Puppy Uglies?!?

So, For all of you who don't know me or my pets...my name is Ray and I have three adorable dogs Jiji a yorkshire Terrier,Bella a Maltese, and Smoochie a Golden Parti Yorkie also known as a Gold Dust yorkie. Last year I had planned to Breed my 4 1/2lb Jiji to a 5lb Yorkie named Prince. Well, my Jiji and Prince had three lovely little yorkies back on May 19th of this year. They had two lovely little girls and a diamond in the "ruff" that happens to be a little male. So, anywho it appears that my little boy is going thru what some people call Puppy Uglies and so he is looking a bit odd. For anyone who doesnt know..."Puppy Uglies" is when a puppy hasn't fully gotten all of his Fur and gotten that fluffy puffy look. "Some hairs may be longer than others or patches of fur here and there" So yeah my little male has longer hairs than others and it makes him look like he might be a mix breed but he is not he is one hundred percent yorkie but is going thru his ugly stage....Poor baby! Has anybody experience this before?
