Dog owners are being reminded of the law and to report sheep attacks after several ewes have been killed in recent months.
PCSO Rhys Evans said many incidents are going unreported to police and farmers, resulting in unnecessary suffering and death of livestock.
A number of these incidents have taken place in the Eryri mountain range.
The latest attack was reported on Saturday 12 September on Brithdir land near Llanberis, which resulted in the death of a Scotch cross ewe.
The farmer reported it was the third attack within three months, resulting in three sheep being killed by dogs.
PCSO Rhys Evans said: “Any such attack needs to be reported immediately to the police or the farmer, in order that the animal can be treated to avoid unnecessary suffering.
“Sheep will hide for a long time following a chase which is why the farmer needs to get there as soon as possible.
“When sheep are spread out over a vast are, they’re often not checked for days or weeks at a time, which is why it is important that any attacks are reported promptly.”
PCSO Evans is urging anyone walking around livestock in the countryside to keep their dogs on leads and to keep close control as per the Dogs (Protection of Livestock Act) Amendment 2025.
“Allowing a dog to chase livestock can cause significant stress, fear and injury – and it is a criminal offence,” he added.
“A dog’s owner is the only person who can prevent an attack from happening, and you may have to pay the ultimate price if you cannot control your animal.
“Responsible dog ownership is key in tackling these awful incidents.”
