Rain Rot

What is dermatophilosis in horses?

Dermatophilosis is a skin infection caused by the proliferation of an opportunistic bacterium. It develops when the skin remains constantly moist, macerated, or weakened, which explains why horses living outdoors or exposed to repeated rain are particularly affected.

The most commonly affected areas are:

• the back

• the croup

• the flanks

• the neck

• the head

• the topline in general

The disease manifests as small crusts and tufts of hair that detach easily, sometimes accompanied by sensitivity or pain. If left untreated, the lesions can spread and become uncomfortable for the horse, especially under the saddle.

Contrary to common belief, dermatophilosis is not caused solely by rain: it is multifactorial. Dry or irritated skin, damage caused by equipment, or insect bites can also promote its development. A weakened immune system or a poorly ventilated environment may further aggravate the condition.

How to recognize dermatophilosis ?

The most common symptoms include:

• small, hard crusts grouped in patches

• hair falling out in tufts

• sensitive or painful skin

• a rough texture to the touch

• areas that are wet or oozing

• difficulty brushing or saddling the horse

When the crusts detach, they may leave the skin pink, sensitive, or slightly irritated. In advanced cases, the horse may show discomfort, refuse to be touched, or experience reduced performance due to irritation.

How to naturally relieve dermatophilosis ?

Treatment of dermatophilosis relies on two essential actions: cleansing the skin and protecting the affected area from moisture and bacteria. Natural products help soothe the skin without irritation while supporting gentle healing.

The affected area should be kept as dry as possible, avoiding aggressive brushing. Local clipping may be recommended for horses with long or thick coats. The goal is to limit moisture and allow treatments to work more effectively.

Natural care solutions from the shop Arbalou.

The Boutique de l’Arbalou, provided by Arbalou Care, offers two products specifically designed to support horses affected by dermatophilosis: Arbalou Herbal Beauty and Arbalou herbal Spray.

Arbalou Herbal Beauty a purifying and cleansing care

Arbalou Herbal Beauty is a 100% natural product designed to purify the skin, cleanse lesions, and help crusts detach naturally. Rich in plant extracts known for their antiseptic, soothing, and regenerating properties, it works directly on affected areas to help the skin regain balance.

This treatment is particularly effective for:

• cleansing the affected area without irritation

• limiting bacterial proliferation

• soothing itching and inflammation

• supporting natural skin regeneration

• promoting gentle healing

Its mild formulation respects the horse’s skin sensitivity, even when it is already irritated or weakened.

Arbalou Herbal Spray: protection and prevention of recurrences

Complementary to Arbalou Herbal Beauty, Arbalou Herbal sprayl helps protect the skin from moisture and strengthens its natural resistance. It is easy to apply, non-sticky, and forms a natural barrier that helps prevent the return of lesions.

It is especially useful:

• during wet seasons

• for horses living outdoors

• for areas exposed to friction (under the saddle or pad)

• to protect already weakened skin

The Herbal spray also helps maintain healthy skin after healing, reducing the risk of recurrence often observed in sensitive horses.

How to support a horse with dermatophilosis daily ?

Beyond natural care, several measures are essential to optimize recovery:

• reduce prolonged exposure to moisture

• use gentle, non-aggressive grooming

• regularly ventilate the stable

• clean and dry equipment in contact with the skin

• avoid wet or dirty blankets

• monitor the progression of lesions

Veterinary advice may be necessary if the infection is extensive, worsening, or if the horse shows signs of significant discomfort.
