In a previous Bay of Plenty Times article Western Bay Wildlife Trust chairwoman Julia Graham said even the most friendly of dogs can attack and kill penguins on the beach.
"Many penguins come to shore, just needing a place to park up and rest or moult for a few hours. Then along comes a dog and you're dealing with massive injuries and a dead penguin," she said.
In the past year 24 penguins had been killed in dog attacks that the Western Bay Wildlife Trust knew about.
Recently a penguin was killed by a dog on Papamoa Beach.
The penguin, which they named Kirk, had been blinded after it was bitten through the skull by a dog, with a tooth reaching its right eye.
