This was Billy's, mostly pink, nose in April of 2019. I prayed (on his behalf) to the god of black noses that his would in time turn black, like all self-respecting Border Collies. It didn't look right.
Well, this, below, is his nose today. His prayers were answered, and I'm pretty sure that by Christmas it'll be entirely black. There are just a couple of tiny patches to fill-in; I could almost do it myself with an indelible marker pen.
You'd hardly know it was the same dog!
