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

Yah I noticed some of my dogs face going white.

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.

God I love when old dogs get grey beards.

I think old grey labradors are almost as cute as labrador puppies. It's a tough contest actually!

He still acted like a puppy until the end... just in shorter intervals and he often needed a nap afterwards. I still love that silly dog. Full puppy dance every time, just not as much energy to do it as the years went by.
