When she was first born, it was a darkish spot on her coat. As she grew, it became lighter. Usually, it's not so apparent in the summer, but this year I'm still waiting for it to shed out. She will be 2 years old this month.
It will be mostly covered by the saddle when ridden based on where it is. But... I wonder... do you think this would affect asking price of a horse? or would it not be an issue if the horse is well-suited for its discipline?
I have no idea what causes it, but I have a solid bay mare with a small patch like that on her neck. It never changes color or size & is there year round. Her only other "color" is a dime size white spot on her heel. She's had 2 fillies by totally solid bay stallions. One is chestnut with a star, snip & a white spot on a front. The other is a bay with a large star & short, irregualr hind. Pics attached. First 2 are the 2007 filly, third is her 06 filly, last 2 are her.
I don't think it will affect your filly's asking price since you really won't see it under tack. Or rather, it should not affect her price.
Another person here who doesn't know what it is but knows a horse with it. One of my trainer's mares is a solid chestnut, with a roan patch on one of her hocks. It actually covers a fairly large area, but it's not a very dense roaning - pretty sparse so doesn't look like a concentrated white spot. It seems to be getting a little more apparent as she ages, but minimally.
And no, I don't think that should affect the value of your horse in any way.
My chestnut QH has one on his neck! He also has tons of bend or spots. He has a star, stripe, snip and 2 hind socks. Tons of people ask me if he is a paint because of it but since there is not white hair under it he's not.
We have a lot of these patches/spots/markings on the farm through a particular combination of bloodlines. I'll have to shoot some new photos but one mare has a series of vertical roan stripes on her flanks, a gelding (who is chestnut) has a liver chestnut front leg and multiple roan patches & Ben D'Or spots all over the place, a couple of the youngsters have Birdcatcher spot (one has them in both armpits!) and then there is the smattering of random roan spots and Ben D'Or splotches.
It has gotten more prominent as she has gotten older. I don't think I've ever seen anything like this before on a warmblood. It could be that I didn't notice it as some of them are not in such prominent places. But it's interesting nonetheless. She also has the "silver" tail, or flaxen in her tail, and I've wondered if that's related to the roan spot. And I've recently noticed a patch of roaning on one of her back pasterns.
Thank you for those of you who provided pictures. Nice horses, by the way. And for providing bloodlines as well, because I was wondering if this type of this thing runs in certain lines. My filly is by Escapade out of a Prinz Gaylord mare. And the PG mare's mother was a TB by Bunny Dancer out of a Khalea mare. She is a gray, so I wondered if it had anything to do with the gray gene, although I wouldn't think so because gray is expressed all over, not just in one spot.
Here you go - 2 of the 2007/2008's have funky spots...
The first 2 on the left are the 'normal' ticking that lots of the horses bred here seem to have. His are limited to just his barrel.
The 2 on the right are not(!) camera glare but Puck's large 'clump' of roan hairs...Please excuse his hirsute belly. It is always the last one on the farm to shed - very odd but part of what makes Puck Puck!
Another chestnut mare with the roan in stripes on her right flank while it is 'regular' distribution of roan hairs on her left flank. The right side of her face is getting more and more white hairs each year...
