The identity and registration papers
A breeder's puppy pack should first establish exactly which puppy you are taking home. Look for the microchip paperwork showing the number implanted in your puppy, and check that the number on the sheet matches the puppy the breeder says it does — a breeder with a litter of similar-looking pups should be happy to scan in front of you. Where the litter is registered with a kennel club or breed registry, the registration document or application should be there, along with the litter's ancestry papers if the litter was sold on that basis.
Also expect the sales paperwork: a receipt or contract naming the puppy, the price arrangements in plain terms, and any conditions the breeder has explained, such as returning the puppy to them if you cannot keep her. If the parents' health test results were part of why you chose this breeder, copies of those certificates belong in the pack too, not just an assurance that testing happened.
The health record for the first weeks of life
Ask for a written record of everything already done to this puppy. That means the dates of worming treatments given since birth, any vaccinations administered with the product details recorded by the vet, and the report of the litter's veterinary health check — the examination each puppy should have had before sale. That report should be specific to your puppy, noting her weight, heart, eyes, bite and any finding the vet flagged, however minor.
Read it at the breeder's table, not in the car. If one puppy in the litter had a heart murmur noted or a hernia mentioned, you need to know whether that note belongs to yours, and what follow-up the vet recommended. Questions asked face to face get answered; questions sent later compete with the breeder's next litter for attention.
Feeding and routine notes in writing
A good pack includes the practical handover: which food the puppy is weaned onto, how much she is currently eating and how often, and a small supply of that food is often provided alongside the paperwork, though the written details matter more. Notes on the routine she knows — where she has been sleeping, how nights have gone, what toilet training stage she has reached — help you keep her world consistent for the first unsettled days.
If feeding information is vague, pin it down before you leave. A puppy moved abruptly onto a different food commonly gets an upset stomach on top of the stress of a new home, and you will not know whether loose stools are diet, stress or illness unless you know exactly what she was eating yesterday.
Do a final sheet-by-sheet check
Lay the pack out and work through it against a simple mental list: identity and chip papers, registration or ancestry papers where applicable, health and vaccination record, parents' health test copies, contract or receipt, feeding notes. Confirm your contact details are written correctly anywhere the breeder or chip registry will use them, since a single wrong digit in a phone number is the kind of error that only surfaces when it matters most.
With that checked bundle in hand, keeping it whole is the next job, and KinsLe's Transferrable Profiles are built for exactly this handover, moving your puppy's profile to you with her history, records and routines carried across rather than retyped from memory.
