Should You Get a Pre-Purchase Exam Before Buying a Horse?

Should You Get a Pre-Purchase Exam Before Buying a Horse?

By Dr Duncan Houston

Buying a horse is exciting, emotional, expensive, and occasionally a brilliant way to turn your bank account into hay.

A pre-purchase exam is one of the best ways to slow the process down and look at the horse clearly before you commit. It does not tell you whether the horse is “good” or “bad.” It tells you what your veterinarian can find on that day, how those findings may affect the horse’s suitability for your intended use, and what level of risk you may be accepting.

The key is understanding what a pre-purchase exam can reveal, what it cannot promise, and how to use the results sensibly.

Quick Answer

A pre-purchase exam is a veterinary assessment performed before buying a horse to evaluate the horse’s current health, soundness, and suitability for the buyer’s intended use. It is not a pass-or-fail test and it cannot guarantee future soundness, performance, behaviour, or disease risk. The buyer must make the final decision, using the vet’s findings, the horse’s history, price, intended job, risk tolerance, and any extra tests such as radiographs, bloodwork, endoscopy, or reproductive evaluation. AAEP states that the buyer is responsible for deciding whether the horse is suitable for the intended use, and Cornell describes a PPE as a single-day assessment rather than a guarantee of future health. (AAEP)

What Is a Pre-Purchase Exam?

A pre-purchase exam, often called a PPE or horse vetting, is a veterinary examination requested by the potential buyer before completing the purchase.

The aim is to assess the horse’s current health, soundness, and medical risk in relation to what the buyer wants the horse to do. A pony for quiet trail riding, a young dressage prospect, a high-level jumper, a broodmare, and a racehorse do not all carry the same risk profile.

Merck describes a horse PPE as a veterinary examination used to assess general health, soundness, temperament, and appropriateness for the buyer’s intended use. It also notes that PPEs can range from a basic physical and soundness exam to a highly comprehensive exam with ridden assessment, imaging, lab testing, and video documentation. (Merck Veterinary Manual)

The most important point is this:

A PPE is not a guarantee. It is a risk assessment.

That distinction protects buyers, sellers, vets, and the horse.

A Pre-Purchase Exam Is Not Pass or Fail

This is where many buyers get confused.

Your vet should not simply say “pass” or “fail.” That is not really how a good PPE works.

The vet’s job is to examine the horse, identify current findings, explain what those findings may mean, discuss risk, and recommend further testing where appropriate. The buyer then decides whether those risks are acceptable.

Cornell explains that veterinarians evaluate the risk associated with the purchase for the horse’s intended use, rather than giving a passing or failing grade. RCVS similarly states that a PPE is an assessment at the time of examination and is an indication, not a guarantee, of suitability for intended use. (Cornell Vet College)

In practice, I think of PPE findings in three broad categories:

Finding type	What it means for the buyer
Low-significance finding	Worth knowing, but unlikely to affect the intended use
Manageable risk	May be acceptable depending on price, use, treatment, insurance, and buyer expectations
Major concern	Could affect safety, soundness, performance, resale, welfare, or long-term costs

A horse does not need to be perfect to be worth buying.

But you do need to know what you are buying.

Why the Intended Use Matters So Much

The same finding can mean different things for different buyers.

A mild hock change may be acceptable in a low-level pleasure horse but more concerning in a competitive jumper. A respiratory noise may matter more in an eventer than in a quiet companion horse. A reproductive abnormality may not matter at all in a gelding for trail riding, but it matters a lot in a mare being bought for breeding.

Before the exam, tell your vet exactly what you want the horse for.

Be specific:

• Trail riding

• Pony club

• Show jumping

• Dressage

• Eventing

• Racing

• Breeding

• Driving

• Endurance

• Showing

• Children’s mount

• Companion horse

• Rehabilitation or resale project

AAEP’s reporting guidelines state that purchase examination findings should be considered by the buyer as part of a business judgment, with the veterinarian reporting findings and qualified opinions rather than deciding suitability for the intended purpose. (AAEP)

That is the whole point of the PPE: risk in context.

What Should Happen Before the Exam?

A good PPE starts before the vet touches the horse.

