Mylo is three months old and he is a chihuahua/crap-zu mix. When i got him at 10 weeks he was all white. Now he is getting a brown line all the way down his back and tail. He also is getting a white/black face and there is a distinct line on his head.

DO you mean a Chi/Shih tzu mix? :lol:
I know Shih tzu can change their colors. I am on a forum where this lady had a fairly dark tzu and as she would get him groomed he would come back lighter and lighter until he was snow white :shock:
