Pet Pose Tutorials?

Hey there! I'm currently making a pet pose pack and I can't for the life of me figure out how to move around the pupils, close the eyes, or really move the areas surrounding the eyes for that matter! are they the same as with human sims? I'm honestly thinking of just copying closed eyes from the sleeping pet animations/rigs by EA, and adjusting afterwards...

What I'm looking for is any advice/tutorials specifically about posing pets unless the process is exactly the same
