I believe if you have a base model with nice clean topology and you use a multires modifier to sculpt your fur, there shouldn’t be a problem for posing him and getting all the 30 poses from just that model. With the multires modifier you can sculpt all the details and pose him and modify the base mesh if needed. But it is insane to have to sculpt the same thing 30 times, don’t take that approach. Make a simple test to see if the Multires approach works.
