The hair on my 12 week old newly adopted Morkie (Yorkshire/Maltese) is kind of matted. On the face it looks very silky and his legs are quite silky as well but the fur on his back is somewhat coarse or just matted. He recently had a bath and I don't know what they used to clean him and dry. What should I do to make his coat silkier and lay flatter. He is very fluffy!!
