A baby has been attacked and bitten by a dingo on a remote beach in Western Australia's north.

The girl is not understood to have been badly injured in the incident at Cape Leveque, 200km north of Broome.

The attack comes nearly 36 years after Azaria Chamberlain was killed by a dingo in Uluru in a case that attracted the attention of the nation, after her mother Lindy was convicted of murder and jailed but released after three years when that decision was overturned.

The two-year-old girl in the latest incident is understood to have been bitten through her nappy while her family was having a picnic on the beach.

The girl's alarmed parents chased the dingo away after the Friday night attack that broke the child's skin but did not draw blood, a spokesman for wilderness camp Kooljaman at Cape Leveque told AAP, adding it was distressing for staff.

The girl's mother, Christine Dwyer, told ABC radio the dingo tried to drag her daughter backwards but "only got six inches".

"She tried to crawl away and was crying, and it just ran back in and grabbed her on the back and buttocks," Ms Dwyer said.

Resort staff had been very helpful, shooing away the dog and taking them to nurses to clean up scratches and puncture wounds, she said.

The Shire of Broome said rangers had located and shot one dingo but were unable to find the one believed to have bitten the baby.
