While I realize that this is an old post, I thought I would give it an answer. I recently arrived in Dominica with 2 dogs and 1 cat from the US. It was an interesting trip I can tell you.
The requirements to bring animals in are as follows:(I found this on the internet and used it as a guideline. I have added notes in ().
    The animal must be examined by a licensed and accredited Veterinary authority in the exporting country, and a certificate issued indicating the health status of the animal. (Accredited with the USDA, if your in the US)
    The animal must be free from internal and external parasites.
    The animal must be tested and treated for Heart Worms and certified Heart Worm free for export.
    The health records indicating the Immunization Status of the animal must be provided with a current DHLPP+ C Immunization Record or any other endemic diseases of importance.
    Dogs and cats coming from all Countries must be immunized with an approved Rabies Vaccine by an official veterinarian stating type, serial number, date of expiration and date of administration, at least 30 days and not more than one(1) year prior to exportation of animal.
****(This is the important part: This test takes at least 30 days for results. DO NOT Wait until the last minute or you will not get a permit and your animal will go into quarantine)
    A blood sample must be taken from the animal and sent to a reputable Rabies Reference Laboratory to perform the RNATT (Rabies Neutralizing Antibody Titration Test)/FAVN (Fluorescent Antibody Virus Neutralization), and the result must be sent directly to the Veterinary Services prior to issuing an import permit. The test result must show a serum antibody level of at least 0.5 IU/mL
    The test must be done not less than one (1) month after vaccination with an approved Rabies Vaccine. N.B. Please note that the test takes 3-4 weeks or longer before a result can be obtained. Please be guided by this information in relation to your travel plans. Processing and other fees may apply.
    An Import permit will be issued once the requirements are met, and sent to the importer by fax or email.
    Animals and associated documents will be examined on arrival at Port by a Quarantine Inspector who reserves the right to reject or accept the animal based on its condition.
For information on importing live animals other than cats and dogs, contact the Livestock Development Unit of the Division of Agriculture at telephone numbers 1- (767) 266-3827 or 1- (767) 266 3824. E-mail: agrivet4@hotmail.com / forestvet@gmail.com
Keep in mind, it was almost $1000US to bring just one of my animals. That included all of vet, shots, test, airline fee, crate, etc. Since we could not get a same day flight, I also had to find a hotel in Puerto Rico that would except animals and due to the fact that I had three, I had to rent two rooms(only 2 pets per room).Â
I don't regret it though. My babies are happy and enjoying their new life as much as I am.
