Do pets need a passport, or equivalent, to move to any other country?

They need veterinary certificates and proof of vaccinations. And even then they may be quarantined for as much as six months.

Hawaii can quarantine pets for 120 days if they don’t have complete recent vaccinations. The UK has similar requirements, although there are pet passports that allow entry from approved countries.

Not if you smuggle them.

I don’t think that they need a passport; however, they must have a health certificate from their vet guaranteeing that they are up to date on their shots & healthy Depending on the country, they can also be quarantined up to 180 days. Whatever you do, don’t think you can sneak them into a country. Johnny Depp tried that & he almost lost his furbaby!!!
