Two "ace" sniffer dogs who have performed sterling service combating drug trafficking in Thailand's Chiang Rai airport have been given their marching orders for urinating on luggage and "sexually harassing" female passengers, the Bangkok Post reports.

Mok and Lai had apparently been "plucked from obscurity" as part of a cunning King Bhumibol Adulyadej plan to use strays as police dogs. They were deployed at said airport close to the border with Laos and Myanmar, but quickly attracted numerous complaints from the public due to their uninhibited behaviour.

Mok's former handler, Police Lieutenant Colonel Jakapop Kamhon, explained: "Both were just as good as foreign dogs trained for use in drug missions. But they were stray dogs, so their manners were worse than those of foreign breeds.

"He [Mok] liked to pee on luggage while searching for drugs inside. He also liked to hold on to women's legs."

Mok and Lai have been reassigned to farm duties, including "herding chickens and pigs", the Bangkok Post confirms. ®
