Okay, so I have an 18 yr old Arab gelding who up until now has been doing pretty well in the weather I've been having (rain, wind, storms ect). Where I am it's the middle of winter. When I went out to feed him this afternoon I found him shivering so I chucked a medium rug on him. (I bought it to keep the rain off, he's a litttle prone to rainscald). It was about 13 degrees Celsius. I'm pretty inexperienced when it comes to rugging so I'm asking for advice, should I keep him rugged in the medium rug I have? Should I get a heavier one as it gets colder? Should I just leave him?
He's a live out horse, I don't have access to shelter, and he has 3 cows as paddock buddies.
Any advice would be appreciated thanks :)
