How to recognise the early warning signs before horses become laminitic

Pets

Most people picture laminitis as a horse rocked back on its heels, refusing to move. By that point, though, the condition has usually been building for a while.

The harder question is what comes before that. What does laminitis look like in week one, when it is still a vague sense that something is slightly off? Across yards and paddocks, the horses that recover best are almost always the ones whose owners noticed something small and acted on it. Here is what to look for.

What Laminitis Actually Is

In simple terms, the hoof wall is attached to the bone inside the foot by interlocking tissues called laminae. Laminitis is what happens when those tissues become inflamed, weakened or start to fail.

It is extremely painful, and in serious cases the bone can move within the hoof. That is why the early stages matter so much. Damage caught early is far more manageable than damage discovered late.

Why Catching It Early Changes Everything

This is not a rare problem affecting a handful of unlucky horses. In Great Britain, the annual incidence of equine laminitis is estimated at around 10%, according to the Royal Veterinary College.

Just as importantly, the understanding of what causes it has shifted. Most cases are now recognised as endocrine in origin, linked to insulin problems associated with equine metabolic syndrome or PPID, rather than the old picture of a horse gorging on spring grass. That changes what you watch for, because the earliest warning signs often show up in the horse’s body and behaviour well before the feet.

The Subtle Signs That Come First

Laminitis rarely appears without warning. In many cases, the earliest changes are so mild that they are easy to dismiss as stiffness, tiredness, or a horse simply having an “off” day. Learning to recognize these subtle clues can help you seek veterinary advice before the condition progresses and causes more significant damage to the hoof.

• A slightly shortened stride. The horse is not lame exactly, but the movement looks a little tight or careful, especially on hard ground.
• Reluctance to turn sharply. Turning in a tight circle puts more load on the front of the foot, so hesitation here often shows before straight-line lameness.
• Pottery, choppy steps. A stilted gait that some owners describe as walking on eggshells.
• Shifting weight while standing. Frequently swapping which front foot takes the load, or standing with the front feet slightly forward.
• Increased digital pulse. A stronger than usual pulse felt at the back of the fetlock, often in both front legs.
• Warmth in the hooves. Persistently warm feet, rather than warm on a hot day.

While none of these signs alone confirms laminitis, they should never be ignored, particularly if they appear together or develop over a short period. Early veterinary assessment can identify whether laminitis is developing or rule out other causes of lameness, giving your horse the best chance of a successful recovery.

What to Check on the Horse Itself

Because most cases are metabolic, the body often signals risk before the feet do. Look for weight gain, particularly a hard crest along the neck, fat pads behind the shoulders, and around the tail head. Watch for a horse that is suddenly holding condition on very little. In older horses, a coat that sheds late or unevenly, unexplained muscle loss over the topline, or increased drinking can point toward PPID.

Hooves also keep a record. Rings running around the hoof wall that are wider at the heel than the toe suggest previous episodes, as does a flattened or dropped sole. Understanding the risk pattern in laminitic horses helps explain why so much of the prevention work happens through diet and weight management rather than at the farrier’s visit.

Mad Barn has a detailed resource on laminitis in horses covering causes, risk factors, and management. If your horse fits the metabolic picture, ask your vet about testing insulin and ACTH. Knowing where a horse sits is far more useful than guessing.

The Risk Factors Worth Knowing

Some horses carry more risk than others, and knowing which category yours falls into changes how closely you watch.

• Native ponies and good doers who hold weight easily
• Horses already carrying excess condition
• Any horse with diagnosed EMS or PPID
• Horses with a previous laminitis episode, since recurrence is common
• Animals with unrestricted access to rich grazing

Season matters too, though less predictably than the old spring-grass model suggests. Sugar levels in grass rise with sunshine and cold nights, which means autumn can be as risky as spring.

What to Do If You Suspect It

Speed matters more than certainty here. You do not need to be sure before you act. Call your vet the same day rather than waiting to see how the horse looks tomorrow. Move the horse off grass and onto a deep, supportive surface, keeping walking to a minimum. Do not exercise a horse you suspect is developing laminitis, and avoid the temptation to trot it up repeatedly to check.

Keep forage available, since sudden feed restriction brings its own problems, and let your vet advise on what that forage should be.

Conclusion

Laminitis rarely arrives without warning. It arrives after a series of small signals that are easy to explain away individually. Learn your horse’s normal, get familiar with its digital pulse, keep a hand on its condition through the year, and take the metabolic side seriously. 

The owners who catch it early are not luckier than everyone else. They are simply the ones who noticed something minor and picked up the phone.
