A savage dog attack on sheep in the Christchurch suburb of Hei Hei has left about 21 animals dead and others injured.
Joshua Olykan said he came home to his parents' Buchanan's Road property yesterday morning to discover 14 animals dead, dying or badly injured.
He said two other neighbouring properties also suffered stock losses, with more than a dozen sheep savaged in a paddock between Gilberthorpes Road and Pound Road.
In total, 21 sheep were killed in the attacks and most of them were in lamb.
He fears further attacks now the dogs, or dog, responsible have a taste for blood.
"We're all pretty shocked by it and we've had to bury the sheep and there's a bit of a clean up job to do now," Mr Olykan said.
"It's a pretty horrific sight to have to deal with on a weekend, or any time.
"The neighbouring home owners are pretty distraught as well."
The Christchurch City Council are investigating and police have been notified.
Mr Olykan said the dogs involved must have returned home covered in blood and someone must know something.
"What we're hoping for is that a dog owner comes forward with their animals and reports themselves to police."
