Since dog attacks on their stock began they have erected a tall fence along their Tongatu Rd boundary, which includes a buried metal barrier for extra protection on their border.
The latest dog attack came to light after Mr Angliss was summoned to his front gate at 7.30am on Friday by a man looking for two pig dogs missing from a neighbouring property.
Mr Angliss let his dogs out of the house and soon after saw them chasing two large dogs toward a neighbour's place. His distressed wife then told him their Alpaca named Peppermint had been "ripped to pieces".
He confronted the owner of the two pig dogs at the neighbouring property, seeking $1000 compensation for the dead alpaca or permission to shoot the dogs.
The man left with his dogs after Mr Angliss agreed to give him two weeks to "put things right".
A woman living at the property told the Advocate the man was a visitor whom her partner had invited to stay last Thursday night.
Mr Angliss then went to see Peppermint and was horrified to find the alpaca part-eaten.
Angry, he resolved to get the dogs' owner prosecuted and try to get dogs banned from the neighbour's property. He called Environmental Northland. The two dogs found at Maungakaramea were impounded on Monday, although he didn't want the dogs destroyed as "it's the owner to blame, not them". The dogs' owner could not be contacted for comment.
