A healthy, shiny coat is a sign of your horse’s well-being. But if suddenly more hair falls out than usual or bald spots appear, many horse owners wonder: Is this still normal, or a warning sign? The causes can be harmless but may also indicate serious skin problems.

Natural causes of hair loss

Hair loss in horses is often a completely normal process.

• Coat shedding: In spring and autumn, horses shed their coat to adjust to the seasons. During this time, larger amounts of hair can fall out temporarily.

• Mechanical friction: Saddles, blankets, or halters can rub off the coat in certain areas—especially if they don’t fit properly.

• Play or social contact: Roughhousing with other horses can also leave small bald patches.

When you should be alert

If hair loss is unusually severe, bald spots get bigger, or additional symptoms like itching, dandruff, redness, or weeping skin occur, you should take a closer look. Common causes include:

• Parasites such as mites, lice, or lice eggs

• Fungal infections (e.g., ringworm)

• Bacterial skin infections

• Allergies to insects, feed, or bedding

• Skin injuries caused by scratching or rubbing

Did you know? Your horse’s skin barrier is crucial for a healthy coat. If this protective layer is weakened—due to moisture, parasites, or irritants—the skin can become irritated. This often leads to increased itching, more rubbing, and eventually bald spots.

First steps with hair loss

• Observe carefully: Note when and where the hair loss starts and if it changes.

• Adjust care: Thoroughly clean equipment and ensure a good fit to avoid friction.

• Soothe the skin: Use gentle, skin-friendly care products that support the skin barrier.

• Veterinary consultation: For unclear or persistent problems, always consult a veterinarian.
