you bark happily. Wait...bark? Sensing something is deeply wrong, you drag your way to the she of the pond and look into the reflecting pool. You are shocked to see a panting Malamute looking at you from the water. The vendor...he must have put something in those hot dogs!
