“Dog owners are reminded that allowing dogs to chase livestock or be at large among livestock is an offence. Dogs are naturally curious and have an instinct to attack so it is recommended that they are always kept on a lead under close control.
“Livestock owners are legally entitled to protect their animals, which can result in the destruction of the dog if necessary to protect the lives of other animals.”
