So Dallas really needs a heavy blanket in the winter, I'm north and he has very little winter coat. Problem is it rubs his shoulders to there is a patch on each shoulder about the a little bigger than quarter that is littler with shorter hair. I'm rubbing show sheen on it now that I have notice it has begun rubbing to try to decrease rubbing. I need him to look good for shows. Any advice to grow the hair back quicker or stop the rubbing?
