The next coat is the woolly coat. Usually it's black or a dark, dark steel blue and so thick you could put a stick on your dog and make a mop out of him. To me this is the easiest coat to take care of, it just takes more time. Usually this coat needs fewer baths than the others. The greasier they get the more the coat lays down and the thinner coated they look. .
Ok lets get serious again.
How to turn a woolly into a silky. What I would suggest is to take a pair of thinning shears and get rid of some of it. Cut under the top where the part is and cut on an angle. Hold the thinning shears straight up and make two or three cuts along the strand. Never cut less than one inch from the top under the part.
