I don't know of any werewolf textures for the Unimesh figures yet, but there are several products for Michael 2, and the body/head textures can all be adapted for M3/V3/S3P/Freak with the Universal Texture Convertor.

Visit DAZ for the Wolfman Pak mentioned in the thread you linked, and the Marketplace here at Renderosity for Rawnrr's Werewolf Pack and Man2Wolf Texture Pack.

Daio has a Felis Sapiens product for Victoria 3 and Michael 3 over at PoserPros, if you'd like an alternative to canines. And DAZ carries the Fantasy Feline textures by Silverleif Studios for the older Millennium figures.
