I am not going to spoil Dogs adventures by giving away all his secrets, BUT.
This kinda goes with what the Brits think of us but is what the US customs thinks of Vegemite. Seems Dog had his sweety try and smuggle several tubes of caustic poison Vegemite, hidden inside ladies under garments thinking American customs would be polite and not look. They did, found it, took it away , threatened to send the poor lady back to Australia and hunt down the Dog. She gave up some other poor Aussy and was able to enter the Republic of Texas with out further ado.
They are safely hidden away from further harassment by the Federal customs folks courtesy of the Texans for equatable treatment of foreigners. I am sure when he calms down from the seizure of his bootleg hair growing compound he with post the rest of the story.
