Killer dogs slaughter 38 sheep
Dead animals could 'leave farmers thousands of pounds out of pocket'
Vicious dogs mauled almost 40 sheep to death in two separate attacks over the past 10 days.
The mass slaughter happened on farmland in the Londonderry area.
The carcasses of 38 sheep were found in fields in the Whitehouse Road and Groarty Road areas of Derry after the two killing sprees.
Farmer Patrick McNichol, who has lost part of his flock in the same way in the past, said discovering savaged sheep was a sickening thing for any man in his position to experience.
He added: "This is a terrible thing for any sheep farmer and these particular attacks could not have happened at a worse time for the two farmers involved.
"These particular sheep will very likely be heavy in lamb or at least impregnated.
"It is a disaster for the rest of the flock as well because they will have been badly affected by being chased by these dogs and are at a high risk of aborting their lambs, so the financial loss to the farmer could easily run into thousands of pounds.
"This won't have been the work of one dog, it will have been at least two or three.
