A puppy arrives with a bundle of paperwork that looks like admin and turns out to be biography: who bred or rescued him, what a vet has already checked, which vaccinations he has had, and what his first weeks looked like. Saving the right pieces — in their original, dated form — means his history can be proved to any vet, boarder, or future keeper instead of reconstructed from your memory of a busy collection day.
Identity and Status Papers Come First
At the front of the file go the documents that establish who he is and what has been done: microchip registration confirmation in your name, the vaccination record with products and dates, and the spay or neuter certificate or a clinic letter confirming the operation. If neutering happens later, add that certificate the week it is issued and update the registrations that track his status — the chip record, your veterinary file, insurer, and any daycare or boarding file that lists him as entire. Facilities ask for these papers by name, and a clinic-issued original carries dates and a professional source that your word alone cannot.
The Breeder or Rescue Record of His Start
Keep the contract or adoption agreement itself, not just the receipt: it records the parties, the date, and any conditions agreed about his care or return. File the health papers that came with him — parental health test results where the breeder supplied them, the rescue's intake and treatment notes where relevant, and his first vet check report. Worming history belongs here too, with products and dates, because your own vet will continue that schedule and needs to know where it stands. Training certificates, with the cues he learned written on them, round out the picture of the puppy you actually collected.
Add the Working Notes Other Carers Leave
Ask groomers and trainers to write down the practical details they discover: skin or ear findings at a groom, how he handles being lifted or having paws touched, and the exact cue words he responds to. That working record is gold for the next person who handles him, and it is the part of a file owners most often forget to ask for. Add your own dated notes on diet, weight, and any health events as they happen, so the breeder paperwork grows into a living file rather than a snapshot of his first eight weeks.
A File That Can Change Hands Complete
If he is ever rehomed, this file changes hands with him, alongside a proper chip transfer, so the new keeper starts with a complete history instead of a blank page. In KinsLe, Pet Passport gathers the contract, health papers, and certificates into a single packet, so nothing essential is hunted for when a visit, trip, or stay comes up.
