The Irish Farmers' Association is calling on the public to report the movements of stray dogs in rural areas, following two recent attacks which have claimed the lives of 60 sheep.
The attacks happened in the Castlerea area of Co Roscommon and at Mountmellick, in Co Laois.
The Roscommon attack happened last weekend.
Gardaí believe that up to seven dogs may have been involved in the attack on a 95-strong flock of in-lamb ewes.
