"Even a normally well-behaved dog can instinctively chase or attack livestock if given the opportunity.
"Recent changes in legislation under the Dogs (Protection of Livestock) (Amendment) Act 2025 have strengthened police powers and increased penalties for livestock worrying.
"The law now makes clear that a dog does not need to physically injure animals to commit an offence - chasing or causing distress to livestock is sufficient.
"Courts can impose unlimited fines, and police have enhanced powers to seize dogs and gather evidence.
"Dog owners are reminded that they are responsible for keeping their animals under control at all times, particularly around livestock."
Anyone with information, no matter how small it may seem, is urged to call 101, quoting occurrence 26000160007.
