George has always been a plain brown TB. But his winter coat is shedding and the hair underneath is..... spotted.
He has not had a fungus or any skin problems. But these white spots are all over both sides of his shoulders and neck. I have no idea if he will have spots all over him by the time he finishes shedding out.
His brown coat is also washed out. His winter and summer coats are usually the same color, but he does have head to tail dapples in the summer.
I'm laughing because I'm putting together a blog post about MY TB turning into an Appy! My guy's white splotches are definitely Birdcatcher spots, which is probably what your guy's are too. No worries--just a little more chrome!
I noticed that when I clipped my TB a couple weeks ago that he had some dry patches of skin underneath that winter hair. I doused him a few times in Healthy Hair Care spray and most of them seemed to clear up. There were a few bite marks under there too
Anyway, his spots were patches of dandruff and flaky skin, not white hair. So, they were easily remedied.
What has your horse been eating? Do you think he may have something metabolic going on? That can usually manifest itself in the coat, as the others have suggested... Or, they could just be birdcatcher spots.
Thanks for the ideas. I think I will have blood pulled to see if he has anything going on.
He has been turned out with, and eating the same thing as Petey who looks like a shiny copper penny.
He has not been sick, and whenever it rains he makes sure he does not get wet. He is very sybaritic. There is no environmental cause nor health reason for these spots that I know of.
re: Birdcatcher or Bend Or spots: He is 16 years old! Can a horse break out in masses of Birdcatcher spots at his age? I just checked his pedigree and I can't find Birdcatcher in it (although I did not check all the female lines, so he might be in there somewhere.) Plus, I have never seen Birdcatcher spots on a brown horse, only on chestnuts.
But something is happening, that is for sure. Hmmmmmm, I would not put it past George to find a way to get more attention. He is very crafty that way.

We had a chestnut school horse at our barn who some years would get these spots, and then they would disappear as the year went on. They looked just like the ones on your horse. It was a nutritional issue--copper deficiency, I think.

I had a black bay mare with birdcatcher spots. They showed up when she was 8. They were kind of fascinating because they would move and change over time. I thought it was neat. Just ran into a former horse of mine, a super cute chestnut, who is now covered in them in as well. She's 10 this year.

Welcome to the club. Birdcatcher spots, vitaligo, or unknown random spotting. My mare did this. She was Swedish, but 3/4ths TB, and bright chestnut. About four random little white hairs appeared. Over the years they would slowly grow up to about the size of a quarter all over her body, and the skin turned pink underneath. She had white spots in her mane and tail, too. By the time I lost her at 14 she looked like an Appy.
My theory is it seems to be in the TB bloodline. I think it is very cool.
I would agree with a probable copper deficiency. I would get blood drawn. My first thought when I glanced at the pictures was ringworm growing in white, but you said he hadn't had a fungus during the winter, so that's not it then. His whole coat does look dull to me, but it's hard to be sure in pictures.
