[General] How big would a midget werewolf be?
gpt
There are lots of kinds of lycanthropy, some of them come from supernatural causes. others more biological.

So instead of trying to nail down which you're talking about, I'll keep it real general.

Magical or supernatural lycanthropes will transform into a form that fulfills the curse or magic. If it is to be trapped as a wolf, then the little person will likely transform into a wolf of normal size regardless. If it is to transform into a 9 foot tall murdering force of nature, that's what will occur. 

Those types of lycanthropy don't seem to care about mass, a full-sized man becomes a wolf of smaller mass without regard to any other factor, and/or the same man can become a hulking mass of claws and flesh without being worried about where the extra mass came from.

Biological lycanthropes have to somewhat obey the general laws of physics regarding size, so instead of a man transforming into a man-sized wolf hybrid, a little person would transform into a smaller version of the same creature.

The breed when fully transformed into a wolf is always the same, some version of Canis lupus or Canis dirus, but the man-wolf hybrid's appearance and traits are completely variable from individual to individual.

I don't suppose that would change much if the subject were a little person.
