"It's a good local event so we made the effort to come along," Mr Morrison said.
The massive canine stands about 180cm tall on his hind legs and eats a kilo of food, or half a dog roll, for dinner alone.
Mr Morrison takes Zeke for 2km to 3km walks every evening as well as taking him to work where people got to know the giant dog.
"I take him with me to work and he hangs his face out the window, people know who we are," Mr Morrison said.
Event manager Alison Curtis said the event was to give back to the dog owners of the Western Bay.
"People always say that you don't get much for their dog's registration and so this is about giving back to both the dogs and the owners," Ms Curtis said.
However, the key message from the event was to encourage people to register, microchip, and desex their dog when appropriate.
