Police have arrested the owner of a pack of pig dogs that mauled a jogger in Waikato.
Margit Christensen, 36, of Putaruru, was attacked by eight pig dogs while jogging in rural Arapuni on Monday.
She is in a stable condition at Waikato hospital after undergoing nine hours of surgery.
A 29-year-old woman from Putaruru faces eight charges of owning a dog that caused injury and is to appear in Tokoroa District Court next week.
Ten dogs have been seized from the property - the eight dogs that were involved in the attack have been destroyed.
Police say they are continuing their investigations and more witnesses will be spoken to.
The South Waikato District Council animal control office says the pig dogs destroyed included bull terrier crosses and ridgebacks and were handed over by the owner.
Sven Christensen, the husband of the woman attacked, is calling for all of the dogs on the property to be put down.
Mr Christensen says there needs to be tougher consequences for dog owners who cannot control and manage their animals.
He told Nine to Noon on Tuesday that there are too many dog owners who cannot control their dogs.
Mr Christensen said his wife's injuries are the worst he has ever seen and she is lucky to be alive.
Foetal position saved woman - doctor
John Bonning, an emergency department doctor, told Morning Report Mrs Christensen saved her life by curling into a foetal position and she could have easily died in the attack.
Mrs Christensen told Dr Bonning the attack lasted 15 minutes. He says she will require many skin grafts and several more operations.
Westpac Waikato air ambulance pilot Loren Haisley says she had lacerations to her scalp, legs and arms. He says the injuries are among the worst he has seen is and something he won't forget.
Last year, a teenage was savaged by four pig dogs in Waikato. He was saved by passing motorists during the attack in the township of Waitoa, near Morrinsville.
