My Coco is cotton coated also. I shave her body myself (7 FC blade) before every bath (2-3 weeks in winter, 1-2 weeks in summer) and leave face and legs longer. She gets professionally groomed 3-4 times a year when her leg hairs get too long. A fresh cut also gives me a guide when I do home groom
. I pay $65 at Petsmart and she gets the works. I don't do nails either, so they do go in for nail grinding every 4-6 weeks or so.
