Belle doesn't do sweaty unless it gets really warm, she didn't even get sweaty when it was touching 30 in the summer, but then she hadn't got her winter woollies.
It was 2 degrees here this morning when we hacked out, definitely not sweating weather for either of us!
Ben is getting a really thick coat and is sweating under his long mane. All the other horses who are stabled at night are being rugged up, but he is really hot just standing still. I have always clipped him throughout the winter months so it will be interesting to see how thick his coat gets.
