Workmates of a Queensland man whose six-year-old daughter was scalped in a horrific dog attack last week have set up a fund to meet the girl's mounting medical bills.

Isabella King lost the top of her head when a dog grasped hold of her hair and tore it from the roots as she played in a neighbour's yard in Cape York last Thursday.

The mixed-breed dog, used for pig hunting in the far north township of Weipa, also bit her shoulder to the bone, local media reported.

She was rushed to the Weipa Hospital but has since been transferred to the Royal Brisbane Women's and Children's Hospital for surgery to reattach 70 per cent of her scalp, which was torn off in two pieces.

Hospital officials have refused to discuss her condition with the media, but in an interview with , Isabella's father, Asa, said 50 per cent of the reattached tissue had died, forcing surgeons to use skin grafts.
