For the first time I've found myself with a horse who does not need industrial quantities of hard feed to get through the winter without looking like a hat rack. In fact after a winter of just low energy chaff and a balancer he is still a little plumper than I'd like. He hasn't had a rug on for at least the last month, other than a rain sheet if it's been wet.
Now the temperature is due to go down to about -2 I'm wondering whether he'd cope without a rug on, and it it might even be good for him to shiver off some weight. I will feel a bit mean though if I do leave him naked. I'd be interested to know what other people do.
