A child has been taken to hospital after being bitten by on the face by the family dog.
The two-year-old was on the verandah of the house in Sawtell in northern NSW when the dog attacked, causing cuts near her eye and cheek.
NSW Ambulance paramedics treated the girl at the scene.
She was then taken to Coffs Harbour Health Campus with non-life threatening injuries.
According to Detective Inspector Darren Jameson, the pet is believed to be a family dog and familiar with the child.
"It is a dog that has been at the house for some time," he said.
"It's not a young dog, it's an old dog."
NSW Police and council officers are now investigating the matter.
This is the fourth serious dog attack of a young child in less than a week.
Experts are advising dog owners to train their pets to ensure the safety of children.
