This is a blue roan pup shortly after birth. You can see she looks like a black and white tri now.
You can see a gray or "blue" tint to her skin, hinting at future roan changes.
At this age you see her clear white areas.
Here is the same pup, a few weeks older. You can see how the white areas are changing.
On her little paws you see the graying, getting ready for the colour.
Here she is a few weeks later. Her colour is becoming more obvious.
You can see how her little paws are now tan, with a silvering going up her legs.
She is a doll!
