Do any other owners of little puppy yorkies have concerns about their hair....Maggie's hair looks like she stuck her tail in a light socket

...None of it lays down and there are thin spots in some areas.....Is there puppy hair versus adult hair?.....OMG she looks pitiful!!!!!
Max, our 4 year old, was basically a rescued dog and has lovely hair....Maggie is a high dollar puppy and looks like a halloween costume with a precious face. My husband is bemoaning the fact that she cost so much and looks so funny

.....I love her to death but unless her hair changes we may keep her in PJ's, sweaters, t'shirts or a body cast
I thought about cream rinse....etc....but don't know if it will help...
Did any of you all have a puppy with pitiful hair that finally grew a great coat .....if not just lie to me....I need the encouragement
