An international move turns routine prevention into paperwork with consequences: a flea treatment nobody wrote down, or a worming date that lapsed during the packing weeks, can surface at a border or a carrier check-in desk where there is no time left to fix it. Treat the treatment record as travel documentation from the start of the move, not as housekeeping to catch up on afterwards, and check it against two audiences at once — the destination country and the airline or ferry company carrying her.
What the record has to show
For each type of prevention, the record needs three things legible together: what was given, the date it was given, and the date the next one falls due. Product names matter here in a way they do not at home, because an official reading the record abroad may need to recognise the product and its active ingredient rather than a nickname you use in the kitchen. Keep the packaging or the receipt until the next treatment replaces it, so any query about a dose can be answered from the box rather than from memory. If she is mid-course on anything, write down where the course stands instead of leaving the new vet in the new country to reconstruct it.
Check the destination's rules early, not at the airport
Requirements differ by country and by carrier, and both can ask for more than your home routine involves. Some destinations want treatments given within a set window before travel, some want them recorded by a veterinarian rather than at home, and carriers add their own paperwork checks on top. Ask early — weeks ahead, while a missed window can still be re-planned — and ask the practice that will sign any travel documents, because they see these forms daily and know which entries get queried. Book any needed appointment with slack in it: a treatment given too close to departure to count is a problem you want to discover in the consulting room, not at check-in.
Keeping the dates current while everything changes
A move scrambles the cues a treatment routine normally hangs on. The calendar reminder tied to the old house, the packaging kept in a particular drawer, the appointment rhythm at the old practice — all of it dissolves at once, and due dates slip quietly in the noise. Put each next due date into your calendar the moment it is given, with the product named in the entry, and photograph the record as a back-up you can reach from a phone in another country. When you register with a new practice after arrival, hand over the treatment history at the first visit rather than waiting for something to go wrong, and confirm which of your home products are used locally so the record stays continuous across the border.
Her prevention history deserves the same travelling back-up as her vaccination record, kept where an address change cannot strand it. In KinsLe, that same Pet Passport travels with her, holding the given dates and the due dates together for whichever official or veterinarian asks next.
