Yes, chronic laminitis can indeed cause deformities in a horse’s hooves. Laminitis involves inflammation and damage to the laminae within the hoof, and when it becomes a chronic condition, it can lead to significant and lasting changes in the structure and shape of the hoof. These deformities can severely impact a horse’s soundness and overall quality of life.
What is Laminitis?
Laminitis is the inflammation of the laminae, the soft tissue structures that attach the hoof wall to the coffin bone in a horse’s foot. This inflammation can cause extreme pain and, in severe cases, can lead to the separation of the coffin bone from the hoof wall, a condition known as founder. Chronic laminitis is a long-term condition that can result in permanent damage to the hoof.
How Does Chronic Laminitis Cause Hoof Deformities?
Chronic laminitis can cause several types of hoof deformities:
- Hoof Wall Rings: Uneven growth due to inflammation can cause visible rings or ridges on the hoof wall.
- Distorted Hoof Shape: The hoof may become wider at the heels than at the toe, leading to a "boxy" or "mule-footed" appearance.
- Dropped Sole: The sole of the hoof can flatten or even bulge downward due to the coffin bone’s rotation or sinking.
- Rotation of the Coffin Bone: In severe cases, the coffin bone can rotate within the hoof capsule, putting pressure on the sole and leading to further deformities.
What are the Risk Factors for Chronic Laminitis?
Several factors can increase a horse’s risk of developing chronic laminitis:
- Obesity: Overweight horses are more prone to metabolic issues that can trigger laminitis.
- Diet: Diets high in carbohydrates or sugars can disrupt the hindgut microbiome and lead to laminitis.
- Underlying Diseases: Conditions like equine metabolic syndrome (EMS) and pituitary pars intermedia dysfunction (PPID, or Cushing’s disease) are associated with increased laminitis risk.
- Inflammation: Diseases associated with inflammation can cause laminitis.
How is Chronic Laminitis Managed?
Managing chronic laminitis involves a multifaceted approach:
- Dietary Management: Restricting carbohydrate and sugar intake is crucial.
- Farrier Care: Corrective trimming and shoeing can help support the hoof and realign the coffin bone.
- Pain Management: Medications can help manage pain and inflammation.
- Exercise: Controlled exercise can improve circulation and promote healthy hoof growth.
What is the Long-Term Outlook for Horses with Chronic Laminitis?
The long-term outlook for horses with chronic laminitis varies depending on the severity of the condition and the horse’s response to treatment. Some horses can return to near-normal activity levels with proper management, while others may require ongoing supportive care to maintain comfort and soundness.

What are the early signs of laminitis in horses?
Early signs of laminitis can be subtle but may include increased digital pulse, heat in the hooves, reluctance to turn, and a shifting of weight between feet. Recognizing these signs early is crucial for prompt treatment and preventing chronic changes.
Can laminitis be cured completely?
While the acute phase of laminitis can sometimes be resolved, chronic laminitis often involves permanent damage to the hoof. Management focuses on minimizing pain, improving hoof health, and preventing further episodes.
How can I prevent my horse from getting laminitis?
Prevention strategies include maintaining a healthy weight, feeding a balanced diet low in carbohydrates and sugars, managing underlying metabolic conditions, and providing regular hoof care.
What type of bedding is best for a horse with laminitis?
Soft, supportive bedding such as shavings or straw can help cushion the hooves and reduce pressure on the sole. Avoid bedding that is too deep or allows the horse to sink, as this can exacerbate the condition.
How often should a horse with chronic laminitis be trimmed?
Regular trimming by a qualified farrier is essential to maintain proper hoof balance and support. The frequency of trimming will depend on the individual horse’s hoof growth and the severity of the deformities, but it is typically recommended every 4-6 weeks.