The buyer should discuss:

• Intended use

• Budget

• Competition goals

• Previous experience

• Risk tolerance

• Insurance needs

• Whether the buyer can manage chronic issues

• Whether the horse is being bought for a child, amateur, professional, or breeding program

• Whether the buyer wants radiographs or other diagnostics

• Whether the buyer wants drug screening or blood storage

The seller should be asked to provide:

• Age and identity documents

• Competition history

• Previous veterinary records where available

• Vaccination history

• Dental history

• Deworming or faecal egg count history

• Farrier history

• Lameness history

• Surgery history

• Medication history

• Current supplements and treatments

• Behavioural concerns

• Any known vices

Merck recommends asking the seller to disclose medical and surgical history, along with recent preventive care such as shoeing, vaccinations, deworming, and dentistry. Cornell also notes that gathering information from the seller, including medications, recent work level, lameness issues, and routine healthcare dates, is an important first step. (MSD Veterinary Manual)

If the seller refuses to release records, that does not automatically mean something is wrong, but it does change the level of uncertainty.

Who Should the Vet Work For?

Ideally, the vet performing the PPE should work for the buyer.

That matters because the buyer is the person taking on the risk.

A conflict of interest can arise if the examining vet regularly treats the horse, works for the seller, has a close professional relationship with the seller, or has already been involved in the horse’s care. AAEP’s ethics guidance states that the veterinarian should make clear they are working for the buyer, should encourage the buyer to obtain previous medical records, and should disclose prior familiarity or relationships that could create a conflict. (AAEP)

This does not mean the seller’s vet can never perform a PPE. In some areas, options are limited. But transparency matters.

If you are spending serious money, use an independent vet where possible.

What Is Included in a Basic Pre-Purchase Exam?

The exact structure varies by country, vet, discipline, facilities, and buyer request. Merck notes that PPEs are not standardised in the United States and can vary widely by practitioner, price, and horse discipline. (Merck Veterinary Manual)

A typical PPE may include:

• Identification check

• General physical exam

• Heart and lung auscultation

• Eye exam

• Basic oral and dental assessment

• Skin and body condition check

• Limb palpation

• Hoof assessment

• Back and neck assessment

• Conformation review

• Walk and trot in hand

• Circles on hard and soft surfaces where appropriate

• Flexion tests

• Lunge assessment where suitable

• Ridden or strenuous exercise assessment where suitable

• Post-exercise heart and respiratory assessment

• Repeat trot-up after exercise

• Discussion of findings and risk

The Royal Veterinary College describes the five-stage PPE as including a clinical exam at rest, walk and trot in hand with flexion tests, strenuous exercise, a rest period, and a second trot-up to check whether exercise has worsened a subtle lameness issue. (Royal Veterinary College)

The exam is only as good as the conditions allow. Poor footing, bad light, no safe area to trot, no rider, no dark stable for eye exam, or a horse that cannot be exercised can all limit what the vet can assess.

Two-Stage vs Five-Stage Vetting

In some countries, PPEs are commonly described as two-stage or five-stage vettings.

A two-stage vetting usually includes:

1. Examination at rest

2. Walk and trot in hand

A five-stage vetting usually adds:

1. Strenuous exercise

2. Rest period

3. Second trot-up after exercise

RCVS states that PPEs are based on a recognised two-stage or five-stage examination, though not every stage may be completed in every case. RVC notes that a limited two-stage examination may not reveal conditions that could have been discovered during a full five-stage examination. (Royal College of Veterinary Surgeons)

The short version:

A two-stage exam is cheaper and quicker, but it gives less information.

For a low-value companion horse, a limited exam may be reasonable. For a competition horse, young prospect, expensive horse, or horse intended for hard athletic work, a more complete exam is usually smarter.

What Extra Tests Might Be Recommended?

Optional tests depend on the horse, intended use, findings, budget, and buyer risk tolerance.

