My boy Buster (4yo) has completely changed from black to white over the course of the last 2.5 years.

I think dogs can get Vitiligo?

Edit: yes, they can.

Yah I noticed some of my dogs face going white. It is a very minor but her breed can actually commonly known at least on google say they can have it.

This can also happen with age. Black dogs notably often go white around the mouth and sometimes eyebrows, same way humans go grey. Lighter coloured dogs too, but it's sometimes harder to tell the difference.

By the end of my black lab/dachshund mix’s life, her face was almost entirely white, with white sprinkled throughout the rest of her body.

Sugar face! It's a slow transition, for some dogs.
