My Bijou has no hair either. She went to the groomers last month and they did put a top knot in (with all 6 hairs) LOL. It surely wasn't because she "needed" it. It was more to make me happy I think. My Bijou's scalp shows also if you brush those baby hairs on her head. I just don't think I can blame it on puppy coat. Bijou is now over 7 mos. old and still bald. But then again, someone said that some day she might just sprout a beautiful coat and shock everyone.
