Norwegian government-owned alcoholic beverage retailer, Vinmonopolet, is using a Springer Spaniel named Tutta as a weapon against the use of fake identification cards .
Tutta's sensitive nose is able to detect if underage teenagers are using someone else's, or fake ID when trying to buy alcohol.
People who are nervous will secrete substances into the skin which Tutta can detect. Tutta now visits various outlets to sniff out the potential use of fake ID cards.
Every year Vinmonopolet reject 10,000 woud-be customers because they are not old enough, or lack valid identification. Campaign "Id hund.no" highlights what young people risk if they use someone else's, or fake ID.
