Police said chasing sheep can cause them unnecessary stress and result in death

Police are warning walkers with dogs to keep their animals under control after an attack led to the death of nine sheep.

North Wales Police said walkers should keep dogs on a lead when crossing land where livestock is grazing.

Earlier this month the flock of sheep was chased by either one or two dogs in a field at Efenechtyd near Ruthin, Denbighshire.

Police said they believed the animals were chased to their death and several were mauled in the incident.

PC John Harrison said: “We are asking ramblers with dogs using public footpaths across farmland where animals are grazing to keep their dogs on a lead so they do not chase sheep or cattle.

“Chasing sheep can cause them unnecessary stress and result in death.”

He also appealed for anyone who saw the incident to contact him.

He said: “This particular incident happened sometime between the evening of 13 February and 8pm on 14 February. Anyone who witnessed the incident or has information should call me, PC 2824 John Harrison, on 101.”
