Logan City Council is investigating a dog attack at Jimboomba on February 19, which left a seven-year-old girl needing surgery and the animal being put down by its owner.
A Logan City Council spokesman said an investigation began after police reported the incident.
"When council arrived at the property shortly after the report, one dog had been euthanised by its owner," he said.
Wayde Matthews, the victim's father, said his daughter went to hospital for treatment and was again admitted on February 21.
"On the Friday (February 22), she received surgery to two of her bite wounds."
Mr Matthews said his daughter had been walking the 200 metres home from the school bus stop but she only made it halfway before she was attacked by a pack of pig hunting dogs.
"My daughter was alone," he said. "Her screams alerted the owner who came to her aid.
"A neighbour in the street also heard the altercation and assumed it was dogs fighting until she heard my daughter screaming and came to help.
"My oldest daughter got off the bus minutes later to witness the ending.
"I'm eternally grateful to the wonderful ladies that came to help."
Mr Matthews said five dogs were involved in the attack and his daughter had identified two of them.
One had been put down and another removed from the property by the owner.
He said there were an excessive number of dogs living on the acreage but council had told him they did not have grounds to remove the remaining dogs.
Mr Matthews said he feared the dogs were capable of far worse damage.
The spokesman said council had been in contact with all parties.
"Under state legislation, council has powers to act in matters where a dog may be deemed dangerous and menacing.
"Council is responsibly considering all options provided within that legislation as part of our investigation."
He said the incident was a timely reminder that all dogs, regardless of breed or age, could injure a person or another animal.
Most attacks occurred in public places like footpaths and parks, after dogs escaped from their yards or were not under control.
Preventing a dog attack was the pet owner's responsibility and in particular to ensure their dogs cannot escape their yard.
