The sniffer dogs at Chisinau Airport have been working extra hard in recent months, searching for money that might be evidence of Russian meddling in Moldovan politics. Ami, a black retriever, gives every suitcase that rolls in on the baggage claim belts a good sniff on all sides. If she detects cash, she will freeze. Back in May she was doing that a lot. That is when customs officers began finding large amounts of money on passengers arriving via connecting flights from Moscow. People who had never left Moldova before were returning from a few days in Russia with wads of notes.
