The youngster was attacked by a two-year-old Doberman at home in Sheffield on October 25.
The pet was lying out on the sofa when she went to try and kiss it, but the animal reacted and mauled her head.
Horrific photos of the little girl from after the attack show the side of her face and ears covered in blood, and she was taken to hospital where she required surgery.
The dog responsible for causing injury to the child was seized by South Yorkshire Police officers and will be put to sleep.
Sergeant Matt Duffy said: ‘We are continuing to see children bitten by dogs across South Yorkshire.
‘We are working hard to reduce the risk from dangerous dogs to our communities, but we need your help.
‘You know your family, you know your dog.
‘As we approach a time of year where things are slightly different, people are in costumes and you may have more visitors to your home, please take action.
‘Also, please remember that when a dog has been exposed to stress or anxiety, it may take a few days for the effects to end.
‘It is important you are vigilant and provide your dog with a safe space.’
