The folder that goes home with a puppy is read twice: once on the first evening, quickly, and once much later, carefully, by a veterinarian, a new owner, or someone trying to work out what was agreed — and it is that second reading it has to be written for.
The most important first
- Every document in the pack does one of three jobs: it identifies the dog, it records a fact, or it records a promise. Knowing which is which tells you how carefully to write it.
- The Royal Kennel Club lists the core paperwork a buyer should receive: a signed contract of sale, the registration certificate if the dog is advertised as registered, the pedigree, the parents’ health certificates, microchip details, and vaccination and deworming records.
- In the US, the American Kennel Club tells buyers that a dog represented as AKC-registrable comes with an AKC Dog Registration Application filled out by the seller — and that if it is not available at delivery, they should wait before paying and taking the puppy home.
- Paperwork that genuinely cannot be ready on the day should be confirmed in writing, with what will follow and roughly when.
- Keep a copy of everything you hand over. The pack is also your own record of what you said.
Identity: making sure every document is about the same dog
The first job of the pack is to tie every other document to one animal. A puppy’s collar color, pet name and position in the litter mean nothing six months later; its microchip number does. Put the chip number, date of birth, sex, color and parents on a cover sheet and on every page that makes a statement about the individual — the veterinary summary, the vaccination record, the contract, the receipt.
The chip itself carries legal duties in some places. In the UK, all dogs must be microchipped and registered on a database by the time they are eight weeks old, a keeper can be fined up to £500 if their dog is not, and new owners are told to ask for proof that a microchip has been fitted and to make sure the details are updated. The practical point for you is to hand over, in writing, the chip number, the database it is registered on, and exactly what the buyer has to do to become the recorded keeper. The registration side is covered in vet checks, microchipping and registration.
Records: facts the next person will rely on
Most of the pack is records, and a record is only useful if it is specific. A vaccination entry needs the product (brand), date, veterinarian and next due date — the Royal Kennel Club asks for the brand and the next booster date — and it is good practice to add the batch number from the vial sticker; a deworming entry needs the product, active ingredient and dates; a veterinary check the date, the practice and the findings in full, including the minor ones. The Royal Kennel Club also recommends including the puppy’s weight chart, which gives a new veterinarian a growth curve rather than a single number. The detail of what to record is in the pre-sale health checklist.
Screening results for the parents belong here as copies of the certificates or database entries, not as a summary line. The buyer may need them years later, when a condition appears and a specialist asks what was known — and a certificate settles a question that a sentence cannot.
Behavioral information is a record too. The completed socialization checklist and a short note on what this puppy finds easy and what it finds hard are among the most useful things you can pass on, because they cannot be reconstructed by anyone else. Write them as observations — “recovers within a minute from sudden noise” — rather than predictions.
Promises: the documents that bind you
The contract, the receipt, the insurance cover note and any registration restriction record commitments rather than facts, and they are where precision matters most. The contract should arrive in the pack already read, because it was sent ahead; the copy in the folder is the signed one. The receipt shows every payment and the balance as settled. The cover note shows when free insurance starts and, just as important, when it ends — see insurance and liability.
Registration papers deserve particular care because they are where buyer expectations and breeder intentions most often diverge. If the puppy is registered with a restriction or endorsement, the pack should say so in plain words and include the buyer’s signed acknowledgment; if papers are to follow, a written line should say what, from whom, and roughly when. The American Kennel Club’s advice to buyers is blunt: obtain the registration application at pickup, and if it is not available, do not pay and take the puppy until it is. Being ready on the day is simply easier than explaining why you are not. The underlying arrangements are in guardian homes, breeding rights and co-ownership.
In practice
Fourteen months after a sale, a buyer’s veterinarian asks for the parents’ eye test results before a referral. The buyer finds a line in the puppy’s folder saying “both parents fully health tested” and nothing else. The breeder has the certificates but has since moved house, and it takes three weeks to find them. From the next litter, every folder carries copies of each parent’s screening certificates, and the breeder keeps a scanned set in the litter’s digital record.
(Illustrative, composite scenario.)
Guidance: what helps rather than what records
The rest of the pack is advice, and it is the part buyers read first: feeding plan, first-night plan, house-training routine, what to continue practicing, when to book the first veterinary appointment. Write it short. A thirty-page booklet produced once and printed for every litter is less useful than four pages written for this puppy, with its current routine, and pointers to where the longer explanations live. The substance belongs in educating your puppy buyers and the first journey and the first days at home.
Keep clinical content out of the advice section. Continuing deworming and vaccination are dates and products, followed by a line asking the owner to confirm the schedule with their own veterinarian — not a schedule you invent for them.
Handing it over, and keeping your copy
Walk through the folder with the buyer rather than handing it over closed. In England, the statutory guidance for licensed pet sellers requires a puppy contract and information pack to be provided at the point of sale. For licensed dog breeders, the breeding guidance requires buyers to be told the puppy’s age, sex and veterinary record, requires each puppy to be microchipped and registered to the breeder before sale, and treats a puppy contract with health, vaccination and socialization warranties as a higher standard. Either is a useful standard wherever you are: the buyer should leave knowing what is in the pack. Give them a digital copy as well, since paper folders get lost in house moves.
Kennel clubs in other countries set similar expectations. Dogs Australia requires members to give buyers a vaccination certificate signed by a veterinarian, microchip verification and transfer details, responsible-ownership information, and a receipt that states whether the dog is on the main or limited register. The Canadian Kennel Club’s code asks for a written sale agreement, dated and signed by both parties, that includes the dog’s identification number, plus copies of registration papers, any non-breeding agreement, guarantees and health and vaccination records.
Then keep your own copy — every contract, receipt and record, filed with the litter’s records. You will need it when a buyer calls in two years, when a health question comes back from a veterinarian, and when you evaluate the litter as a whole. Remember too that the file contains the buyer’s personal details: store it somewhere secure and keep it only as long as you have a reason to.
Work on it
A few minutes here will teach you more than re-reading the article.
Ask yourself
- For each document in my last puppy pack, could I say whether it records an identity, a fact or a promise?
- Is there anything in my standard pack that is really a prediction dressed up as a record?
- If a veterinarian asked me today for the screening certificates of a dog I sold three years ago, how long would it take me to find them?
Find out & check
- Find out what your registry issues to the buyer at the point of sale, and what your jurisdiction requires to be handed over when a puppy is sold.
Do one thing
- Put a cover sheet with the microchip number at the front of every puppy folder for your next litter, and repeat the number on each page that describes that puppy.
