What is a puppy checklist from a breeder or shelter?

Vaccination dates and product names, worming treatment history, microchip number and registration status, a feeding guide with the current food brand and amounts, and any relevant health testing results for the puppy's parents are common inclusions from a responsible source.

If a breeder or shelter does not proactively offer this information, asking directly for vaccination and worming records at minimum is reasonable, since you will need this documentation for your first vet visit regardless.

Keep everything together in one folder or a digital scan from the very first day, since scattered receipts and certificates are much harder to track down later, especially when a boarding kennel, groomer, or new vet asks for proof of vaccination on short notice.

A written diet sheet is worth more attention than it might first seem, since switching food abruptly on day one, even to a higher quality brand, often causes stomach upset. Follow the current feeding amounts and brand for at least a week, mixing in any new food gradually if you plan to change it.

If health screening results for the parents were provided, keep a note of what was tested and the results, since this becomes useful background information at future vet visits, particularly if your puppy's breed is known to be prone to certain inherited conditions worth monitoring over its life. A complete folder also makes any future insurance claim considerably easier to process.
