What your pet needs to cross into Guernsey.
Do these in order. Miss one and your pet can be held at the border.
- Before you go
Microchip (ISO 11784/11785)
Your pet must be microchipped before, or on the same day as, its rabies vaccination. If the chip goes in after the vaccine, the vaccine must be repeated.
- On or after the microchip
Rabies vaccination
A vet gives an inactivated or recombinant rabies vaccine approved in the country of use. The pet must be at least 12 weeks old.
- At least 22 days after the rabies shot
Wait 21 full days after the primary vaccination
You can enter Great Britain only after at least 21 full days have passed since the first vaccination (or the last dose of the primary course). Day 1 is the day after vaccination.
- Still valid the day you arrive
Rabies vaccine still valid on arrival
Your pet's rabies vaccine must still be valid on the day you cross. Check the 'valid until' date on the vaccination record and book a booster before it runs out.
- Before you go
Pet passport, AHC or GB pet health certificate
From a Part 1 country: a valid pet passport. Alternatively an AHC issued in GB, the Channel Islands or IoM (valid up to 4 months after issue). From Part 2 or unlisted countries (or Part 1 countries that do not issue passports): a Great Britain pet health certificate.
- Within 10 days before you arrive
Sign the non-commercial declaration
Complete the declaration that you will not sell or transfer ownership of the pet. If someone else travels with the pet, you must authorise them in writing and the pet must travel within 5 days of you.
- 1 to 5 days before you arrive
Tapeworm treatment by a vet (dogs only) (dogs only)
A vet treats your dog with praziquantel (or equivalent) no less than 24 hours and no more than 120 hours (5 days) before you arrive in Great Britain, and records product, date and time.
- At least 24 hours before you arrive
Animal Import Notification (24 h ahead)
Pre-notify the States Veterinary Officers in writing at least 24 hours before the pet arrives.
