Their spokesman, Warwick Stevens from Lavenham Road, said it was the third time they had met with the GDC over the issue.
“Farmers out here are on edge, because most of the attacks have happened between three and four in the morning, so we’re out there at night trying to protect our livelihoods.”
Farmers have shot and killed 16 dogs now since the slaughter began about five weeks ago.
“The council has shot three dogs as well,” Mr Stevens said.
“But the ringleader of the dogs doing this remains unaccounted for.
“The council seized a dog from the same property the ringleader comes from yesterday, the same dog that they released back to the owner after the attacks on Bob Bryson’s sheep five weeks ago.
“We understand the owner of the ringleader moves the dog around to different addresses, and we hope in the interests of the community out here he will see fit to hand the dog over, to surrender it to the council animal control section.
“We know who the owner is, and so does the council,” Mr Stevens said.
“We’re frustrated and angry that it has taken the council five weeks to act on this effectively.
“They told us at our meeting yesterday that they have been more proactive recently, and they promised us they would step up their patrols even more to bring this terrible slaughter to an end.
“The council also promised to support landowners in any legal action they may take against the owner, or owners, of the dogs doing this.
“In the meantime, the owner of the ringleader dog needs to surrender it — now!”
