When to blanket your horse
The decision to blanket a horse depends on several factors: body condition, age, health, coat thickness, and whether the horse is clipped. A healthy horse with a thick winter coat and good body condition can tolerate temperatures well below freezing without a blanket, as long as it has shelter from wind and rain. Typically, a horse with a natural winter coat can handle temperatures from about 20°F to 40°F without a blanket. Once the wind chill drops below 20°F, or if the horse is wet, elderly, thin, or clipped, a blanket becomes beneficial.
A good rule: if you need a heavy winter coat, your horse might too , but check its body language. Shivering is a clear sign it’s too cold. Conversely, sweating under a blanket means it’s too warm.
Choosing the right blanket weight
Blankets come in three main weights: light (50-100g fill), medium (150-250g), and heavy (300-400g+). The fill refers to the amount of insulation. For mild winter days (30-45°F), a light sheet or no blanket may suffice. For cold spells (10-30°F), a medium weight is typical. For extreme cold (below 10°F) or clipped horses, a heavy weight is needed. Always layer lighter blankets rather than using one overly heavy blanket, as layering traps warm air and allows adjustment.
Consider the denier (D) of the outer shell: 600D to 1200D or higher. Higher denier is more durable for turnout, while lower denier is lighter for stable use. Waterproof and breathable materials are crucial for turnout to keep the horse dry while allowing moisture to escape.
Proper fitting and layering
A well-fitted blanket should sit a few inches in front of the withers, extend to the tail, and fasten securely at the chest without rubbing. The leg straps should be crossed to prevent shifting. Check for rubs at the shoulders and withers daily. When layering, put a lightweight sheet under a medium or heavy blanket, ensuring the top blanket is adequately sized to accommodate both. Avoid using a turnout blanket over a stable blanket unless both are designed for layering, as this can cause sweating.
Always dry the horse thoroughly before blanketing. Applying a blanket over a wet or damp horse can chill it further as moisture evaporates. In wet snow or rain, a waterproof turnout blanket is essential to keep the coat dry. In dry cold, a breathable, water-resistant blanket is fine.
Monitoring and adjusting
Check your horse at least twice daily. Feel under the blanket at the shoulders and behind the ears. The horse should be warm and dry, not sweaty. If it’s sweating, remove or lighten the blanket. If it’s shivering, add a layer. Also check for any rubs, pressure sores, or blanket slippage. Remove the blanket every few days to inspect the coat and skin, and give the horse a chance to roll and groom.
Consider the environment: if the horse has access to a run-in shed or barn, it may need less blanketing than one constantly exposed to wind and precipitation. Horses acclimate to cold over weeks, so sudden cold snaps may warrant a blanket even for unclipped horses.
Special cases: clipped, aged, or sick horses
Clipped horses lose their natural insulation and require blanketing once temperatures drop below 50-60°F. Use a medium to heavy blanket depending on the clip pattern and temperature. Older horses may have difficulty regulating temperature or have arthritis, so they often benefit from a blanket even at milder temperatures. Horses with Cushing’s disease or other chronic conditions may have a heavier coat but still be vulnerable to temperature extremes , consult your vet for guidance.
Always remove the blanket periodically to assess the horse’s condition. Never leave a blanket on for weeks without checks. If you notice any health concerns such as abnormal sweating, shivering, weight loss, or coat changes, contact your veterinarian.
By following these guidelines, you can keep your horse comfortable and healthy throughout the winter.
Key Takeaway
Blanket your horse based on its individual needs, weather conditions, and body condition, adjusting layers to prevent overheating or chilling.
