Pet vaccinations lapsed? What it means and what to do

Vaccination cards are the quietest expiry date in the household: nothing beeps, the pet looks fine, and the lapse only surfaces at the worst moments — the cattery desk before a holiday, or the insurance claim after an illness.

What a lapse actually costs

• Protection itself. Immunity wanes; the diseases core vaccines cover (parvovirus and distemper in dogs, flu and enteritis in cats) are exactly the ones that spread fastest and hit hardest.
• The restart. Miss the booster window and some vaccines require redoing the two-dose primary course — more visits, more cost than the booster you missed.
• Boarding and daycare. Kennels and catteries require current records; kennel cough for dogs is often a separate vaccine with its own lead time of days before boarding.
• Insurance. Policies commonly require up-to-date vaccination and can decline claims for preventable diseases. A £40 booster gap can void a £2,000 claim.

Getting back on track

1. 1
   Call the vet with the card in handThey’ll check the dates against the vaccine used and tell you: single booster or restart. Practices see this constantly — no lecture, just a plan.
2. 2
   Book kennel cough separately if boardingIt’s usually not in the core set for dogs and needs time before the stay — ask when booking the appointment.
3. 3
   Fix the system, not just the jabPut the next booster date somewhere shared the day you leave the surgery — with a reminder a month out, so holidays and boarding never collide with an overdue card.

In short

Ring the vet — booster or restart is their call, and it’s a routine one. Then give the next due date a shared home, because this is the one renewal where the deadline never announces itself.
