Should I Rug My Horse? The Cardigan Advice
So you are stuck, the weather is warm one minute and cold the next, you are not there to take the rug on or off. What to do?
Now you may be wondering where the cardigan comes in, I am not going to suggest that you knit one for him, but think about how horrible it feels when you are too hot and can't take your coat off. Horses are the same, even if the weather is awful their heat comes from their food and they are meant to regulate their coats to be comfortable.
Don't know if yours did, but my mother was always saying to me: Where's your cardigan, why aren't you wearing it? Well I wasn't cold but SHE WAS! This is your trap, be stingy with rugging, it feels horrible to be too hot, just make sure they have plenty of hay or grass if allowed to generate their own perfect heat.
They won't die if they have to shiver a bit (this generates heat) till you get back but spending hours being too hot is horrible.
If you want to see, the sort of temperature range a normal, healthy horse can cope with.
🐴 The key idea: horses are built for the cold
A healthy horse with a good winter coat is surprisingly tough. In fact, they’re usually more comfortable in the cold than heat.
🌡️ Rough temperature guide (UK conditions)
-
10°C and above
→ Most horses are perfectly comfortable without a rug
→ Rugging here can actually make them too warm -
5°C to 10°C
→ Still fine unrugged for hardy/native types with full coats
→ Older, clipped, or finer horses might need a light rug, especially if wet/windy -
0°C to 5°C
→ Most horses still okay without a rug if dry, sheltered, and unclipped
→ Clipped horses usually need a light to medium rug -
Below 0°C
→ Most horses will still be fine without a rug as above.
→ Clipped or older horses often need medium to heavy rugging
🌧️ The real game-changer in the UK: wet + wind
In places like the UK, rain and wind matter more than temperature.
- A horse can be fine at -2°C and dry
- But uncomfortable at +6°C with rain and wind
If they lose the insulating effect of their coat (flattened by rain), they chill much faster.
🧠 Things that matter more than the thermometer
- Clipped vs unclipped (clipped = needs rug sooner)
- Breed/type (native ponies vs finer TB types)
- Age (older horses struggle more with cold)
- Body condition (thin horses feel cold sooner)
- Access to shelter they prefer thick hedges
- Whether they can move freely to choose where to stand
👀 Best rule: use your hands, not just the forecast
Put your hand under the rug:
- Warm and dry → perfect
- Sweaty → too much rug
- Cold skin (not just cool coat) → consider rugging
- Make sure they have plenty to eat, well soaked hay if needed.
