Ive shipped my Lhasa Apso many places. Even when we moved from Germany to Italy (thank you US ARMY) he did just fine with a very fluffy blanket i mean sooo comfy you want to steal it. He also did great not drinking anything for 5 hours before the flight and right before he got on he went outside for a bathroom break. Just a big fluffy blanket will do fine unless you dog has a very very special toy he always has with him. My dog also was shipped back to the states several times. Make sure the blanket smells like his favorate onwer.
