Pets are permitted to visit Anguilla. There are some details and paperwork that needs to be taken care of before you arrive.
The Agriculture Dept. will send you an Import Permit form. Have your veterinarian fill out this form. You must supply a health certificate from your veterinarian dated 10 days or less before your arrival on Anguilla. The health certificate must indicate when last your pet had a rabies shot .
Important Note: Anguilla does not honor the every two years vaccination approved in the states, you must have a rabies vaccination within a year for Anguilla regulations.
