**An answer to this question will now be found posted here: Vitiligo: My Gordon Setter is turning white!

One of our readers submitted this puzzling issue. We would like to hear from anyone who may have an answer for why Macallan’s hair turned white in the span of a weekend? Please comment below or email us at gordonsetterexpert.com if you have seen this before or can suggest a cause.

“A friend of mine sent me a photo of her older boy, Macallan–who will be 9 in March. She said over New Year’s Weekend his face went totally white. Her vet has never seen this before, and she asked if I had. All of my kids have slowly turned white as they got older, not in just two days. It’s a very white white. I’m posting his picture here, if you know about this, let me know so I can let _____know.”

Thanks!
