Equine Veterinary Records: What to Track and Why It Matters (2026 Guide)

By Brian Bickell, who raises paint and quarter horses at Bickell Ranches in Stillwater, Oklahoma. He started keeping obsessive horse records after an insurance claim went sideways — and built HorseBook so nobody else has to learn that lesson the hard way.

Somewhere in your barn, truck, or kitchen drawer, there's a stack of vet receipts. Maybe there's a binder with some of them filed. Maybe there's a folder on your phone labeled "horse stuff" with sixty photos in no particular order.

You know you should be keeping better records. Every vet, every barn manager, every experienced horseperson has told you. But nobody explains what to actually track, why the details matter, and how to make the records useful rather than just another pile of paper.

That's what this guide is for.

Educational, not veterinary advice. This is a record-keeping framework, not a care protocol. Your vet is the one making clinical decisions for your specific horse — this guide just helps you hand them better information when they do.

The Nine Categories of Records

1. Vaccination Records

What to track: Date, product name (brand, not just "flu shot"), manufacturer, lot/batch number, route (IM/IN/SQ), injection site, administering vet, adverse reactions, next due date.

Why the details matter:

The lot number is the single most important detail most owners skip. If your horse has an adverse reaction, the USDA Center for Veterinary Biologics needs the lot number to investigate. Without it, they can't link the reaction to a production batch or issue a recall. Your vet records it. Make sure you get a copy.

The injection site matters because you should rotate locations between visits. If you put three vaccines in the same spot and your horse develops a reaction, you can't identify the culprit. Record "left neck" or "right pectoral" every time.

For the full schedule of what vaccines your horse needs and when — including AAEP core vaccines, risk-based vaccines, foal schedules, and competition requirements — see our complete vaccination guide.

2. Parasite Management

What to track: Fecal egg count (FEC) results with date, classification (low/moderate/high shedder), dewormer product used, dosage, date administered, and fecal egg count reduction test (FECRT) results.

Why it matters: The AAEP now recommends targeted deworming based on individual FEC results, not calendar rotation. Without records, you're either over-treating (accelerating drug resistance) or under-treating (leaving your high shedders as a parasite reservoir for the whole barn). About 50% of horses are low shedders who only need 1–2 treatments per year.

3. Dental Care

What to track: Date, procedures performed (floating, extractions, caps removed), specific findings (hooks, ramps, waves, sharp points, missing or fractured teeth), sedation used.

Why it matters: Dental problems cause weight loss, colic, quidding, head-tossing, and resistance to the bit. The AAEP recommends exams within 30 days of birth, every 6 months until age 5 (when caps are shedding), then annually for mature horses. Recording specific findings over time reveals patterns — a horse that consistently develops hooks on one side may have a jaw alignment issue your vet can address proactively.

4. Farrier and Hoof Care

What to track: Date, trim vs. shoe, shoe type, any corrective work, hoof angles or measurements if taken, notes on hoof quality and growth, hoof radiographs.

Why it matters: "No hoof, no horse" isn't just a saying. Changes in hoof growth rate, sole depth, heel height, or breakover point can signal systemic problems: early laminitis, nutritional deficiency, or Cushing's disease (PPID). Comparing measurements across trim cycles reveals patterns that are invisible in a single visit. Share these records with both your vet and farrier — they need to work from the same data.

5. Veterinary Exams and Sick Calls

What to track: Date, presenting complaint, exam findings (vitals, palpation, auscultation), diagnosis, treatments administered, prescriptions, follow-up plan.

Why it matters: Establishing baselines is critical. Take your horse's temperature twice daily for several days to know its normal range — the textbook says 99.5–101.5°F, but individual horses vary. A horse whose normal resting temp is 99.0°F running 101.0°F is more concerning than the number alone suggests. Same goes for heart rate and respiratory rate.

Every sick call builds a medical history that helps your vet diagnose future problems. "This horse colicked twice last fall after feed changes" is diagnostic gold. "I think he colicked once, maybe?" is not.

6. Surgeries and Hospitalizations

What to track: Date, facility, procedure, surgeon, anesthesia details, complications, pathology results, post-op instructions, rehabilitation timeline.

Why it matters: Surgical history is essential for pre-purchase exams, insurance underwriting, and any future procedures. A horse that had colic surgery has a different risk profile than one that hasn't. A horse with a history of anesthetic complications needs a modified protocol. Keep the full report, not a summary.

7. Lab Work and Diagnostics

What to track: Date, test type, results, reference ranges, veterinarian's interpretation. For imaging: store the actual files (DICOM format for radiographs, video clips for ultrasound) when possible, not just the report.

Why it matters: Serial bloodwork (CBC and chemistry panels run annually) reveals trends that single snapshots miss. A gradually rising insulin level over three years catches metabolic syndrome before clinical laminitis. Baseline radiographs of feet and hocks are invaluable for comparison if the horse goes lame later.

