In Argentina, the government is using dogs to sniff out US dollars.
As part of a crackdown on tax evasion, money laundering and cash being sent overseas, restrictions are being imposed on foreign currencies, especially the US dollar.
Those restrictions have made the dollar, seen as a refuge from double-digit inflation for many Argentine people, increasingly difficult to find on the streets of the capital.
Those who do possess the US currency are smuggling millions into banks in neighbouring Uruguay.
In an effort to curb that capital flight, the government of Cristina Kirchner, the Argentine president, has employed dogs to sniff out the currency.
