Sending Dog Back To USA??

Has anyone relocated their pets outside of Angola? I'm going back to the USA for a few months and want to take my dog I have all the forms needed for travel but I'm having a hard time figuring out which airline to book his travel? My own flight is a connecting flight with two different airlines can anyone share what they have done or hear someone else do for this? Please and thank you.

Hi. I transported my 2 cats from Angola sending them by TAP . Maybe Lufthansa also allows. No other airline at that time accepted. It was may 2010.

Go to the terminal of cargo it s almost next to the airport . Find there TAP and in an office next is the broker who does the documents. They are serious as the TAP cargo as the broker. Send them greetings from the man with 2 cats.
