I'm not knowledgeable enough to make an informative statement.

This dog has a horrible under bite. Combine it with his color and he looks like a Pug on steroids. Jacked up mouth and head.

In several breedings has thrown some of the most perfect scissor bites one would ever see. Muzzle lengthened and all.

With that said, I would guess recessive, at least in this dog.
