A Victorian teenager says her sleeping bag was torn off by a dingo while she was camping in the Northern Territory.

Rebecca Robinson, 13, of Benalla in central Victoria, was sleeping outside a tent in the Kakadu National Park on Sunday when she woke to find a dingo nearby.

Her mother Kate Robinson says it is the fourth such incident in the area this year.

"She's heard a ripping sound and the sleeping bag's been ripped," she said.

"She has woken up and sat up and the dingo is there at the sleeping bag trying to pull the sleeping bag away.

"So she's yelled at it and it's run off."

She says she can understand how dingo attacks have happened in the past.

"You can totally understand how something like that (Azaria Chamberlain) can happen," she said.

"You can see it happening again if something is not done with them."

Parks Australia says Kakadu National Park rangers have caught and killed three wild dogs today, and are continuing to patrol the area.
