Here is a cool sketch that I got lax in uploading here. Done by the awesome  exwolf85 this is Lucky, my Zangoose from the corresponding story.

These images are to get his proportions correct, as well as any markings.

The one thing not shown in these two images is his black phallus (or his balls), but that doesn't make them any less awesome.

This one shows a nice view of him at a more relaxed stance as well as him being ready for a fight.
