Over 50 families from a residential building in Chongqing were being driven mad over the past week as a score of dogs kept by a neighbour kept barking at night.

"We cannot sleep for days with such barking at night," they said. "It was actually a barking competition."

Police said they had not been authorized to take the pets away for lack of specific rules. Local media are openly seeking tips to settle the issue.
