We have friends who cruised in the Eastern Caribbean with a wonderful standard poodle and they found it to be very difficult and very costly. I don't remember the details but there were some countries that did not allow dog's to enter without extended isolation in kennels. In other country's a vet had to come to the boat to see the dock at a cost of $100 to $200. For one winter's cruising they had spent something like $2000 on fees related to the dog.
Good luck, don't know if Noonsite has dog info? Have you checked there?
Back in the water in Grenada - with new main and #2 and cockpit canvas (Santa came early). Will spend the winter and early spring in the Caribbean and then head to Bermuda and the northeast US. Still trying to decide if we will bring the boat to Canada, either in 2015 or 2016.
