Police are urging dog owners to keep their pets under control as the lambing season starts.
The appeal comes after a sheep in Patrick was killed at the weekend.
The incident happened between Saturday and midday on Sunday, when officers think the animal was attacked by a loose dog.
They are now appealing for witnesses to come forward, and say dogs may face fatal consequences in certain circumstances and their owners held responsible.
