The attack occurred at a farmyard in Hestra, southern Sweden, with 21 of the farmers 25 sheep either killed or so close to death that they needed to be put down.
“It’s still shocking, it feels like a nightmare,” farm owner Anders Svensson told Sveriges Radio (SR).
“There are dead sheep and lambs everywhere. They’re floating in the pond… It’s a terrible sight, like a massacre.”
An animal expert at the County Administrative Board (Länsstyrelsen) Linda Andersson has visited the scene and is convinced that a wolf was behind the gruesome attack.
“There is no doubt that it’s a wolf that has attacked the sheep, you can tell by the powerful bites on the necks and the backs of the sheep,” she told SR.
“(The farmers) have reason to be concerned now, the wolf is in the area and it is very likely that it will attack again. That’s usually how it is with wolves.”
Andersson warned that farmers in the area should also inspect their fences to ensure no wolves will be able to get access to their sheep.
