Hoof Abscesses in Horses
Key takeaways
A hoof abscess is an accumulation of pus (infection) within a horse’s hoof, which can lead to severe lameness and more serious infections.
- Hoof abscesses can be caused by external factors such as extremely wet or muddy conditions, rapid changes in weather, or rocky ground
- They can also be a result of inadequate hoof care, poor hoof quality, or poor hoof conformation
- The most common symptom is severe lameness, with other signs including drainage of fluids from the affected hoof, swelling of the leg, and increased digital pulse in the affected limb
- Diagnosis is mostly based on clinical signs and physical examination; further diagnostic testing might be necessary to detect the source and depth of the infection
- Treatment involves opening the abscess to allow fluid drainage, cleaning the affected area, and keeping it clean
- In some cases, antibiotics are necessary to address the primary infection
- The prognosis is good for superficial infections and guarded for infections that run deeper

A closer look: Hoof Abscesses in Horses
Hoof abscesses are extremely common in horses.
The condition requires immediate veterinary attention as it can develop into a more serious infection of deeper structures within the foot.
With appropriate treatment, uncomplicated hoof abscesses usually resolve within 3-5 days.
Risk factors
Some abscesses have an acute, sudden onset while others may develop gradually and take more time to heal. Sometimes abscesses also recur.
Chronic abscesses can lead to more serious infections of other parts of the foot, which in turn can lead to secondary conditions such as bone death, bone infection, and tumors. Recurrent hoof abscesses are often a sign of another underlying condition.
Diseases affecting the immune system may make horses more susceptible to hoof abscesses.
Possible causes
Potential causes of hoof abscess:
- Rapid changes in weather
- Poor hoof quality
- Poor hoof conformation
- Inadequate hoof care
- Rocky ground
- Excessively wet or muddy conditions
- Trauma or injury
Main symptoms
Testing and diagnosis
The diagnosis is often based on clinical signs and physical examination alone, as hoof abscesses are self-evident. Blood work, urinalysis, and diagnostic imaging might be necessary to detect the root of the infection and to visualize deeper structures.
Steps to Recovery
Treatment consists of:
- Opening the abscess to allow fluid drainage
- Softening the hoof capsule by soaking the foot or using poultices to encourage rupture
- Protecting the foot to prevent debris from entering
In some cases antibiotics and anti-inflammatories are necessary. Cleanliness throughout the whole procedure is fundamental for an effective treatment.
Hoof abscesses usually last only a few days and might even rupture on their own.
The prognosis depends on the severity of the infection. Generally, superficial infections have a good prognosis. Infections that have penetrated deeper tissues have a more guarded prognosis. Abscesses can also recur following treatment, leading to a prolonged recovery.
Prevention
Good hoof care is the best way to prevent abscesses from developing. This includes frequent cleaning of the hoof, routine checkups, and maintaining a clean, dry pasture free of foreign objects.
After an abscess is drained, keeping the hole in the hoof free of debris can help prevent recurrence. Hoof abscesses are not contagious.
