Issue Description:

Steps to reproduce:

1. 'Doggy Charm'
   2, Name the dog.
2. Shear ### once

Obviously it has turned into a vanilla wolf, but still got its data over its head, and you have to shear it again to remove them all.

This is normal behavior. Shearing it once doesn't all the way make the dog into a vanilla dog, but merely removes 'resets' the dog, allowing for someone to come and actually take claim of the dog.
