Twelve sheep killed in two years at Northam Burrows
A total of 12 sheep have been killed by dogs at a nature reserve in north Devon, a local authority has revealed.
Torridge District Council and police have asked people to report information on any dogs that are worrying the animals, which is a criminal offence.
The animals were killed at Northam Burrows between the beginning of 2010 and the start of 2012.
PC Dick Rowlands said: "We need descriptions of the dog, owner and car, especially the registration."
David Morgan, environmental protection manager at the council, said: "It is crucial that a clear message goes out to the small number of dog owners who do not keep proper control of their dogs.
"It is not acceptable that lambs and sheep are being injured and killed in such an unnecessary manner."
Northam Burrows is part of the United Nations Biosphere reserve and is a Site of Special Scientific Interest.