8. Medications

What to track: Drug name, dose, route, frequency, start and stop dates, reason prescribed, adverse reactions.

Why it matters: Weight-based dosing changes as body weight changes. Recording exact doses catches under-dosing (treatment failure, resistance development) and over-dosing (toxicity). For competition horses, medication records are essential for calculating drug withdrawal times — showing on a horse with a banned substance in its system can end a competitive career.

9. Weight and Body Condition Score

What to track: Monthly body condition score (BCS) using the Henneke scale (1–9), estimated weight (via weight tape or scale), and any notable fat deposits.

Why it matters: A single BCS is a snapshot. A trend line is diagnostic. A horse drifting from a 5 to a 7 over six months is developing a metabolic problem. A drop from 5 to 3 signals dental disease, parasitism, or chronic pain. Monthly scoring catches these trends before they become emergencies.

Watch for regional fat deposits — a firm cresty neck or tailhead fat pads are early warning signs of Equine Metabolic Syndrome and insulin dysregulation, the leading risk factors for laminitis.

Emergency Information: Always Accessible

Certain information needs to be available immediately, not buried in a filing system. Post it in the barn AND keep it on your phone:

• Current medications and dosages
• Known allergies and drug reactions
• Tetanus vaccination date (determines whether a wound booster is needed)
• Insurance policy number and 24-hour claims hotline
• Primary veterinarian — regular AND emergency/after-hours number
• Nearest equine referral hospital with driving directions
• Normal baseline vitals (temperature, heart rate, respiratory rate)
• Current Coggins status (needed for emergency transport)

When a barn manager finds your horse colicking at 2 AM, they need this information in seconds, not after a phone call to you. For a full emergency preparedness plan — including evacuation documents and proof of ownership — see our emergency preparedness guide.

Tip: HorseBook keeps all of this in one place — medical records, emergency info, documents, accessible from any device. When the barn manager needs your horse's medication list at 2 AM, it's on their phone, not in your kitchen drawer.

Who Needs Access

Your horse's records aren't just for you:

• Barn manager: Medication schedules, feed info, emergency contacts, known health issues
• Veterinarian: Complete medical history (past treatments, diagnostics, surgeries, drug reactions)
• Farrier: Hoof history, radiographs, lameness history, corrective shoeing notes
• Trainer: Exercise restrictions, medications, competition withdrawal periods
• Insurance company: Vaccination records, vet exam records, surgical reports (all required for claims)
• Buyer (at sale): The AAEP recommends full veterinary history transfer. Buyers should insist on it. See our buying and selling guide for what documents to request and provide.

The Real Cost of Bad Record Keeping

This isn't theoretical. Bad records cost horse owners real money:

Missed vaccine boosters. A lapsed primary series means restarting from scratch — 2–3 doses over weeks instead of one booster, with the horse vulnerable during the gap.

Insurance claim denial. The top reasons equine claims are denied include failure to report promptly (many policies require 24-hour notification), missing documentation, and inability to prove current vaccinations. Insurers routinely request the full medical history from treating veterinarians for mortality claims. Gaps in records weaken claims. Missing vaccination records can trigger "proper care exclusion" denials.

Competition entry blocked. USEF and FEI require documented vaccination records (influenza, EHV) for entry. Incomplete records mean the horse can't compete, and you've already paid entry fees and travel costs. See our show document checklist for exactly what's required by organization.

Duplicate or unnecessary deworming. Without FEC records, horses get dewormed on a calendar regardless of actual need. This accelerates drug resistance across the whole herd.

Inability to provide history to a new vet. When horses change owners, barns, or veterinarians, missing records force the new vet to start from scratch: repeating diagnostics, re-establishing vaccine series, and making treatment decisions without knowing prior drug reactions or chronic conditions.

How Long to Keep Records

The lifetime of the horse. All records should transfer with ownership when a horse is sold. Pre-purchase exam reports should be retained permanently. Breeding records are required by registries for verification. Retain radiographs for at least 3 years (some state veterinary practice acts require this for litigation protection), but there's no good reason to discard any equine medical record. Keep everything.

Getting Started

If you're starting from scratch, don't try to digitize ten years of records in one sitting. That's how record-keeping systems die on day one.

Start today, going forward. After the next vet visit, record the details. After the next farrier appointment, log it. Score body condition this weekend. Take five minutes after each event — that's all it takes.

Then, when you have a quiet afternoon, photograph the key documents that already exist: current Coggins, vaccination records, any recent bloodwork or radiographs. Get those into your system.

HorseBook makes that first step easy — scan a vet receipt or vaccine sticker and the record is created automatically. But whether you use an app, a spreadsheet, or a binder, the information in this guide is what you need to capture.

The best time to organize your horse's records was five years ago. The second best time is now.
