[2460] Canis Lupus

This is a standalone short story where the main character wakes up one day to find that he is turning into a wolf. This is my first submission so any critique is appreciated, though I'm also curious about the following:

1. Does the progression of the story make sense/seem natural? Are there places that drag on too long or aren't developed enough?
2. Is the protagonist characterized effectively?
3. Does the writer's voice come through?
4. Is the story enjoyable?

Thanks!
