Several fights then broke out near the club as other police officers arrived.
Two men soon started fighting with Officer Brent Dooley, who was hit in the head by a liquor bottle.
One of the men also choked a police dog who tried to subdue him.
Both officers and the police dog are expected to fully recover.
