Your horse's coat might be smarter than you think!

Because your horse was designed to spend his days roaming outside, he is naturally equipped with tools to keep himself warm when the temperatures start cooling down. Here, we’ll take a look at what your horse does to stay warm, and why that might not always be enough.

In response to the fading sunlight, your horse’s body starts producing his winter coat as soon as the days start getting shorter. He begins to grow his longer, thicker winter coat in July, shedding the shorter, thinner summer coat in October. That winter coat has longer and coarser hairs than his summer coat, and he uses them to keep himself warm by fluffing them up to trap heat. The individual hairs stand up rather than lying flat against the skin, which traps warm air close to his body and insulates him from the cold.

Along with using this thick hair coat to stay warm from the outside, your horse also uses calories to keep himself warm from the inside. His body ferments roughage in the hindgut, which creates heat that helps maintain his core temperature, which is why many horse owners feed more hay in the winter.

However, even your horse’s full winter coat and normal calorie intake may not be enough to keep him warm all winter, depending on his body’s lower critical temperature or LCT. Your horse’s lower critical temperature is the lowest temperature at which he can maintain his core body temperature without using additional energy. Once the temperature outside gets below that lower critical temperature, his hair coat and normal calorie intake alone aren’t enough to keep him warm.

The lower critical temperature of an individual horse will depend on the temperatures that he’s accustomed to, the amount of body insulation he has (such as the length of his hair coat and the amount of body fat), and whether he lives inside or outside. That’s why even horses with a full winter coat can sometimes benefit from a blanket!

What to Wear and When

Sheet or blanket? Stable or turnout? If your horse is going to be outside, you’ll want to put on a turnout, whereas you can choose a stable if he’s only going to be in the barn. Depending on the temperature, you’ll choose a sheet if it’s warmer outside and a blanket if it’s colder, but just like Goldilocks, your horse wants his blanket to be just right. Deciding how much to bundle your horse up can be tough

Just like it does for us humans, 40 degrees will feel different to a Florida horse in October than it will to a horse in Chicago in February, so you’ll need to dress your horse differently depending on the temperatures he’s used to.

In addition, the temperature outside isn’t the only factor to consider when you’re choosing the right blanket for the weather. Other factors, like your horse’s living environment and whether or not he’s clipped should also be taken into account.
