Longford IFA Chairman Gavin White is appealing to dog owners to make sure their pets are properly under control at all times.
His appeal comes in the wake of dog attacks on sheep in Roscommon last week, and recent attacks on flocks along the Longford-Cavan border.
While small numbers of sheep may be killed outright in the attacks, there is a huge issue with in-lamb ewes aborting if they have been terrorised by dogs.
The Longford IFA Chairman says there is an onus on every dog owner to make sure their family pet isn't roaming the countryside where they can attack animals.
"Unfortunately these dog attacks are all too common. It doesn't matter what time of year it is, it shouldn't be happening at all. At the moment all dogs are supposed be microchipped and all dogs are supposed be under their owners control. Some sheep, you might not see any damage on them but it upsets them. Most ewes, the very late lambing ones, will be going in lamb now abd te early ones will be starting after Christmas so this is the maximum amount of sheep in lamb that you'll have in Ireland during the season."