Common additional diagnostics include:

Test	Why it may be useful
Radiographs	Assess joints, feet, spine, or areas of concern
Ultrasound	Evaluate tendons, ligaments, soft tissue swelling, or reproductive structures
Endoscopy	Assess airway function, larynx, guttural pouches, or upper respiratory concerns
Bloodwork	Screen general health, inflammation, organ function, or systemic concerns
Drug screen or stored blood	Check later for sedatives, pain relief, or anti-inflammatories if concerns arise
Reproductive exam	Useful for breeding mares or stallions
ECG or cardiac ultrasound	Used when heart rhythm or murmur concerns are present
Ophthalmic testing	Useful if eye abnormalities are seen
Genetic testing	Relevant in some breeds or breeding decisions

AAEP’s reporting guidelines specifically mention tests such as X-rays, endoscopy, blood, drug testing, EKG, rectal examination, nerve blocks, and laboratory studies as examples of recommended tests that may be recorded if not performed at the buyer’s request. (AAEP)

RVC also notes that additional diagnostic tests such as X-rays, ultrasound, and respiratory endoscopy may be performed depending on the intended use or insurance requirements. (Royal Veterinary College)

The decision should not be “do every test possible” or “do nothing extra.”

The decision should be: what risk are we trying to understand?

Should Every Horse Have X-Rays?

Not every horse needs radiographs, but many buyers should at least discuss them.

Radiographs are more likely to be useful when:

• The horse is expensive

• The horse is young and being bought for future performance

• The horse is intended for jumping, racing, eventing, or high-level sport

• There is lameness or flexion concern

• There is joint swelling

• There is poor hoof balance or foot concern

• There is a known history of injury

• Insurance requires imaging

• Resale value matters

• The buyer has low tolerance for risk

Radiographs can identify some bony changes, but they do not predict every future problem. Some radiographic findings never cause clinical issues. Some horses with clean radiographs still go lame. Some horses with imperfect radiographs perform well for years.

Merck notes that comprehensive PPEs often identify some abnormal findings in almost every horse, and veterinarians must use clinical experience and current evidence to interpret those findings for the buyer. (Merck Veterinary Manual)

That is the art of PPE interpretation.

The image is only part of the answer. The horse, job, history, exam findings, and buyer’s risk tolerance matter too.

What About Drug Testing?

Drug testing or stored blood can be useful when there is concern that sedatives, pain relief, or anti-inflammatories may have affected the exam.

This is particularly relevant if the horse seems unusually quiet, behaves differently from its trial ride, has inconsistent lameness findings, or if the purchase is high-value.

RVC states that a blood sample is taken and stored for six months in its PPE process, and that it can be used later if concerns arise about substances such as sedatives, painkillers, or anti-inflammatories that may have masked conditions at the time of vetting. (Royal Veterinary College)

In practice, I like buyers to discuss this before the exam. If you want blood stored or tested, say it clearly.

Do not wait until after the sale and then wish you had asked.

Risk Framework: How Worried Should You Be About PPE Findings?

Low Risk

Low-risk findings are minor, stable, and unlikely to affect the horse’s intended use.

Examples may include:

• Small cosmetic blemish

• Mild conformation variation with no lameness

• Old superficial scar

• Minor dental points needing routine care

• Mild hoof imbalance that is manageable with farriery

• A finding that is common, stable, and clinically insignificant for that job

Action: Discuss the finding with your vet, document it, and decide whether it affects price, insurance, management, or future care.

Moderate Risk

Moderate-risk findings may matter depending on the horse’s job, price, and your plans.

Examples may include:

• Mild lameness only after flexion

• Mild joint effusion

• Mild respiratory noise

• Hoof conformation concerns

• Previous injury history

• Manageable dental disease

• Mild radiographic changes

• Behavioural concern under saddle

• Asymmetry or stiffness that needs further assessment

Action: Pause before buying. Consider further diagnostics, a specialist opinion, negotiation, insurance implications, or a trial period if available.

High Risk

High-risk findings are more likely to affect soundness, safety, performance, welfare, or long-term cost.

Examples may include:

• Current obvious lameness

• Significant back pain

• Neurological signs

• Significant eye disease

• Concerning heart murmur or arrhythmia

• Significant respiratory abnormality

• Suspicious medication or sedation concern

• Major radiographic abnormalities

• Severe dental disease

• Unsafe behaviour

• History inconsistent with exam findings

Action: Do not rush. Get further diagnostics, a second opinion, or walk away if the risk does not match your budget, experience, or intended use.

