"The sheer ferociousness of the attack was indescribable. These are not dogs, they are killers," Mr Cordenos said.
"They took me down like I was nothing.
"What happened if I was a pregnant lady holding the hand of a two-year-old child?"
An investigation has been launched by Douglas Shire Council with the incident alleged to have occurred at 6pm on Saturday.
Mr Cordenos and his partner Suzie - who own a holiday house at Wonga Beach - were walking their dog Khaleesi when two large pig dogs sprinted towards them.
"It happened in a matter of moments, it was like watching a movie," he said.
