We seem to always have a rainy and windy winter, so I was wondering about blanketing. My horses sometimes run around outside while it is raining, instead of staying in their barn, so their hair is always wet! I am afraid that since their hair is laying flat that they are going to become chilled. I do not clip them and they are brushed everyday so it would be taken off and they would be checked. Should I get a waterproof/breathable blanket? Or do you think they will be ok?
