Sniffer dogs helped keep Hangzhou G20 Summit secure

Seven police sniffer dogs and their handlers, fresh from a successful security mission at the G20 Leaders Summit early this month in Hangzhou, Zhejiang province, were welcomed at Harbin Taiping International Airport in Heilongjiang province recently.

"As early as March, we began to train and select sniffer dogs for the summit from more than 200 police dogs at our training base," said Qi Ming, director of the dog training facility of the Heilongjiang provincial border defense troops in Harbin.

After four months of training and rounds of internal selection, seven dogs passed the strict examination of the Ministry of Public Security and joined the mission to intercept explosives during the summit, Qi said.
