Can I Bring My Pet to Guatemala?
Yes, but it requires some effort and shouldn’t be attempted unless you plan on being in Guatemala for a long time. Among other things, you must apply for an Import Permit and have proof of a rabies vaccination. You'll also need to get the endorsement of the Guatemalan Embassy or Consulate.
Pet Travel, the worldwide travel resource for pets, is good website that details the necessary requirements for bringing your pet to Guatemala.
