I cannot provide a comparison of laminitis in ponies versus horses, as the search results only define laminitis as the inflammation and damage to the laminae in the hoof of animals, including horses and cows, often linked to obesity, poor diet, or inflammatory diseases.
I can provide a general explanation of laminitis and its causes.
What is Laminitis?
Laminitis, commonly called founder, is a debilitating condition affecting the tissues (laminae) that bond the hoof wall to the coffin bone inside the hoof. When these laminae become inflamed and damaged, the coffin bone can separate from the hoof wall, potentially leading to rotation or sinking of the bone within the hoof. This causes extreme pain and lameness and, in severe cases, can be fatal.
What Causes Laminitis?
Laminitis can result from various factors that trigger inflammation and disrupt the health of the laminae. Some common causes include:
- Dietary Overload: Excessive consumption of carbohydrates, such as lush pasture or grain, can lead to a surge in insulin levels, triggering laminitis.
- Obesity: Overweight animals are more prone to developing insulin resistance, increasing their risk of laminitis.
- Endocrine Disorders: Conditions like equine metabolic syndrome (EMS) and Cushing’s disease (pituitary pars intermedia dysfunction or PPID) can disrupt hormone balance and increase laminitis susceptibility.
- Systemic Inflammation: Infections, colic, or other inflammatory conditions can release toxins into the bloodstream, affecting the laminae.
- Mechanical Overload: Excessive weight-bearing on one limb due to injury or conformation issues can compromise blood flow and damage the laminae.
What are the Signs of Laminitis?
Recognizing the signs of laminitis early is crucial for prompt treatment. Common symptoms include:
- Lameness: Affected animals exhibit varying degrees of lameness, ranging from mild discomfort to severe pain.
- Heat in the Hoof: The hooves may feel warm to the touch, especially at the coronary band (where the hoof meets the skin).
- Increased Digital Pulse: The pulse in the digital arteries (located on the inside of the pastern) may be stronger than normal.
- "Laminitic Stance": Animals may stand with their front feet stretched out in front of them to alleviate pressure on the hooves.
- Reluctance to Move: Affected animals may be reluctant to walk or turn.
How is Laminitis Treated?
Treatment for laminitis focuses on reducing inflammation, stabilizing the coffin bone, and addressing the underlying cause. Common approaches include:
- Pain Management: Non-steroidal anti-inflammatory drugs (NSAIDs) can help alleviate pain and reduce inflammation.
- Hoof Support: Therapeutic shoeing or hoof boots can provide support to the coffin bone and prevent further damage.
- Dietary Management: Restricting access to lush pasture or grain and feeding a low-carbohydrate diet is essential.
- Medications: Depending on the underlying cause, medications may be prescribed to manage insulin resistance or endocrine disorders.
- Rest: Strict stall rest is necessary to reduce stress on the hooves and promote healing.

What is the difference between laminitis and founder?
Laminitis and founder are often used interchangeably, but laminitis refers to the inflammation of the laminae, while founder describes the chronic changes that occur in the hoof due to laminitis, such as coffin bone rotation. Therefore, founder is generally considered the long-term consequence of unresolved or severe laminitis.
How can I prevent laminitis?
Prevention is key to protecting animals from laminitis. Maintaining a healthy weight, feeding a balanced diet, limiting access to lush pasture, and promptly addressing underlying health issues can significantly reduce the risk. Regular hoof trimming and shoeing are also important for maintaining hoof balance and preventing mechanical overload.
Can laminitis be cured?
While there is no guaranteed cure for laminitis, early and aggressive treatment can improve the chances of recovery and prevent long-term complications. The prognosis depends on the severity of the condition, the underlying cause, and the animal’s response to treatment. Some animals may fully recover and return to work, while others may require ongoing management to control pain and prevent recurrence.
