A SNARLING police dog cleared about 300 people from an "out-of-control" house party in a matter of seconds.
The Sunshine Coast Dog Squad joined five police units to shut down the Buderim house party on Saturday night.
Neighbours had told police it was out of control.
Almost 200 partygoers had spilled on to the street, and another 100 were inside the Forestwood Dr home when police arrived at 10pm.
It was understood the party had been organised for a "few weeks", but the reason for the celebration was unknown.
The Dog Squad quickly put an end to the celebration and police made no arrests.
Police are now urging parents to talk to their children about the dangers of attending "Facebook parties".
"These parties can turn into large gatherings of minors with no appropriate adult supervision," Community Safety and Crime Prevention co-ordinator Sergeant Cary Coolican said.
"We are asking parents and teenagers alike to use common sense. These parties have no security and we have needed to shut down a number of them due to excessive noise, wilful damage complaints and under-age drinking."
Sgt Coolican said parents and teenagers could register parties with police as a safety precaution.
"For young people, it is certainly a part of growing up, having fun and celebrating special occasions with their friends," she said.
"However, intoxicated guests, gatecrashers, assaults and other criminal offences can ruin the occasion.
"Facebook invitations are fraught with many dangers, so we are appealing for parents to ensure they know where their children are over the weekend."
