Just talk with the vet & they will recommend something.
This actually refers to pets put in cargo. Mike and I have flown with our cats to Europe and back and all over the States.Sedating a pet when flying is dangerous and is one of the worst things you can do for the safety of your pet.Sedatives can interfere with regular breathing and other bodily responses, and pets may react differently and unexpectedly to medications when they are in the air. In fact, most airlines will not fly a sedated pet, as it can be a cause of animal death during air transport.
