Understanding Laminitis in Horses: Causes, Prevention, and Treatment Options

A Guide for Horse Owners and Caretakers

Laminitis is one of the most serious health concerns facing horses in Australia and around the world. Whether you care for a backyard pony or manage a professional stable, understanding this condition is vital for the wellbeing of your horses. In this blog post, we’ll break down what laminitis is, why it happens, the warning signs to watch for, and what you can do to prevent and manage it. With prompt action and the right knowledge, you can make a real difference in your horse’s life.

What is Laminitis?

Laminitis is a painful and potentially debilitating condition that affects a horse’s hooves. Specifically, it’s an inflammation of the sensitive laminae—the soft tissues that connect the hoof wall to the underlying bone (the pedal bone). When these tissues become damaged or inflamed, the bond between the hoof wall and the bone weakens, leading to pain, instability, and in severe cases, permanent lameness or even euthanasia. Laminitis requires prompt attention and careful management, as it can progress rapidly and have lifelong consequences for the affected horse.

Causes of Laminitis

There isn’t a single cause of laminitis; rather, it can be triggered by a range of factors. Some of the most common include:

• Dietary Issues: Excessive consumption of lush pasture, grains, or feeds high in sugar and starch can overload the digestive system, leading to changes that trigger laminitis.

• Obesity: Overweight horses are at greater risk, as excess body weight stresses the hooves and can disrupt metabolic processes.

• Metabolic Disorders: Conditions such as Equine Metabolic Syndrome (EMS) and Cushing’s Disease (PPID) increase a horse’s susceptibility to laminitis.

• Stress or Physical Trauma: Severe illness, injury, or excessive weight-bearing on one limb (for example, after an injury to another leg) can also lead to laminitis.

• Environmental Factors: Sudden changes in routine, hard ground, or standing on wet surfaces for long periods may contribute to the onset of laminitis.

Early Warning Signs

Recognising laminitis early can make a significant difference to your horse’s recovery. Look out for these warning signs:

• Reluctance to walk or move, especially on hard ground

• A characteristic “rocked back” stance, where the horse leans back to take weight off the front hooves

• Heat in the hooves or increased digital pulse (just above the hoof)

• Lameness or short, shuffling steps, often more pronounced after exercise or turning

• Frequently shifting weight from one hoof to another

If you notice any of these symptoms, don’t wait—early intervention is key.

The Importance of Prompt Veterinary Involvement

Laminitis is a true emergency. Rapid assessment and intervention by a qualified veterinarian can help limit the extent of damage and improve the chances of recovery. Your vet will diagnose the condition, identify potential underlying causes, and develop a tailored management plan. They may use diagnostic tools such as hoof testers, x-rays, and blood tests to guide treatment. The sooner you involve your vet, the better the outcome for your horse.

Prevention Strategies

While not all cases of laminitis are preventable, many can be avoided with proactive management:

• Monitor Diet: Avoid sudden changes in feed, limit access to lush pasture (especially in spring and autumn), and steer clear of sugary treats or excess grain.

• Maintain Healthy Weight: Keep your horse at an ideal body condition—neither overweight nor underweight. Regularly assess using a body condition scoring system.

• Manage Metabolic Health: Work with your vet to monitor and manage conditions like EMS and PPID, including appropriate medication and diet.

• Regular Hoof Care: Engage a skilled farrier for routine trimming and maintenance. Good hoof care supports overall hoof health and can help spot problems early.

• Minimise Stress and Injury: Provide a stable routine and avoid situations that could lead to injury or excessive weight-bearing on one limb.

Treatment Options

Treatment for laminitis is multifaceted and depends on the severity and underlying cause. Common approaches include:

• Pain Relief and Anti-inflammatories: Medications prescribed by your vet to manage discomfort and reduce inflammation.

• Dietary Management: Transition to a low-sugar, low-starch diet and restrict access to pasture or rich feeds.

• Hoof Support: Specialised shoeing or hoof boots may be recommended to support the hoof and reduce pain.

• Stable/yard Rest: Confinement to an extra soft, deeply bedded stable to limit movement and protect the hooves.

• Treating Underlying Conditions: Addressing metabolic disorders or other triggers as identified by your vet.

Each treatment plan should be tailored to the individual horse and regularly reviewed as they recover.

Recovery Timeframes

Recovery from laminitis varies widely, from a few weeks in mild cases to several months or even longer in severe instances. Key factors influencing healing include how quickly treatment begins, the severity of the laminitis, and whether underlying issues can be managed. Some horses may return to full work, while others may need ongoing management or may not regain full soundness. Regular check-ins with your vet and farrier are essential throughout recovery.

Risk of Recurrence

Unfortunately, horses who have had laminitis are always at increased risk of it happening again. This is especially true if the original cause isn’t identified or managed. Ongoing vigilance is essential: maintain dietary and weight controls, monitor for early warning signs, and keep up with regular vet and farrier visits. With careful management, many horses can enjoy a good quality of life post-laminitis, but it’s important to accept that the risk of recurrence remains.

Conclusion

Laminitis is a challenging and potentially life-threatening condition, but with early detection, prompt veterinary care, and proactive management, you can greatly improve your horse’s chances of recovery and long-term health. If you suspect laminitis or have concerns about your horse’s hoof health, don’t wait—contact your vet immediately. Your quick action could make all the difference.
