A little penguin found hurt at Discovery Bay, near Portland, spent six weeks in rehabilitation after being picked up by wildlife rescuers.

Last Sunday, a wallaby had to be euthanised after it was attacked by at least one dog at Logans Beach in Warrnambool.

Wildlife rescuers, assisted by strangers, saved the wallaby from rough surf and took it to a vet.

After the incident, members of the Warrnambool Wildlife Rescue Group urged dog owners to take responsibility for their pets.

The little penguin was nursed back to health at Mosswood Wildlife Rescue and Rehabilitation shelter in Koroit using antibiotics, intensive care and other rehabilitation to help him gain weight.

This week, the bird’s wounds had healed enough to restore waterproofing to his body, which led to his release back into the water.

His carers reported he was happy to see the ocean again.
