Overseas Shipping ???

I was looking online for where i would acquire the application, or certificate for US Ag health certificate, to ship out of the country. I keep finding lots of stuff pertaining to the issue, but not quite what I need.

I've got two vets that are certified to do this for me, but both say i need to get the certificate, and bring it in with the animal to get it done. I'm just not finding it.

Any helpful links or info would be greatly appreciated. A shove in the right direction so to speak.

Thanks in advance for any help.
