Horse dermatitis: How to treat summer dermatitis?

Introduction: Act quickly at the first signs

Among essential horse care, prompt treatment of horse dermatitis is crucial. The beginning of the season, between late winter and early spring, is a critical period when many horses develop the first symptoms of sweet itch.

Early intervention can make all the difference between a simple, temporary irritation and chronic sweet itch that will bother your horse throughout the warm season. Discover in this article how to understand and effectively treat this inflammatory skin condition. For a comprehensive overview of this condition, consult our comprehensive guide to equine sweet itch.

What is equine sweet itch?

Equine sweet itch, also known as recurrent equine dermatitis (RED), is an inflammatory skin disease that affects many horses. Contrary to what one might think, it is not solely caused by insect bites.

Definition and manifestations

The word "dermatitis" simply means inflammation of the skin. In the case of sweet itch, this inflammation generally manifests as:

  • Intense redness on affected areas
  • Crusts and skin lesions
  • Intense itching (pruritus)
  • Hair and mane loss due to scratching
  • Open wounds caused by repeated rubbing

An often unrecognized origin: decreased immunity

Sweet itch is primarily caused by an inflammatory reaction linked to a decrease in immunity that often appears in late winter or early spring, even before the massive arrival of biting insects.

This weakened immunity makes the body fragile and triggers a cascade of inflammatory reactions that then make the horse hypersensitive to bites from midges (culicoides) and other environmental allergens.

The physiological mechanism of pruritus: understanding itching

To effectively treat dermatitis, it is essential to understand the mechanism that causes this unbearable itching for the horse.

The central role of histamine

Physiologically, pruritus (itching) is triggered by the release of histamine, a substance produced by the immune system in response to irritation or allergy.

The inflammatory cascade

Histamine causes a series of chain reactions:

  1. Local vasodilation: Increased blood flow to the affected area, causing redness and warmth
  2. Increased vascular permeability: Blood vessels become more permeable, allowing immune cells to enter affected tissues, which creates edema
  3. Stimulation of nerve endings: Histamine activates nerve receptors in the skin, causing intense itching

The vicious circle of dermatitis

Once this process is initiated, a vicious circle sets in. To better understand the different forms of skin irritations in horses and their mechanisms, consult our comprehensive guide on the subject.

  • Itching makes the horse scratch
  • Scratching damages the skin barrier
  • Weakened skin attracts more insects
  • Insect bites worsen inflammation
  • Inflammation increases itching

It is therefore necessary to quickly implement a protocol that stops this spiral. Especially since weakened skin will attract insects and bites will significantly worsen the situation.

Why is immunity at its lowest at the end of winter?

Several factors can explain why a horse's immunity can be weakened in late winter and early spring.

1. Lack of sunlight and exercise

Winter can be a difficult period for the immune system due to:

  • Lack of sunlight which reduces vitamin D production, essential for proper immune function
  • Often reduced physical exercise during cold and wet months
  • A global decrease in activity that affects general health and therefore immunity

2. Climatic stress

Cold temperatures and changing weather conditions can weaken the body:

  • Significant temperature variations
  • Constant humidity and mud
  • Wind and rain that stress the body's defenses

These conditions make the horse more susceptible to imbalances and inflammatory reactions.

3. Winter nutritional deficiencies

Less rich and varied diet during winter can lead to nutritional deficiencies that directly affect immunity:

  • Variable quality hay
  • Absence of fresh grass rich in nutrients
  • Decreased intake of natural vitamins and minerals

4. Abrupt dietary transition in spring

When equids are put back to pasture and fed on grass rich in protein and nitrogen, the body must quickly adapt to these significant changes.

But its winter weakening can lead to:

  • Metabolic adaptation difficulties
  • Inflammatory reactions
  • An imbalance of the intestinal flora
  • Liver overload

Treatment protocol: a holistic internal and external approach

It is essential to treat both the internal and external body in cases of dermatitis, as itching is caused by internal factors (immunity, metabolism) and external factors (skin inflammation, bites).

Step 1: Strengthen immunity and detoxify (internal treatment)

The first thing to do is to boost immunity and cleanse your horse's liver.

Why detoxify the liver?

The liver plays a central role in:

  • Elimination of toxins
  • Regulation of inflammation
  • Metabolism of nutrients
  • Support of the immune system

An overloaded liver cannot perform these functions properly, which aggravates inflammatory reactions.

Available solutions

Several dietary supplements are available on the market for:

  • Support liver function (milk thistle, desmodium, artichoke)
  • Strengthen immunity (echinacea, spirulina, vitamins C and E)
  • Regulate inflammation (omega-3, turmeric)
  • Rebalance intestinal flora (probiotics, prebiotics)

Step 2: Rapid local soothing (external treatment)

In parallel with internal treatment, it is crucial to intervene quickly on the affected areas to stop the vicious cycle of itching.

OZONE SKIN CARE: the emergency anti-itch treatment

OZONE SKIN CARE is particularly effective for the rapid management of sweet itch. Discover in detail how OZONE SKIN CARE acts against sweet itch and why it stands out as the natural reference solution.

Immediate relief
  • Instantly soothes itching
  • Calms the horse and reduces its stress
  • Stops the compulsive need to scratch
Anti-inflammatory action of ozone

The action of ozone helps to:

  • Limit inflammation: Reduces the production of histamine and inflammatory mediators
  • Reduce redness and edema: Vasoconstrictor action that calms the local reaction
  • Soothe nerve endings: Reduces the sensation of itching
Activation of healing

Ozone also stimulates:

  • Cell regeneration
  • Collagen production
  • Repair of the skin barrier
  • Healing of existing lesions
Antimicrobial protection

OZONE SKIN CARE also protects against:

  • Secondary bacterial infections
  • Fungal infections
  • Colonization by opportunistic pathogens

Application method

  1. Gently clean affected areas with lukewarm water
  2. Pat dry (do not rub)
  3. Apply OZONE SKIN CARE generously to all affected areas
  4. Gently massage to penetrate
  5. Repeat 1 to 2 times a day until improvement
  6. Continue as a preventative 2-3 times a week

If the lesions are oozing or purulent, apply OZONE INTENSIVE CARE as a first step until healing begins.
