Almost all yorkie pups start out like Ceasar, lol, they resemble little rottweilers when they're little!!! The tan on the head gradually "spreads" and the whole face becomes tan (in most instances) and the grey hairs start appearing in amongst in the black. A few do ffffdbxfof yeadrtrs, epecially if you keep the coat long. If you clip the coat at 6-8 months its easier to see the change as the new colour comes in at the roots. Here are some pics of Mika you can see the change, she is still only 6 months old and has a way to go, just recently noticed a silvering effect on Mika's back.

Most recently at 25 weeks you can just about see some lighter hairs mingling in with dark, Mika has lovely rich black colouring but I'm pretty sure she will eventually have the blue steel and gold colouring that is standard.

I hope this helps to answer your question, I'm sure your baby will change alot as he grows. Thats one of the most exciting parts of having a yorkie around, its like watching your kids grow, they change sooo much far too quickly but its lovely to look back and remember. So make sure you take lots and lots of pics
