National Sheep Association CEO Phil Stocker said:
"Sheep worrying by dogs is a crime but openness from the dog owner can mean a more amicable resolution can hopefully be achieved.
"Often dog owners simply do not realise their pet is capable of doing so much damage, and while we appreciate this crime is not one that any animal lover would set out to commit, taking responsibility is crucial and could help reduce cases for the future."
