I like it up until the last few lines, then it gets awkward.

As soon as she turns back into a wolf I lose all spatial understanding. Where is she, where is he, where are the other wolves?

And then that last line just seems awkwardly phrased or terribly cliched

Jessica’s dialogue could use a bit of retouching, the next paragraph is a little awkward, then the conclusion just needs to be completely re-done.

I like how it opens so mundane, then cuts straight to the action.

Please take another pass at this. It’d be really good if it weren’t for the ending.

The middle was the strongest part for me. The image of her face in the jaws—and, for some reason, the phrase “thick tears”—really worked.

I didn’t quite understand the shift from “they will” and her apparent feasting. Maybe “we will” or something similar?

I agree with J.M.V. There’s a core here that could develop.

In contrast to the other opinions, I quite liked how you laid this tale out.

Her two companion wolves (the two feeding on the horse) are going to eat the man. She won’t – but her loyalties lie with the pack first. Her husband is the prey and must die.

If her husband had been her first concern she would’ve explicitly warned him and confessed her ability to change shape.

Two families run opposing paths and Jessica had to choose. She gave him the quickest death she could.

The last line implies a religious aspect to the couple – and increases the depth of her concealed condition.
