You hit the button on the keys.
Keith, your German shepherd friend, sits there, waiting for something to happen, and at first it seems like there is no reaction. Then the dog suddenly whines and rolls onto his back.
Your eyes widen as you see the German shepherd's crotch start to shimmer and shift about the sheath, which a bit of red rocket is still poking out. After the shimmering stops however, both the rocket and sheath, even the fuzzy balls, are gone. Keith pokes down his head to his crotch, sniffing about, then looking up at you, giving a long whiiiiiiiine as if asking where his little friend went.
You look between the keys and Keith, kneeling down to get a closer look, then blushing as you notice what happened. "Ur...I think you turned into...a bitch."
Keith start barking at you angrily, causing you to fall over. "Hey! Hey, calm down, Keith! I'm still getting the hang of these keys. I mean, unless you want to stay a bitch, stop acting so...bitchy."
Keith stops barking and gives another whine, his tail tucked between his legs, covering his new female parts.
"OK. Don't worry. I just need to take a step back and figure out how these keys work." You wonder if Keith's new female demeanor would make him more trainable. Maybe Keith wouldn't mind taking a job as a trained dog. Definitely would help with his job situation...
While you were distracted, a someone with a yellow Labrador has walked up, and the Lab promptly sticks his snout against Keith's butt, causing Keith to yip and scamper behind you as he growls at the wagging Labrador. You can see the Lab is interested in Keith considering the Lab's rocket sticking a few inches out of his sheath as he walks away with his owner. You suddenly wonder if your German shepherd bitch friend might be in heat.
You figure you should fix him soon before Keith finds out in a more direct way. However, you're still not sure how the keys work. Should you try to fix him now, or go home and figure it out there? You're not sure what strange things may happen if you continue using the keys willy-nilly.
