Noctisardor Bypass is your mom single

They would never know about his single enlared kidney or the hole in his heart that would patch itself as he grew, or that he had four functioning ureters, but they might notice the extra teeth that would grow in behind his primary set when they erupted from his gums...

Just kidding, Gideon wasn't that messed up. Just a normal old puppy with two tails.

And quite possibly four functioning ureters.

Unaware that he was being observed by two pairs of watchful eyes, with his pugged nose unable to discern individual scents and his eyes and ears tightly sealed, Gideon began what would soon become a post-feeding ritual: he squirmed in place, grunting boorishly and paddling his nearly useless legs against the ground. Once he had formed a very tiny, very shallow divot in the earth with his mighty efforts, he flattened himself into it like a little puppy pancake, uttered a content squeak, and grew very still.

Not sleeping, merely awaiting his next feeding, snug and cozy in his little makeshift bed.
