How can you stop a horse from rubbing its tail and making parts of it bald?

There are several reasons why a horse might rub its tail, causing parts of it to become bald. Here are some common causes and steps you can take to try to stop the behavior:

Itching: If your horse has a skin condition or insect bites that are causing itching, it may rub its tail to try to relieve the discomfort. Treat any underlying skin conditions and take steps to control insects in your horse's environment.

Stress or boredom: Horses may rub their tails out of boredom or as a way to relieve stress. Provide your horse with adequate exercise, enrichment activities, and social interaction to keep it mentally and physically stimulated.

Improper tack or fit: A poorly fitting saddle or harness can cause discomfort and lead to your horse rubbing its tail. Ensure that your horse's tack fits correctly and there are no pressure points.

Environmental factors: Sometimes, horses rub their tails on objects in their environment, such as trees or fences. Remove any objects that your horse might be rubbing its tail on.

Skin irritants: Certain substances, such as fly repellents or grooming products, can irritate a horse's skin and cause itching. Experiment with different products until you find one that doesn't irritate your horse's skin.

Infections or allergies: Horses may rub their tails as a result of bacterial or fungal infections or in response to allergic reactions. If you suspect an infection or allergy, consult with your veterinarian.

If you have tried to address the common causes listed above and your horse is still rubbing its tail, it's best to consult with a veterinarian to investigate further and rule out any underlying medical conditions. They can properly diagnose the issue and recommend the best course of treatment.
