Cold-Weather Tips for Horse Owners from New Bolton

February 2016

Winter temperatures are finally here, and horse owners need to prepare for cold weather. Liz Arbittier, VMD, staff veterinarian in the Equine Field Service at Penn Vetís New Bolton Center, offers six important tips to keep horses healthy and safe during the icy days of winter.

  1. Provide adequate shelter: Horses can do fine living outside through the winter. As long as they are metabolically healthy, receive enough calories, develop a nice winter hair coat, and have appropriate shelter, they can happily ride out a bad winter that has humans groaning. Many horses donít need to be blanketed, although waterproof/breathable blankets can help protect against driving wind and rain. Cold temperatures alone donít generally make horses uncomfortable, but wind and moisture can be difficult for them to tolerate, so they must be able to escape the elements. The best solution is a structural shelter that is big enough to allow all of the horses in that field to safely get out of the weather. One horse with a very dominant personality that wonít allow more submissive types into the shed may be a problem, so owners need to evaluate the personalities in the herd to ensure that this doesnít happen.
  2. Provide adequate calories: The phrase ďbulking up for winterĒ is no joke! Horses expend significantly more calories keeping warm in the winter than they do any other time of year. High-quality hay should be the staple of any winter diet, especially for horses that are turned out a lot. They should have dry, fresh hay available at all times to keep their caloric losses less than their gains. Older horses or horses with significant dental disease that cannot eat hay productively need to receive calories more frequently in a form that they can use, such as senior feeds.
  3. Water not ice: One of the major causes for colic in the winter is an impaction caused by inadequate water intake. Technology has provided us with excellent solutions to that problem: heated water tubs and non-freezing automatic watering systems. If horses are outside, it is well worth the expense to run electricity to the fields for these devices to ensure a constant source of fresh water. Providing water is a relatively easy way to prevent a common winter colic that could end tragically.
  4. Blanket consistently and check frequently: Blanketing for horses that live outside can be necessary to keep them warm, dry, and happy. However, things can lurk under a blanket that can create a problem if not detected early. Bacterial skin disease, commonly known as rainrot, can occur if a horse with a thick hair coat is repeatedly sweating and then drying under a blanket. Changes in body condition, such as a horse that is losing weight rapidly, can also be missed if the blanket isnít removed frequently to check. Itís a good idea to take note of any new lumps and bumps that may not be seen with the blanket on.
  5. Be smart about clipping: Horses have a thick winter hair coat designed to protect them. Many people who ride throughout the winter find it helpful to clip their horses to remove heavy hair that slows drying time after a ride. It is fine to turn out appropriately blanketed, clipped horses in the winter weather. However, owners should be very cautious about clipping horses that live outside through the winter because they will then need to be very diligent about blanketing as temperatures fluctuate. It isnít fair to a horse to remove his winter woolies and then not blanket him well enough. Owners who have clipped their horses entirely, including the head and ears, need to be diligent about keeping them inside during excessively cold temperatures, as frostbite can occur.
  6. Pay attention to footing: Horses do just fine in any amount of snow, but ice is another story. Be very cautious about ice on surfaces where the horses walk, either to get to turnout or within their turnout. Fractured bones or down horses can be a sad consequence of dicey footing. Keep large amounts of snow/ice melt handy for when ice develops. (But donít forget to watch out for your cats and dogs that might not tolerate rock salt on their pads!) Horses that are shod and live in snowy regions could benefit from a farrier applying a special pad to prevent the balling-up of snow inside their shoes. These snowballs can create 4-inch stilettos that are very unstable and can lead to injury. With ice and snow, make sure that your farrier and veterinarian have good access to your horses: plowing/salting driveways is very important to providing care, especially in an emergency situation.
