Scabs on Horse Fetlocks: Causes and Adapted Natural Treatments
Why do scabs appear on white markings (balzanes)?
White markings (balzanes), those characteristic white marks on horses' legs, are particularly vulnerable to skin problems. The depigmented skin in these areas is thinner, more sensitive, and less resistant to external aggressions. To better understand skin distress in general, consult our guide on skin distress in horses.
The different causes of scabs on white markings
1. Mud fever (pastern dermatitis)
Mud fever is the most common cause. It results from prolonged exposure to moisture and mud.
Symptoms: Thick yellowish or greenish scabs, red and painful skin under the scabs, possible oozing, leg swelling, lameness in severe cases, unpleasant odor.
2. Allergies and contact dermatitis
White markings can develop allergic reactions to various allergens: insect bites, pollen, irritating grooming products, bedding, or photosensitization (sun reaction on white skin).
Symptoms: Intense itching, redness, scabs formed by scratching, thickened skin in chronic cases, hair loss.
3. Fungal infections (dermatophytosis, ringworm)
Fungi colonize the skin of white markings, especially in humid environments. Symptoms: Circular lesions with scabs, patchy hair loss, dry and flaky scabs, little or no itching. Contagious to other horses and sometimes humans.
4. External parasites
Chorioptes (pastern mites), lice, and ticks can cause crusty lesions. Symptoms: Significant itching, especially at night, scabs from scratching, skin thickening, restlessness, stomping. These parasites can also cause weeping sores due to chronic inflammation.
5. Infected wounds and sores
A poorly treated wound can form significant scabs with purulent discharge, local heat, pain, and delayed healing.
Golden rule: NEVER pick at scabs
⚠️ WARNING: Picking at scabs causes bleeding, creates new entry points for infection, aggravates inflammation, delays healing, and can create permanent scars.
The right approach: Allow scabs to soften naturally with appropriate care. If cleaning is necessary, first soften with warm water and remove very gently, without forcing.
Natural treatments adapted to the cause
For mud fever and allergies: OZONE MUD CARE
Specially formulated to protect and treat moisture-related conditions: creates a protective barrier, antibacterial action, soothes inflammation and itching, promotes drying and healing.
Protocol: Clean with warm water without scratching, pat dry, apply OZONE MUD CARE generously 1-2 times/day. For prevention: apply before turnout in wet weather.
For fungal infections, wounds, and parasites: OZONE INTENSIVE CARE
Concentrated formulation to treat deep infections, wounds, and parasitic infestations: powerful antifungal action, broad-spectrum antibacterial, antiparasitic, stimulates healing, oxygenates tissues, non-irritating.
Protocol: Clean with warm water, allow scabs to soften without scratching, dry, apply OZONE INTENSIVE CARE directly to lesions twice a day until complete healing. For parasites: also treat adjacent areas. Consult our complete wound care protocol.
Summary table
| Type of problem | Recommended product | Frequency |
|---|---|---|
| Mud fever | OZONE MUD CARE | 1-2 times/day + prevention |
| Allergies and dermatitis | OZONE MUD CARE | 1-2 times/day |
| Fungal infections | OZONE INTENSIVE CARE | 2 times/day |
| Wounds/sores | OZONE INTENSIVE CARE | 2 times/day |
| Parasites (mange, lice) | OZONE INTENSIVE CARE | 2 times/day + adjacent areas |
Essential complementary measures
- Environment: clean stall with absorbent bedding, well-drained paddock, avoid mud, stable the horse in wet weather
- Hygiene: always dry legs after washing, disinfect equipment, isolate if contagious (ringworm, mange)
- Parasites: regular deworming, insect repellents, treat all horses in contact
- Nutrition: balanced diet rich in vitamins A, E, zinc, biotin, and omega-3
Healing time
- Mild mud fever: 7-14 days
- Severe mud fever: 3-6 weeks
- Allergies: rapid improvement (3-7 days) if the allergen is eliminated
- Fungal infections: 2-4 weeks
- Pastern mange: 3-6 weeks with rigorous treatment
- Wounds: 10-21 days depending on depth
When to consult a veterinarian?
Consult quickly in case of extensive or worsening lesions, severe lameness, significant leg swelling, fever, no improvement after 7-10 days, suspicion of ringworm, or frequent recurrences.
Prevention of scabs on white markings
- Preventative protection: apply OZONE MUD CARE before exposure to moisture
- Rigorous hygiene: daily cleaning and drying of legs
- Monitoring: daily inspection of white markings, rapid intervention at the first signs
- Allergy management: insect repellents, avoid known allergens
Conclusion
Scabs on white markings are a common problem but manageable with an adapted approach. Identifying the cause is essential: OZONE MUD CARE for mud fever and allergies, OZONE INTENSIVE CARE for fungal infections, wounds, and parasites.
Remember: never pick at scabs. With natural ozone care and rigorous environmental management, the sensitive skin of white markings will quickly regain its health!
