hi Mitzi is 17 weeks old & the standard black & tan puppy colour, but the fur on the top of her head is growing through a light silver grey colour. The rest of her face around the muzzle area is golden. I know sime yorkes do end up grey on their head but her mum & dad both had totally golden coloured heads, which is what i was really hoping mitzi would turn out like. Is this still likely & the silver grow out or will she keep the silver? this is my first yorkie so don't have a clue but i'm sure some of you experienced owners out there can tell me how your babies changed. thanks
