Writing Honest Health and Vaccination Details in Your Listing

The health section of a puppy listing is where trust is won or lost. Buyers read it closely, compare it against what they know, and remember it if anything turns out to be wrong. Writing this section honestly is not only the ethical choice, it is the practical one. Accurate health and vaccination details attract serious buyers, reduce back-and-forth questions, and protect you if a disagreement ever arises.

This article offers general guidance on presenting health information clearly. It is not veterinary advice. Every claim you make in a listing should reflect your puppy's actual veterinary records, and buyers should always be directed to those records and to their own veterinarian for medical decisions.

Start with the records you actually have

Before you write a word, gather the paperwork for the specific puppy. That usually includes the vaccination record, the deworming log, any veterinary exam notes, microchip information, and results of any health testing done on the parents. Write your listing from those documents rather than from memory. If a date, product, or test is not written down somewhere you can point to, do not state it as fact.

Responsible breeders send buyers home with these records, and buyers increasingly expect them. Being able to show a vaccination and deworming history, a veterinary exam, and parent health testing is one of the clearest signals that you run a careful program.

A good rule of thumb: never write anything in the health section that you could not back up with a document if a buyer asked to see it today.

Describe vaccinations accurately

Vaccinations are the detail buyers scrutinize most, so be precise. State which vaccines a puppy has received, the date each was given, and note that a vaccination schedule continues after the puppy goes home.

Puppies follow a series, not a single shot. A common core schedule looks like this, though your veterinarian sets the exact plan for your region and litter:

• Around 6 to 8 weeks: first combination vaccine covering distemper and parvovirus.
• Around 10 to 12 weeks: a DHPP booster (distemper, adenovirus/hepatitis, parainfluenza, parvovirus), with optional vaccines based on risk.
• Around 16 to 18 weeks: a further DHPP booster and, at the appropriate age under local law, rabies.
• Around 12 to 16 months: boosters as advised by the veterinarian.

Non-core vaccines such as Bordetella, leptospirosis, Lyme, and canine influenza are given based on lifestyle and regional risk, so only list them if your puppy actually received them. In your listing, make clear which shots are done and which the new owner will need to continue. For example, note that a puppy has had its first two combination vaccines and that further boosters and rabies are still due on the veterinarian's schedule. That honesty prevents a buyer from assuming a puppy is fully vaccinated when it is not.

Deworming and parasite treatment

List deworming the same way: the dates given and, if you have it, the product used. Puppies are typically dewormed several times before going home. If a fecal test was run, you can note the result. Do not claim a puppy is parasite-free unless a veterinary test supports that statement; instead, describe the treatment history accurately.

Present health testing and guarantees clearly

If the parents have undergone health screening, such as hip and elbow evaluations, cardiac or eye clearances, or breed-specific DNA testing, name the specific tests and results and offer to share the certificates. Vague phrases like "fully health tested" mean little on their own. Specific, verifiable results mean a great deal.

If you offer a health guarantee, describe what it covers, what it does not, and for how long, and keep the listing language consistent with your written contract and the platform terms and conditions. A health guarantee is a written agreement that sets clear expectations for both sides. Overstating it in a listing and then narrowing it in the contract is exactly the kind of mismatch that damages trust and invites disputes.

Disclose honestly, including the imperfect

Honest disclosure includes anything a reasonable buyer would want to know. If a puppy has a minor known condition, an umbilical hernia, a mild heart murmur being monitored, a healed injury, or a cosmetic fault, state it plainly. Many buyers will still be interested, and they will respect you for the candor. Hiding a known issue almost always surfaces later, at the first vet visit, and turns a manageable conversation into a broken relationship.

Be equally careful with breed-specific health context. Every breed has predispositions worth understanding, and pointing buyers to reliable breed information helps them prepare. You can link to the relevant page in our breed guides so buyers can read about the breed's typical health considerations alongside your listing.

Defer medical interpretation to professionals. Your job is to report what the records say and what your veterinarian observed. The buyer's veterinarian is the right party to examine the puppy and advise on its ongoing care.

Microchip, registration, and identity details

Health details sit alongside a few identity records buyers rely on. If a puppy is microchipped, note that it is chipped and be prepared to transfer the registration to the new owner; the chip is only useful if the contact details are updated. If the puppy comes with registration paperwork or a pedigree, describe accurately what is and is not included, and whether it is a full or limited registration. Misstating registration status is a common source of friction, so be precise. These records, taken together with the vaccination and deworming history, form the paper trail that a careful buyer expects to receive at pickup.

Give buyers a plan for going home

An honest health section does more than list what has happened; it prepares the buyer for what comes next. Note when the next vaccine boosters are due, when the puppy should next be seen by a veterinarian, and any deworming still on the schedule. Many responsible breeders recommend, or require in their contract, that the buyer have the puppy examined by their own veterinarian within a few days of pickup. Stating this in your listing sets a professional tone and signals that you expect the puppy to hold up to independent examination.

You can also mention, in general terms, the feeding and care instructions the buyer will receive, without turning the listing into a care manual. The point is to show buyers that the puppy leaves with a clear, documented starting point rather than a guess.

Use plain, non-diagnostic language

You are describing a puppy, not diagnosing or guaranteeing its future health. Avoid absolute claims like "100% healthy," "guaranteed no genetic issues," or "will never have hip problems." No one can promise that, and such claims can come back to haunt you. Prefer factual, verifiable statements: which exams were done, what the results were, which vaccinations and dewormings were given on which dates, and that the puppy passed a veterinary exam on a specific date. Encourage the buyer to have their own veterinarian examine the puppy shortly after purchase, which many responsible breeders build into their process anyway.

Common mistakes to avoid

• Claiming a puppy is "fully vaccinated" when only the first shots in the series are done.
• Listing vaccines or dewormings without dates, or from memory instead of records.
• Using vague phrases like "health tested" without naming the specific tests and results.
• Promising absolute outcomes such as "guaranteed healthy for life."
• Describing a health guarantee in the listing that differs from the written contract.
• Hiding a known minor condition instead of disclosing it up front.
• Copying generic health text between litters instead of matching each puppy's records.
• Interpreting or diagnosing findings yourself rather than deferring to a veterinarian.

The bottom line

The strongest health section is simply an accurate one. Write it from the puppy's actual veterinary records, state vaccination and deworming dates precisely, make clear what is still due, name specific health tests and results, disclose known issues openly, and avoid absolute promises about future health. Point buyers to the records and to their own veterinarian for medical decisions. Honesty here does more than protect you legally. It shows buyers that your program is careful, transparent, and worth their trust.
