Police have received reports of sheep worrying in the Battle and Netherfield area.
Battle Police would like to remind residents it is vital that you keep your dog on the lead around livestock, even if you can usually trust it to come to call.
A police spokesman said: “At this time of year it’s a particular problem because sheep are in lamb and so there’s a risk that dog worrying could cause them to abort.
“Sadly we have received a few reports of sheep worrying in the Netherfield area. It is an offence to allow a dog to worry sheep.
“Worrying includes attacking or chasing sheep and, in some circumstances, farmers are legally entitled to shoot dogs if they are endangering their sheep.
“If you live in or near a farming area, you must make sure that your dog cannot escape from your property.”
