All I've ever done is had the vet's office what they call a "panty" shave for hygiene.
They are the ONE BREED that absolutely loves to be groomed because
they love the attention!!!! If Toby’s fur is really thick skip the bath at the groomer have them give him a lion cut, they leave the nice full maine,
full cuffs on their legs, a pom pom on the tail and shave the rest to the
skin!!! Picasso my boy LOVES his hair cuts he is SOOOOOOOOO much
more comfortable without all of that thick long fur!!!! I LOVE THEM TOO
he feels like a mink when petting him!!!!!
My vet’s assistants called it a potty trim. We bought a clipper and shaved the area ourselves. It paid for itself in the long run.
