Yeah it really depends, Oliver is almost 11 months and he still has the black puppy coloring on his coat but his face is almost all blonde. Hehe I just dropped him off at the groomers so his little black coat might be gone today!
You'll start to see his head change first, he'll look like he's going gray haha. But I think it all depends on the yorkie, enjoy the puppy look while you can! I have a feeling Oliver is going to look like his momma and be a little blondie all over!
The first pic is Oliver at 12 weeks
The second pic is him at 4 months and you can see he's starting to change
The third pic he's 8 months old (and got shaved haha)
