A Kāpiti woman who found one of her beloved pet sheep mauled to death and another injured (pictured) says the experience has "shattered her peaceful rural existence."

It was a less-than-ideal start to the holiday season for Gail Inglis after finding two of her much-loved pet sheep mauled on her Kāpiti Coast property.

The incident, which occurred on Sunday in Peka Peka, left one sheep in such a dire state that he had to be put down.

Inglis discovered what had happened at around 7.30am when she went out to check all her animals were settled for the evening.

"There was blood everywhere, ears ripped, a tail severed. It was awful."

SUPPLIED Inglis says Rojo the alpaca likely chased the dog off before any further damage could be done.

Mumma, another sheep, fared slightly better in the dog attack.

"She is old but chases dogs [but] I'm not sure that she will survive her injuries. She has given up eating and is mostly lying down."

Some credit went to Rojo, an alpaca Inglis suspected had helped chase the dog away before it could do any further damage.

"He saved the flock."

Initially, Inglis had little luck tracking down the culprit but suspected it was out-of-towners. Her hunch turned out to be right.

"My daughter found the dog [who was] worrying the sheep, a fluffy spoodle type staying two properties from me for the holidays."

After being informed of what had happened the owners had offered Inglis compensation for the harm caused but she said it did little to ease her frayed nerves.

SUPPLIED Fortunately the canine intruder wasn't able to sink its teeth into the entire flock.

"No money can mend the damage done to me and my pets. [It's] shattered our peaceful rural existence.

"I'm terrified and so are my flock."

She hopes her experience would encourage dog owners to be more responsible and not let their dogs roam freely.
