Health Certificate for Cruising Dog

[Jan B]

My vet in Minnesota gave me a health certificate today after examining my dog, however she said it was a "domestic" certificate and could not give me an "international" certificate unless I had an address I am visiting outside the states. The form is for both US and international. The only thing that appears to be missing is a box where USDA Seal or stamp and the signature of a USDA veterinarian is required. I suspect my vet could have signed this but since I didn't have an address where I will be visiting, she wouldn't. Has anyone else run into this problem? We will be in the Caribbean beginning in the late fall, but will avoid destinations where we know it will be a problem bringing our dog in. Any suggestions on how to get an international health certificate or information on whether or not it is needed would be appreciated. We won't have an address as we won't be staying any place for very long. I suppose I could make one up, but then maybe it would only be good if I visited that country.
