Passed my Global Entry "interview", so I should be legit in 72 hours.
CBP guy saw Tank on my phone and we had a long discussion about CBP working dogs. He said they had two GSDs. CBP K9 Ginna is a drug detector dog (first pic) and CBP K9 Nicky (second pic) is a currency detector dog. Currency detector dogs are trained to sniff out money in excess of a specific quantity (seriously - for CBP that's anything over $10k)
Apparently the dog who sniffs out food is a beagle 😂
