Police are yet to decide whether to destroy the two dogs that fatally mauled meter reader Kane Minion at a property south of Brisbane on Saturday.
Mr Minion, 42, was attacked while trying to read an electrical meter at a property on Ison Road in the Logan suburb of Greenbank.
The owners of the property were not at home at the time.
Mr Minion was found by emergency services in a critical condition but died at the scene.
Police found three dogs at the property and two of them — a bandog bullmastiff cross and a Rhodesian ridgeback cross — were impounded by Logan City Council animal control officers.
A council spokesperson confirmed on Monday the dogs were in council's pound.
"An investigation is still underway and council is cooperating with Workplace Health and Safety and Queensland police," the spokesperson said.
Dangerous and restricted dogs are managed by local government.
A decision on whether to put the dogs down will be made after investigations are complete.
But Logan council was not aware of any previous problems with dogs at the Ison Road property, the spokesperson said.
"They had not come to our attention, no."
Energex urges people with dogs to register the animals via their website and the ABC understands the dogs at the Ison Road property had been registered by this process.
Energex urges dog owners to ensure their dogs are "visibly sighted as restrained" when meter readers visit the property.
Property owners can also register to receive SMS alerts 24 hours before their meter is due to be read, but it is not known if the dog owners had done so.
Mr Minion worked for Skilltech, a subsidiary of Downer Group, which was contracted by Energex for meter reading.
Electrical Trades Union Queensland secretary Peter Ong told ABC Radio Brisbane the union had now joined the investigation.
"It's an absolute tragedy, I can't even begin to imagine what the family is going through especially this close to Christmas, but at any time," Mr Ong said.
Mr Ong said meter readers faced many hazards, not just dogs and other animals, but often abuse, threats from customers and other issues.
"We've faced these issues over a number of years, and we've done what we can, put measures in place to try and address it," he said.
"There are times where our members won't go in and read meters if they can obviously see the hazards, being dogs or any other hazards – overgrown shrubs and things that might have snakes, that sort of stuff, but mostly dogs.
"In some instances our members carry protection in the form of pepper spray and mace for dog attacks, but generally we try and avoid them altogether.
A Downer spokesperson said Skilltech followed a "zero harm safety process" in relation to dogs at properties, and that meter readers were advised not to enter if it was not possible to confirm a dog was restrained.
"Kane has worked with Downer’s Skilltech metering business for more than seven years, and was a popular member of the team," the spokesperson said.
"Downer extends our deepest sympathies to Kane’s family, and we will support them through this incredibly difficult time.
"Details of the incident are still being examined, and a police investigation is underway."