Critical Risk

Critical findings are serious enough that purchase should usually stop until fully investigated.

Examples include:

• Severe lameness

• Ataxia or suspected neurological disease

• Serious heart abnormality

• Severe respiratory compromise

• Severe eye disease affecting vision

• Evidence of systemic illness

• Severe unsafe behaviour

• Suspected recent masking medication

• Major undisclosed surgery, injury, or disease

• Findings incompatible with the horse’s intended use

Action: Pause the sale. This is not the time for emotional maths, such as “but he has kind eyes and I already bought the saddle pad.”

What Problems Can a PPE Help Identify?

A PPE may help reveal:

• Current lameness

• Joint pain

• Hoof pain

• Back or neck pain

• Poor conformation relevant to intended use

• Heart murmurs or rhythm abnormalities

• Respiratory abnormalities

• Eye disease

• Dental disease

• Skin disease

• Poor body condition

• Neurological concerns

• Old injury or surgical evidence

• Behavioural or handling concerns

• Signs that further testing is needed

A PPE may also show that a horse appears healthy and sound on the day of the exam.

That is valuable too.

But it still does not mean the horse will never become lame, sick, difficult, expensive, or allergic to your bank balance.

What Can a PPE Not Tell You?

A PPE cannot guarantee:

• Future soundness

• Future performance

• Future behaviour

• Future resale value

• That the horse will suit your riding ability

• That the horse will never need major treatment

• That a radiographic finding will or will not cause problems

• That a normal exam means no hidden issue exists

• That the horse will stay sound after training intensity changes

• That the seller has disclosed everything

RCVS is clear that the PPE is an assessment at the time of examination and an indication, not a guarantee, of suitability for intended use. Cornell similarly explains that a PPE cannot guarantee future health. (Royal College of Veterinary Surgeons)

This is why the buyer’s expectations matter.

If you want a perfectly risk-free horse, I have bad news: that animal does not exist. Even the imaginary unicorn probably has hock changes.

What Else Should Buyers Consider Beyond the Vet Exam?

The vet assesses medical risk. The buyer must also assess practical suitability.

Consider:

• Temperament

• Training level

• Rider experience

• Horse and rider match

• Management needs

• Ongoing costs

• Insurance availability

• Farrier requirements

• Transport behaviour

• Competition record

• Trial rides

• Behaviour in different environments

• Seller reputation

• Contract terms

• Return or trial agreement

• Disclosure in writing

A horse can be medically acceptable and still completely wrong for the buyer.

That is especially true for children, nervous riders, first-time owners, and amateurs buying athletic horses with more engine than steering.

When Should You Pause the Sale?

Pause the purchase if:

• The seller pressures you to skip the PPE

• Records are refused without reasonable explanation

• The horse is medicated before the exam without clear disclosure

• The horse is lame on the day

• The horse cannot be safely handled

• The horse cannot be exercised as expected

• There is a concerning heart, eye, neurological, respiratory, or lameness finding

• The horse’s history does not match the exam

• The horse’s behaviour changes dramatically between trial and vetting

• The seller will not allow recommended diagnostics

• You feel rushed into making a decision

A good horse will still be a good horse after you take time to think.

A bad decision becomes expensive very quickly.

What Should You Do Before Booking a PPE?

1. Choose your own vet

Use a vet who is working for you, not the seller. If using a vet who has treated the horse or seller, make sure any conflict is disclosed and acceptable to you.

2. Explain the intended use

Tell the vet exactly what you want the horse for. “Riding” is not enough. “Low-level adult amateur dressage with occasional clinics and trail rides” is much better.

3. Ask for records

Request medical, dental, farrier, vaccination, deworming, competition, and medication history.

4. Decide what diagnostics you want

Discuss radiographs, blood storage, drug testing, endoscopy, ultrasound, reproductive exam, or other tests before the appointment.

5. Be present if possible

Being present helps you understand the findings and ask questions. If you cannot attend, arrange live video, photos, videos, and a direct call with the vet.

6. Clarify communication

Make sure the vet reports directly to you. Trainers and agents can help, but you should still understand the medical findings yourself.

