Moose looks like he's skating on the wood floors if we don't keep him cut.Even with my Yorkies, I shave their pads. For performance dogs with hair this is a necessity because too much hair between the pads makes it slippery for the dog. Keeping the paws neat and trimmed gives them more traction. Same thing can be said about trimming nails. While Poodle people might take that to the extreme (to keep the paws nice and "tight"), trimming the nails keeps the toes from getting "jammed" on stuff which can cause hyperexstention and ligament damage.
