Access to the house was at the back of the property through a wooden fenced area. No signs warned of the presence of dogs.
As the officer approached the house, the dogs lunged at her and attacked, jumping towards her face and trying to bite her leg.
She tried to fend them off and managed to get to the house and, after banging on the door, was admitted by Keirin Tutty who, after apologising, told her she should not have gone to the back of the house.
On leaving the property, the officer contacted another council staff member who took her to the emergency department.
Charged under the Dog Control Act, Keirin Robert Tutty, 44, and Dylan Robert Tutty, 23, pleaded guilty by letter to three charges.
Each faced a single charge of owning a dog that attacked a person.
Dylan Tutty was also charged with failing to keep a dog under control.
In the Dunedin District Court last week, Judge Emma Smith convicted and fined the defendants $600 each and ordered court costs of $130, on the attack offence. Dylan Tutty was fined $500 and ordered to pay court costs $130, on the other charge against him.
Council prosecutor Eleanor Bunt said both dogs had now been euthanised.
