Spring hoof threats for horses: mud fever, thrush, and bacterial infections

Wiosenne zagrożenia dla kopyt koni: gruda, gnicie strzałki i infekcje bakteryjne

Spring is one of the most challenging periods for horse hoof health. Melting snow, frequent rainfall, and muddy paddocks create ideal conditions for the growth of bacteria and fungi. As a result, horse owners increasingly face problems such as mud fever, thrush, and general bacterial infections within the hoof capsule.

This article provides a comprehensive overview of the most common spring hoof ailments and effective methods for their prevention and treatment.

Why is spring so problematic?

During the transitional period between winter and summer, several key risk factors arise:

  • Constant moisture – softens the hoof horn and weakens its structure
  • Mud and faeces – a source of anaerobic bacteria and pathogens
  • Variable temperatures – favour the proliferation of microorganisms
  • Limited hoof ventilation – especially with neglected hygiene

A humid environment causes tissue maceration, facilitating the penetration of microorganisms deep into the hoof structures and skin.

Mud fever (pastern dermatitis)

Mud fever is an inflammation of the skin in the pastern area, most often bacterial in origin (e.g., Dermatophilus congolensis), although it often has a mixed character (bacteria + fungi).

Symptoms:

  • scabs and erosions on the skin
  • swelling and soreness
  • weeping lesions
  • lameness (in advanced cases)

Predisposing factors:

  • prolonged exposure to mud
  • lack of limb hygiene
  • microtrauma to the skin
  • weakened immunity

Procedure:

  1. Thorough cleaning and drying of affected areas
  2. Gentle removal of scabs (after softening them)
  3. Application of antibacterial and antifungal preparations
  4. In severe cases – systemic antibiotic therapy

    🔎 Care support for mud fever

    In the treatment of mud fever, in addition to causal therapy, appropriate skin care support is essential. The product Excellent Horse Mud Fever (CLICK), designed for the care of sensitive, reddened, and damaged skin on horse legs, can be helpful.

    This preparation is particularly effective for:

    • rough and cracked skin around the pasterns and coronet,
    • changes resulting from prolonged exposure to moisture and mud,
    • skin requiring regeneration and protection.

    Thanks to the content of plant oils, vitamin E, lanolin, and zinc oxide:

    • it soothes irritation,
    • supports epidermis regeneration,
    • creates a protective layer limiting the effect of moisture,
    • prevents excessive skin dryness.

    It can be a valuable complement to daily care during treatment and in the prevention of mud fever recurrence.



Thrush

This is one of the most common hoof diseases in spring. It is caused by anaerobic bacteria that thrive in moist, contaminated environments.

Symptoms:

  • characteristic, putrid smell
  • black, soft tissue in the collateral grooves of the frog
  • soreness on pressure
  • deepened frog clefts

Mechanism:

Bacteria break down the horn tissue, leading to its degradation. In extreme cases, the process can extend to deeper structures, causing lameness.

Treatment:

  • daily hoof cleaning
  • removal of dead tissue (trimming)
  • application of disinfecting preparations (e.g., copper sulfate, iodine-based)
  • providing a dry environment

    🔎 Care support for thrush

    In the case of thrush, in addition to thorough cleaning and hoof correction, it is crucial to use preparations with drying and antibacterial properties. In practice, Excellent Horse Hoof Zinc Paste, a professional paste designed for the care of the frog and sole of the hoof (CLICK), works well.

    This preparation can be particularly helpful:

    • for soft, decaying frog tissue,
    • in deep, moist grooves,
    • in conditions of constant exposure to mud, urine, and manure.

    Thanks to the content of zinc oxide, copper and zinc chelates, organic acids, and tea tree oil:

    • it has a strong drying effect, limiting the growth of anaerobic bacteria,
    • it shows antibacterial properties and supports the cleansing of affected tissues,
    • it forms a protective layer against moisture and contamination,
    • thanks to its consistency, it adheres well and stays in the frog grooves.

    It can be used both as a supportive measure during treatment and preventively – especially during periods of increased humidity and risk of recurrence.




Bacterial infections of the hoof capsule

In spring, the following are also often observed:

  • white line disease
  • hoof abscesses
  • sole infections

Causes:

  • softening of the hoof horn
  • microcracks and separations
  • lack of regular trimming

Symptoms:

  • sudden lameness (abscesses)
  • deformations of the hoof wall
  • presence of empty spaces (separations)
  • tenderness on examination

Procedure:

  • prompt intervention by a farrier and/or veterinarian
  • drainage of abscesses
  • off-loading the affected structure
  • local treatment and improvement of environmental conditions

    🔎 Care support for hoof infections

    In the case of problems such as white line disease, microcracks, or weakening of the hoof horn structure, an important element of treatment is not only causal therapy but also appropriate, regular care supporting regeneration.

    As a complement to daily care, Excellent Horse neem oil balm (CLICK)—a nourishing preparation based on natural neem oil, which supports the condition of the hoof horn—works well.

    This preparation:

    • helps maintain proper hoof moisture levels,
    • supports the elasticity and resistance of the horn to cracks and chips,
    • improves the overall condition and appearance of the hooves,
    • can be used on the hoof wall, as well as the frog and coronet.

    Thanks to its ability to penetrate the hoof structure, it supports its regeneration and is a valuable element of prevention—especially in horses prone to dryness or brittleness of the horn.

    ❗ It should be emphasized, however, that this preparation does not replace causal treatment. In the case of infections, such as white line disease or abscesses, intervention by a farrier and/or veterinarian is necessary—including cleansing of affected tissues, hoof correction, and implementation of appropriate treatment.

    The balm can, however, be an effective support for daily care and an element of preventing recurrence of problems.


Mud fever – is it the same as pastern dermatitis?

The term "mud fever" is often used interchangeably with pastern dermatitis, but it refers more to the environmental aetiology than a specific disease entity.

It is a collective term for skin problems resulting from:

  • moisture
  • mud
  • presence of bacteria

In practice, it simply means pastern dermatitis caused by spring conditions.

Prevention – the key to healthy hooves

The most important element in combating spring problems is prevention.

1. Hygiene

  • daily hoof cleaning
  • checking the collateral grooves of the frog
  • washing and thoroughly drying the limbs

2. Environment

  • limiting access to mud (mats, paddock drainage)
  • clean, dry stalls
  • regular removal of manure

3. Trimming

  • regular farrier visits (every 4–6 weeks)
  • elimination of pockets conducive to infections

4. Immunity support

  • appropriate diet (biotin, zinc, copper)
  • avoiding excess sugar (important for metabolic problems)

Most common owner mistakes

  • leaving wet legs undried
  • too aggressive removal of scabs (aggravating lesions)
  • lack of regular trimming
  • ignoring the first symptoms
  • using random preparations without diagnosis

Summary

Spring is a period of increased risk of hoof and limb skin diseases. Moisture, mud, and the presence of pathogens create an environment conducive to the development of problems such as mud fever, thrush, and bacterial infections.

Key importance lies in:

  • prompt reaction to the first symptoms
  • maintaining hygiene
  • providing appropriate living conditions

Conscious prevention not only helps avoid costly treatment but, above all, ensures the horse's comfort and health throughout the season.
