Spring Rugging: the Rule of Thumb Behind the Routine

Spring is the season where owners need to adjust rug weights according to the daily forecast, not the calendar, because comfort changes with every warm afternoon, cold morning, or unexpected shower. A flexible approach keeps the skin healthy, supports shedding, and prevents the discomfort that comes from over‑rugging during this transitional period.
Of course, you need to adjust your routine according to your conditions, but this is what we do here at Sound Advice. We have two horses on our property who are unrugged. They manage their weight very well over winter, don't suffer from insect allergies and are not in work, so rugs are not necessary.
For the horses that are rugged, here are our rules of thumb:
Spring Rugging
No rug for days over 18°C
For days above 18 degrees, a winter rug traps too much heat. The horse’s skin begins producing more oil as the coat loosens, and a heavy rug creates a warm, humid microclimate that encourages scurf, greasy patches, and even early rainrot. We leave the horse unrugged during warm days which lets the skin breathe and prevents moisture buildup.
Winter rug for nights under 10°C
Nights under 10 degrees can feel sharp, especially for horses with thinner coats, are older, or hold less condition. A winter rug at night protects them from cold snaps without interfering with daytime shedding. This is the balance point where comfort meets biology.
Rainsheet for nights over 10°C - Using a Rainsheet as the Spring Transition Rug
A rainsheet is the perfect bridge between the winter rug and the summer cotton. It gives your horse protection without trapping heat, and it’s especially useful during those unpredictable spring weeks where the weather can’t decide what it’s doing. Once nights are consistently over 10°C, most horses no longer need the insulation of a winter rug, but they still benefit from a lightweight barrier against wind and rain. A rainsheet keeps the coat dry without creating the warm, humid microclimate that encourages skin conditions. It’s also the rug we reach for on rainy days when the winter rug would be too heavy and the cotton too porous.
No rug during the day once shedding begins
This is one of our most important spring practices. When shedding starts, the horse needs friction and airflow to help the winter coat release. Rolling is the horse’s natural way of “removing their own rug.” If you keep a rug on during shedding season, you flatten the coat, trap humidity, and slow the skin’s ability to clear old hair and oils. Unrugged days let the horse use movement, rolling, and sunlight to transition the coat smoothly.
Cotton or mesh rugs after the winter coat is shed
Once the winter coat has fully released and the spring coat is in, the skin becomes more sensitive to insects. This is when cotton or mesh rugs make sense. They protect the skin without trapping heat, and they allow airflow across the body.
For horses that get itchy during the coat transition, this spray is very useful.
Storing Your Winter Rugs
Once your horse is consistently comfortable in lighter layers, it’s time to retire the winter rug for the season. The way you store it now determines how long it lasts and whether you’re dealing with mould, spiders, or chewed straps next autumn.
If you don't have a dedicated rug washing machine at home, many laundromats offer a machine specifically for pet bedding.
After the rug is washed, hang it in the sun until every seam is dry. Even a small patch of dampness can turn into mould in storage, and mould weakens stitching and fabric. If it was only brushed off, still give it a day of air before packing it away.
Check for small tears, broken hardware or loose stitching. Repairs are easier now than in the first week of winter when you suddenly need the rug again.
When it’s fully dry, you have two good storage options. The first is the zip‑up bag it came in. Those bags are designed to keep dust, moisture, and insects out, and they’re ideal if you have a clean, dry shelf or tack room. The second option is a sealable storage tub. This is especially useful if your shed attracts spiders, wasps, or rodents. A solid tub protects the rug from chewed straps, nesting insects, and the kind of damage that only shows up when you pull it out on the first cold day of autumn.
Label the tub if you have multiple rugs. (we store them by sizes). A little organisation now saves frustration later.
You may be lucky enough to have a rug wash and repair service in your area who will return a whistle-clean, tear-free rug in a vacuum-sealed bag - just like new. This is money well spent, and your future self will thank you!
