Rain rot, also known as rain scald is a contagious bacterial skin disease that is commonly seen in horses, goats, sheep, cattle, rabbits and other furry animals. It may look similar to fungal disease, but don’t get confused, the former is distinguished by bare spots on the skin. An obvious symptom is a crusty scab that envelopes the infected area. Eventually, as it dries, it creates a clump and peels off, thus leaves an unsightly bald mark on the parts of the neck, the head and the back. However, there is to need to worry about these things so long as you know the best treatment for rain rot. It also helps to know how it can be prevented.

Important Ways to Prevent Rain Rot

Indeed, it is always better to prevent it in advance than to cure it. There are some simple routines you can do. There are also necessary things you should provide in order to avoid rain rot and other possible infections among horses.


According to study, mutual and regular grooming among horses demonstrates companionship; therefore, it is safe to say that they enjoy some ticklish brushing. Nevertheless, you should be aware which parts are sensitive to touch. Health-wise, it helps maintain a fine coat and skin. With daily grooming, you should also spot possible health problems before they worsen.

Additionally, sharing grooming tools with other horses may not be a very good idea since bacteria can possibly spread out. Buying some extra is quite costly but for the benefit of your animals, this shouldn’t be a big issue. Sterilizing the tools is another good (cheap) option if you are really out of budget.

Providing Shelter

When rainy season comes, providing the animals with a comfortable clean dry place would help them protect from various diseases. Rain rot is most expected when the animals are left out in the rain for a prolonged period of time. For farm animals, make sure you set up some lean-tos for them to shelter. Your barn should also be well maintained to ensure good health and safety. Furthermore, providing some waterproof blankets should keep them dry and away from containing rain rot.

Using Insect Repellants

Along with the rain are the insects. These pests sure contribute to infecting your farm animals with rain rot. With a wet environment and insect bites, they become more prone to carrying bacteria which leads to complications and other health issues.

A good solution would be using insect repellant. It does not only prevent your farm animals from having rain rot. It also safeguards them from a more fatal illness. You may feel that applying repellant to your horses’ skin is a lot of work. But you should remember that trying to cure something worst later could be more tiring and frustrating than it.
