A puppy's prevention dates are easy to lose because they arrive from different moments: a dose given by the breeder or rescue, one given at her first veterinary visit, and the next one due at home while you are still learning her routine. One log, kept beside her vaccine card, stops those dates from scattering across receipts, boxes, and memory.
The Fields to Log Every Time
Record the same set for every entry: product given, date given, next date due, and who gave it.
Describe the product as the product her veterinarian supplied, in the veterinarian's own terms, without relying on packaging you may throw away. Date given is the day the dose was actually given, not the day it was bought or planned. Next date due is written at the same moment, taken from her veterinarian's plan and the product's schedule as the veterinarian states them, so a future dose is never reconstructed later by counting forward from a half-remembered start.
Who gave it matters more in a busy household than it first appears. A named giver prevents both a missed dose and an accidental double dose, because the next person can see that the puppy was already treated and by whom. If a dose was refused, spat out, or only partly taken, note that beside the entry and ask the veterinarian how to handle it rather than quietly repeating it on your own judgment.
Intervals Belong to the Veterinarian's Plan
Use the log to record dates, never to set doses or fixed intervals yourself, because the right timing for her depends on her age, weight, health, and the specific product her veterinarian supplied. Early puppy prevention is typically frequent, with doses coming closer together than they will in adult life, and the exact spacing is part of the plan her veterinarian lays out at her early visits.
That is why the next date due comes from the veterinarian each time rather than from habit. A product change, a weight change, or a missed date can all shift what comes next, and a quick call to the practice resets the schedule more safely than a guess at home. Write the revised due date into the log as soon as you hear it, and check the plan back with the veterinarian whenever the written plan and the product in your hand do not match.
Keeping It Beside the Vaccine Card
Store the prevention log and her vaccine card together, in the same place, every time. Vaccination appointments and prevention doses often travel together in puppyhood, so a veterinarian reviewing one record should be able to see the other without a search. A combined view also helps a sitter, a boarding facility later on, or a new practice understand what she has had and what is coming due.
Review the log at each veterinary visit and whenever you book boarding, training classes, or travel. Bring it rather than summarizing from memory, because the exact product and dates are the details a professional needs and the details memory blurs first. Update it the day a dose is given, not at the next appointment, while the giver and the due date are both still certain.
Add a simple reminder rhythm at home as well, such as checking the due column whenever her vaccine card comes out, so a date approaching during a busy week is seen early rather than discovered late. KinsLe's Pet Passport record pairs prevention entries with her vaccine card, making a missed or doubled dose far easier to spot.
