A horse's digital pulse: what it means and how to feel for one

Most horse owners are told to “check the digital pulse” long before anyone shows them how. It gets mentioned in the same breath as laminitis, usually urgently, and then you’re left standing in a stable at seven in the morning squeezing a fetlock and wondering whether the thing you can feel is your horse’s pulse, your own, or nothing at all.

It’s a genuinely useful skill and it takes about ten minutes to learn. But it’s worth being clear from the start about what it tells you, because that’s where most of the confusion comes from.

What the digital pulse actually is

Blood reaches the hoof through the digital arteries, which run down either side of the pastern. You can feel that flow as a pulse where the arteries pass over bone, just as you can at your own wrist.

In a healthy, rested horse the pulse is faint — often you can’t find it at all, and that’s normal. What you’re looking for is not a pulse but a stronger pulse than usual, described as “bounding”: obvious, easy to find, thumping under your fingertips.

That strength is the signal. Inflammation inside the hoof increases blood flow to the foot, and because the hoof capsule is rigid, that extra flow is easy to feel in the arteries feeding it. So a bounding digital pulse means: something in that foot is inflamed.

It does not tell you what. Laminitis is the reason everyone worries, and it is the most serious, but a hoof abscess, a bruised sole, a nail bind after shoeing, or a puncture will all produce a bounding pulse too. The pulse tells you where to look and how urgently — not what you’ve found.

How to feel for one

Start with a sound horse on a normal day. This is the single most useful thing in this article. If the first time you ever feel for a digital pulse is the morning you think something’s wrong, you have no idea what that horse’s normal feels like, and you’ll either miss it or frighten yourself. Practise on all four feet, on a few different days, until “nothing much there” is a familiar sensation.

Get the horse standing square and calm. Not just come in from the field, not mid-fidget, not eating. Excitement, heat, and recent exercise all raise the pulse legitimately, and a horse dancing around on the yard will give you a reading you can’t interpret.

Find the spot. The easiest place for most people is the outside of the fetlock, slightly towards the back, where the artery runs over the sesamoid bone — a groove you can feel between the tendon and the bone. Some people find it more easily lower down, at the back of the pastern. Either works; use whichever one you can locate reliably on your own horse.

Use two or three fingertips, never your thumb. Your thumb has a strong pulse of its own, and a surprising number of “bounding pulses” turn out to be the person feeling their own heartbeat.

Press lightly. Firm enough to make contact, light enough not to flatten the artery. Too much pressure closes it off and you’ll feel nothing. If you find nothing at all, ease off slightly rather than pressing harder, and give it fifteen seconds — a faint pulse takes a moment to pick up.

Check all four feet, and compare. This is what makes the reading meaningful. One foot noticeably stronger than the other three points at that foot. Both fronts bounding, together, is the pattern most associated with laminitis and should be taken seriously straight away.

What to note alongside it

The pulse is one input, and it’s much more informative in company. While you’re there, check:

• Heat in the hoof wall, compared with the other feet and with what’s normal for that horse on that day of weather
• How the horse is standing — weight rocked back onto the heels, front feet stretched out in front, reluctance to pick a foot up, shifting from one to the other
• Whether it will walk, and how it moves on a turn, which is often where foot pain shows first
• Any recent change — new grass, a feed change, a shoeing three days ago, a stone bruise last week, a course of steroids

Write it down with the date. Foot problems are frequently a story about a trend rather than a single moment, and the same is true of subtler soundness problems — much like the timeline that makes hind-limb lameness legible, covered in how to tell if your horse is lame behind.

When to ring the vet

Do not sit on any of these:

• Bounding pulses in both front feet, particularly with heat, a reluctance to move, or a rocked-back stance. Treat this as a laminitis emergency and ring immediately — outcomes in laminitis are strongly tied to how early it’s caught. The Royal Veterinary College’s laminitis fact file is worth reading before you ever need it.
• A bounding pulse in one foot with heat and lameness. Often an abscess, which is usually far less serious, but it needs looking at rather than guessing at.
• Any severe or sudden lameness, with or without a pulse you can find.
• A pulse you’re unsure about in a horse that isn’t right. The uncertainty is the reason to call, not a reason to wait.

And the honest counterpart: a pulse you can’t find does not rule anything out. Some horses are hard to read, some hands take practice, and early laminitis can be present before the pulse is dramatic. If the horse looks wrong, the absence of a bounding pulse is not permission to leave it until tomorrow.

Where the technology fits

Nothing in what Stride does replaces a hand on a pastern — this is a physical skill and it’s worth having. What the app is for is the part people genuinely do lose: the record.

A check like this takes ten seconds to note down and nobody does it, because a notebook in a tack room is a notebook you lose. In Stride it’s a dated entry on the horse’s health timeline — what you felt, in which foot, with a photo of the stance or the foot if it’s worth having — sitting in the same place as the farrier visits, vet records and feed changes.

That matters because “his fronts have felt warm on and off for about a fortnight” is a much weaker thing to tell a vet than a fortnight of dated entries showing when it started, which feet, and what else changed that week.

What it can’t do is feel the pulse for you or tell you what’s causing it. It keeps what you observed, in order, so the phone call to your vet is a better one. The judgement stays where it belongs.

If you learn one new thing on the yard this month, make it this. Ten minutes on a sound horse now is what lets you trust yourself at seven in the morning when it matters.
