Eagle Beach Boy - i responded to your question in detail on this subject at the
www.aruba-bb.com site but I will also respond here for information purposes for others.
I have taken my dog Annie to Aruba with me several times. There is no quarantine - she has been to Aruba about 10 times over the past 3 or 4 years.
First, you need a health certificate from a veterinarian within 5 days of travel along with a Rabies vaccine certificate. US customs also requires that your dog have an identification chip.
To travel in the passenger compartment, the dog cannot weigh more than 20 pounds and must fit inside an airline aprroved carrier - a Sherpa carrier is approved by most airlines and can be purchased on line. The dog must be able to stand up and turn around in the carrier.
You must book your dogs passage ahead of time to insure space is available - American Airlines does not allow more than 5 dogs in the cabin, jet blue only allows 4. I don't know about the other airlines but you can go on their websites and do a search "traveling with pets"
I have never had a problem bringing Annie into Aruba or back into the States. You do have to declare that you have a dog at Aruba customs when you arrive - they check the paperwork. And then when you leave, you have to inform US customs and they check the paperwork closely.
I have also brought puppies back from Aruba for adoption and have the vets there complete the health certificate - these pups do not have identification chips.
Our little dog, Annie, travels well - she is used to it so we do not medicate her. She knows that she can take a nap, get some treats, and then she is in Aruba and ready for the sun and a run aroud the pool! However, the vets have suggested using Baby Benedryl 5cc per 12 pound dog to help them sleep through the flight if needed. I have done this with some of the pups and it just makes them a little sleepy and makes them less anxious about the plane noise. Any more questions, Private message me....Cheryl
