What is happening inside the hoof
The horse's pedal bone is suspended inside the hoof capsule by a delicate, interlocking tissue called the laminae, and laminitis is the inflammation and weakening of that tissue. When the laminae fail, the bone they are holding can begin to rotate or sink within the hoof under the horse's own weight, which is why laminitis is both so painful and so time-critical: the pain is the warning, but the structural damage is the emergency. It most often strikes ponies and easy-keeping horses turned out on rich grass, horses whose feed changes abruptly, and animals already carrying the kind of cresty-necked, overweight condition that creeps up over a season. Both front feet are usually affected together, sometimes all four, and hind feet alone are less common. Because early treatment gives the best chance of limiting damage, the signs below should always be read as act-now rather than watch-and-wait.
The stance and the movement
Laminitis changes posture before it changes anything else. The classic picture is a horse rocking his weight backwards: front legs pushed out in front of him, hind legs camped underneath to take the load, heels bearing what the toes cannot. Standing on soft ground or bedding he may shift from foot to foot, lift one front foot then the other, or spend far longer than usual lying down — and resent being asked to get up. Walked out, he takes short, careful, pottery steps, lands heel first, and is visibly worse on hard or stony ground and when asked to turn in a tight circle, where he may almost pivot on his hindquarters to avoid loading the fronts. Feel the hooves: laminitic feet are often warm, sometimes noticeably hot, and the digital pulse at the fetlock, faint in a healthy foot, can throb strongly under your fingers.
The subtler presentations owners miss
Not every case announces itself with the full stance. A pony who is simply a bit footy for a day after the spring grass flushes, a horse who shortens his stride downhill or starts choosing the verge over the track, a cob who becomes reluctant to go forward or plants his feet at the yard gate — all of these get explained away as laziness, stubbornness or the farrier's recent visit, and sometimes they are. But laminitis at this early, shifting stage is exactly when treatment does the most good, and a cresty neck, a history of previous episodes, or a recent feed change should push any footiness straight onto the vet's radar. Rings on the hoof wall that widen towards the heel, a stretched white line at the next trim, and a sole that has dropped flatter are the slower, written-down evidence of episodes that have already happened.
First actions while the vet is coming
Phone the vet as soon as you suspect laminitis — this is an urgent call, not a routine one. Move the horse the shortest possible distance onto deep, soft bedding in a stable, and if he will not walk, bring the bedding and the vet to him rather than forcing the issue, because every step on failing laminae can do harm. Take him off grass and rich feed entirely; plain hay, soaked to reduce its sugars, is the usual holding diet while you wait. Do not ride, lunge or turn him out to walk it off, and resist giving stored pain relief before the vet has examined him, since masking pain can let him move more than his feet can afford. Once the vet has set the plan, the work becomes routine care repeated without a miss — soaked feeds, deep-bed checks, weight watching — and assigning those jobs through KinsLe Care Teams, with each task timestamped as it is done, keeps a long box rest consistent across everyone on the yard.
