You must get your pet microchipped before, or at the same time as, their rabies vaccination. If you do not, they’ll need to be vaccinated again. Ask your vet how long you must wait before travelling - some rabies vaccinations take longer to work than others. You will have to wait at least 21 full days after the first rabies vaccination (or the last of the first course of rabies vaccinations) is given. Day 1 is the day after the rabies vaccination. ## Source - https://www.gov.uk/bring-pet-to-great-britain/rabies-vaccination-and-boosters Last verified: 2026-09-15. Review by: 2026-12-26.
