I am in the group that if my black horse wants to enjoy the sun it is her choice as she can go in and out when ever she wants. I also show and I believe in letting nature take it's course. Just so they are healthy and happy is my biggest concern
I stall mine during the day in the summer, not because she fades, but because she's a bald face horse and her pink skin sunburns. I put sunscreen on and let her out the last couple of hours of the day, then put her back in her stall at daylight.
I out my horses out early in the morning (around 4am) and then they will get let in around 10-11am and then get let out around 5 for a couple of more hours. They hate being out in the heat of the day, but maybe that is because they are spoiled and have fans hung in their stalls in the summer. :)
My horse's LOVE coming inside during the summer days. It's like a stampede come 10:30am when I put them in. They get grained, hay and are fly-free. My mare has a white face as well and she will burn if she's out too much during the summer days. My horse's are spoiled.
there's a serious problem with the mentality that a horse needs to be locked up and not exposed to sunlight to win a piece of colored cloth. Both in the show er and the organization that encourages such behavior by its scoring methods.
They are horses not vampires.
I'll never understand why some things are considered acceptable in showing and other things aren't. I don't tend to understand silly human convention in general, but when it gets applied to animals I understand it even less. I think they're not only NOT vampires, but they're living creatures, so I don't see why they have to be made to look like a freshly unpackaged doll.
My black horses are outside year round and don't fade. I was told that a true black horse does not fade, and I do believe that now, since my black horses do not fade. It gets up to 110 here in the summer and we get little rain.
