I think it needs moar muscles >,..,> it'll compliment the behemoth of claws xD

speaking of fur O: I think zbrush site has some fur tutorials

its really good.
cinema and 3dmax have an hair Plugin. i am not familiar with zbrush though.
if you have the displacement map ready you can load it in cinema or 3dmax.

You can make a normal or displacement map for the model and export that + an OBJ of the model to import into Maya, 3dsmax or softimage (and likely others). Those 3 all use Shave and a haircut which once was a separate plugin but is part of those 3 programs so essentially are exactly the same.

Dealing with Fur is very time consuming to learn, can be tweaked infinitely and is very cpu intensive to render.
