A four-year-old girl has undergone surgery on her "significant injuries" after she was bitten in the face by a dog on Wednesday night.

The child was bitten by a rescued great Dane and the dog's owner decided to put the animal down.

The girl underwent surgery at the Queensland Children's Hospital.

Paramedics were called to a private property in Morayfield, north of Brisbane, just before 7pm and took her to the Mater Children’s Hospital in a stable condition.

Moreton Bay mayor Allan Sutherland said council had last month toughened its stance on unprovoked dog attacks and adopted a zero-tolerance policy.
