At what age do yorkie puppy's change color. My little Jill is 12 weeks and on the top of her head you can see the roots coming out grey. Both her parents are blue/grey in color so I am sure she is destined to be that as well. I look at her hair on other parts and the outgrowth is still black. I just don't know at what age the color starts to change. Just curious. Thanks for the info.
