Pre-Purchase Vetting: What Actually Gets Checked?
An opinion for a stated purpose, not a warranty.
It is not a pass, a guarantee, or a full scan, and knowing the difference changes how much weight “he vetted sound” deserves.
A vetting reduces your risk.
It does not remove it.
The pre-purchase examination (a “vetting” or PPE), is one of the few points in buying a horse where you pay for an expert to look on your behalf. It is worth understanding what that expert is actually doing, because the exam is widely misread in both directions: treated as a rubber stamp when it clears a horse, and as a disaster when it turns up something a knowledgeable buyer would have shrugged at.
What a vetting is, and isn’t
A vetting is a structured clinical examination carried out for the buyer. Once you commission it, you, not the seller, are the vet’s client, and the vet’s job is to give an opinion on whether anything they find is likely to prejudice the horse’s suitability for the specific use you describe. A finding that would rule a horse out for affiliated eventing can be irrelevant for light hacking, so the vet needs an honest account of what you intend to do and how experienced a rider you are.
Three things it is not. It is not a pass-or-fail test, good vets report findings and advise on the risk they represent. It is not a guarantee of future soundness. A horse can vet well and pull a suspensory the following month. And it is not a whole-body scan: a standard vetting is a hands-on clinical examination, not imaging. It is also an assessment at one moment. The horse’s management, workload and even the weather that week all shape what the vet sees.
Ask the vet to record your intended use precisely: “low-level dressage and hacking, novice adult rider,” not “general riding.” The whole opinion is written against that sentence, and a vague sentence produces a vague opinion.
The five stages, and what each is for
The widely used British model, set out in the joint BEVA and RCVS guidance, runs in five stages and takes around two hours. Each stage exists to catch something the previous one can’t.
The identity of the horse is confirmed against its passport and microchip at the start. Everything after that builds a picture: stage 1 finds what is visible standing still, stage 2 shows how the horse moves before any effort, stage 3 loads the system so heart, wind and subtle lameness have somewhere to hide less easily, and stages 4 and 5 look for what the work left behind. Leave any stage out and you lose whatever only that stage reveals.
Why a two-stage vetting isn’t half a vetting
A two-stage, or “limited,” vetting stops after the in-hand trot-up. No ridden exercise, no rest, no second trot-up. It removes exactly the strenuous-exercise phase where a heart murmur becomes audible, an abnormal respiratory noise appears, and a low-grade lameness that isn’t visible cold starts to show.
34% vs 68%: the rate at which a 2025 UK study found prejudicial issues in two-stage exams, against full five-stage exams.
Counter to the usual reasoning that a modest horse for a modest job needs only a modest check, the same dataset found horses intended for lower-level, leisure use were flagged as unsuitable more often than horses bound for strenuous competition. If a two-stage is all that’s available, treat “nothing found” with real caution.
Worth knowing“He vetted sound” is not one fact. The useful question is always: which vetting, for what job, and who chose the vet?
Flexion tests and circles: useful, not decisive
A flexion test holds a joint or limb firmly bent for up to a minute, then the horse is trotted straight off while the vet watches the first strides. Trotting in a tight circle on a firm surface is used the same way. Both are standard, but done at the vet’s discretion, and may be left out if age or temperament makes them unsafe.
They are screening tools, not diagnoses. A positive flexion (a few short strides afterwards), is common in sound horses. A clearly abnormal, sustained response is a reason to investigate further, often with imaging. A single hesitant step, on its own, usually isn’t. What you want is not a yes/no but an interpretation.
- ✓ How marked was it, one step, or lame for a circuit?
- ✓ Does it match a limb that looked off in stage 2 or 5?
- ✓ Same or different left and right?
- ✓ Consistent with the horse’s age, workload and shoeing?
- ✓ Does the vet want radiographs before forming an opinion?
What isn’t included as standard
A standard vetting is a clinical examination. Anything that needs a machine is a separate procedure, usually at extra cost, arranged by agreement in advance or triggered by something the vet finds on the day.
Radiographs
Which views depends on the discipline and value. Many insurers require a set above a threshold, often around £15,000, before they’ll cover the horse fully.
Endoscopy
A camera passed up the airway to look at the larynx and windpipe. Done when there’s a respiratory noise or the job demands hard, fast work.
Ultrasound
Images tendons, ligaments and the suspensory apparatus. Not part of a routine vetting. Used to follow up a clinical suspicion.
Gastroscopy
The only way to confirm or rule out gastric ulcers. Never part of a standard PPE. Requires the horse to be starved first.
Full bloods
Haematology, biochemistry and muscle enzymes are extras. The standard vetting takes a sample only to store, see below.
None of this is a failing of the standard exam. Loading every horse with a full imaging work-up would make vetting unaffordable, so these stay optional by design. But “the vetting didn’t pick anything up” only covers what a vetting actually looks at. If a horse is expensive, destined for demanding work, or the clinical exam raised a question, the radiographs and scoping are where the real risk assessment happens, and funding them is your decision.
The blood sample, and the certificate
Near the start of the exam, before any sedation, the vet usually draws a blood sample and sends it for storage, typically around six months. It is not tested straight away. It exists so that, if a problem emerges soon after purchase that could have been masked on viewing day by pain relief or sedation, there is a sample to analyse retrospectively. It protects you after the fact. It tells you nothing on the day.
The certificate records the horse’s identity, the stages carried out, every relevant clinical finding, and the vet’s opinion on the balance of probabilities that the findings would, or would not, be likely to prejudice the horse’s use for the purpose you stated. Read the whole thing, not just the closing sentence: a horse can be reported as suitable and carry findings the vet expects you to keep an eye on.
If the examining vet has ever treated the horse or has a relationship with the seller, that must be disclosed and you must consent to them proceeding. A genuinely independent vet is the default for a reason.
Getting the most from it
Book it yourself, with an independent vet. Not the seller’s vet, not a name the seller suggested. Be present if you can, a lot of the value is in the conversation while the horse is in front of you. Describe the real job. Be specific about discipline, level and your own experience, and ask for the seller’s written permission for the vet to see the horse’s clinical history.
Decide about radiographs in advance. Know your insurer’s threshold and budget for them rather than being surprised on the day. Don’t read “suitable” as “perfect.” Ask the vet to talk you through the findings, and ask directly: knowing what you now know, would you buy it? You are paying for that opinion. Use it.
You’ll want your own headcollar, a hoof pick and a few basics with you at the vetting, and from the first day the horse comes home.
- 01A vetting is an opinion written against the specific use you describe, not a pass/fail or a guarantee.
- 02The five stages each catch something the others can’t. Stage 3 is where hearts, wind and hidden lameness show.
- 03A two-stage vetting drops the most revealing stages, and finds far less as a result.
- 04Flexion tests are discretionary screening tools. Interpretation matters more than the result.
- 05Radiographs, scoping, ultrasound and bloods are all extra and your decision to fund.
- 06The stored blood sample protects you after the fact. Read the certificate in full.
General editorial guidance, not veterinary advice. A vetting is an opinion for a stated purpose, not a warranty, commission and brief your own vet.
