This is the first palomino I've ever had. During summer when I got him he was a pretty dark color, now his body is as light as his mane and tail. He got REALLY light colored. Do they all do this? When the winter hair comes off will he be back to the dark?
Most likely he will be darker in the summer. Mine did the same thing (I got her last May). When he sheds his winter coat he should go back to what he was (or something close to it). How old is he? I've heard that they tend to get darker with age, but I've also heard that they are all different and some get lighter from year to year and some get darker. So who knows?
Of course keeping his sun exposure minimized in the summer will keep him darker (mine's not a show horse so I don't care) and you can also try supplementing with paprika or "Gold as the Sun" (I think that's the name) which is mostly paprika, but a lot more expensive. Supposedly that will help them shed out darker. Good Luck!
No worries...I have 2 pals and they both do this. I thought it funny the first year but they've always shed out a nice golden color come spring. Bleach over the summer, almost an off-white/pale yellow in winter.
Example - Dove in summer... (ignore my leaning on her neck please!)
Yeah, I actually posted something on here about how mine has black hairs on her muzzle in the summer, but they are gone in the winter. She lightened up so much in the winter that I noticed that she has a small snip, it wasn't visible under the black hairs in the summer.
We don't have bad Winters here, so he doesn't get as fluffy as some, if he did I would expect him to lighten more then he does, but he doesn't really lighten all the much. Now my first palomino was a pale yellow in the summer, and in the winter it use to bug the crap out of me for people to refer to her as the white horse.
