I know that Yorkies are not suppose to shed, but Millie shed so badly that I had clumps of hair on the comb every time I combed her. Her hair got very thin and sparse, I was so worried I posted a thread on here about her hair thinning. This happen when she was 4 to 5 months old. Now, her hair is growing back and its a completely different coat. As a puppy she had a coarse and dry coat, now its so soft and silky, all that puppy hair fell out. To tell you the truth, it was worth the all the worrying I did..