What Should You Ask the Vet After the Exam?

Useful questions include:

• What were the main abnormal findings?

• Are these findings common or concerning?

• How might they affect my intended use?

• Would you recommend further diagnostics?

• Are radiographs needed?

• Should blood be stored or tested?

• Is this a management issue or a performance risk?

• Could this affect insurance?

• Could this affect resale?

• What would you monitor over time?

• What questions should I ask the seller?

• Is there anything you were unable to assess properly?

The most useful question is often:

“If I buy this horse, what problem am I most likely to be managing?”

That cuts through a lot of noise.

Common Mistakes Buyers Make

Skipping the PPE because the horse seems perfect

A lovely trial ride does not replace a veterinary exam. Adrenaline and hope are not diagnostic tools.

Treating the PPE as pass or fail

A PPE is a risk assessment. Some findings are acceptable in one horse and unacceptable in another.

Not telling the vet the intended use

Your vet cannot interpret risk properly if they do not know what the horse is being bought to do.

Declining radiographs to save money on an expensive horse

Saving money on diagnostics can become very expensive if the horse later has a problem that could have been identified.

Ignoring conflict of interest

Use an independent vet where practical, or make sure any existing relationship is fully disclosed.

Letting the seller control the process

The buyer is paying for information. The vet should communicate findings to the buyer.

Buying emotionally after concerning findings

It is fine to love the horse. It is not fine to ignore the report because the horse nuzzled your jacket.

Not asking about insurance

Some findings may affect exclusions, premiums, or insurability. Check before purchase.

How To Reduce Your Risk When Buying a Horse

You cannot remove all risk, but you can reduce it.

Practical steps include:

• Use a buyer-appointed vet

• Be clear about intended use

• Get previous records where possible

• Attend the exam if you can

• Request a written report

• Consider radiographs for performance or higher-value horses

• Consider blood storage or drug testing

• Ask about insurance before buying

• Use a written sale contract

• Avoid rushing under pressure

• Take your trainer’s input seriously, but do not let training opinion replace veterinary findings

• Walk away if the risk is wrong for your situation

The best purchase decisions combine veterinary assessment, trainer input, records, rider suitability, price, and a very honest conversation with yourself.

Can you manage this horse if the finding becomes a problem?

Can you afford the likely care?

Is this horse suitable for your actual riding life, not your fantasy Olympic montage?

That last one stings, but it saves people.

FAQs

Is a pre-purchase exam worth it?

Yes, especially if the horse is being bought for riding, competition, breeding, resale, or significant money. A PPE cannot guarantee the future, but it can identify current problems and help you make a more informed decision.

Can a horse fail a pre-purchase exam?

Strictly speaking, a PPE is not a pass-or-fail exam. The veterinarian reports findings and discusses risk. The buyer decides whether the horse is acceptable for the intended use.

Should I get X-rays during a horse pre-purchase exam?

Radiographs are worth discussing for performance horses, expensive horses, young prospects, horses with lameness findings, or horses where insurance and resale matter. They are not always necessary for every purchase, but they can reveal important bony changes.

What is the difference between a two-stage and five-stage vetting?

A two-stage vetting usually includes an examination at rest and in-hand movement assessment. A five-stage vetting adds exercise, a rest period, and a second trot-up after exercise, making it more likely to reveal some issues that only appear or worsen with work.

Who should pay for the pre-purchase exam?

Usually, the buyer pays, because the exam is performed for the buyer’s benefit. The buyer should choose the vet where possible and should receive the report directly.

Final Thoughts

A pre-purchase exam is not there to ruin your dream horse.

It is there to make sure your dream horse does not become a surprise financial, medical, or emotional disaster.

The best PPE does not simply ask, “Is this horse sound today?” It asks a better question: “What risks are we seeing, how do they matter for this buyer, and what information do we still need before making a decision?”

Some horses with findings are still sensible purchases. Some clean-looking horses are not suitable. Some risks can be managed. Some should make you walk away.

A good vet does not buy the horse for you. They give you the medical clarity to make a better decision.

And in horse buying, clarity is worth far more than wishful thinking.
