Singapore sets its own requirements for bringing in dogs and cats. From any departure country your pet needs microchip, rabies vaccination, parasite treatment, import permit, veterinary health certificate and additional vaccination. What is needed on top — rabies antibody titre test — depends on the country you fly from. The rules are the same for dogs and cats.
There is no quarantine if the rule's conditions are met — otherwise the pet is held. Pets may not enter through just any airport: there is only one designated point. Order matters more than the list: the microchip goes in before the rabies vaccination, or the vaccination does not count. 13 carriers in our directory fly direct to Singapore, and their pet conditions differ.
