Updated legislation relating to livestock worrying has come into force across England and Wales, introducing stronger penalties and expanded enforcement powers in response to ongoing incidents involving dogs and farm animals.
This update is particularly relevant for dog professionals and guardians who walk in rural areas, where livestock may be present.
What the law covers
Livestock worrying refers to a dog attacking, chasing, or otherwise causing distress to farm animals.
This includes behaviour that may lead to injury, suffering, or loss, even if no physical contact is made.
The legislation applies to animals such as:
- Sheep
- Cattle
- Other farmed livestock
What has changed under the new law
The updated legislation — the Dogs (Protection of Livestock) (Amendment) Act 2025 — strengthens the existing legal framework.
Key changes include:
- Unlimited fines for offences
- Expanded police powers to investigate incidents
- Greater ability for authorities to take action where a dog is suspected of involvement
These changes are designed to strengthen enforcement and act as a deterrent in areas where incidents are reported.
Enforcement and investigation
Under the new law, police and relevant authorities now have increased powers to investigate livestock worrying incidents.
This may include:
- Gathering evidence following reported incidents
- Taking action where a dog is suspected of involvement
- Pursuing enforcement measures where offences are identified
The intention is to improve response and accountability in cases involving harm or distress to livestock.
Why this matters
Incidents involving dogs and livestock continue to be reported each year, particularly in rural and farming areas.
Even well-meaning dog guardians can unintentionally put animals at risk if dogs are off lead or not under control near livestock.
This updated legislation strengthens the framework for managing these situations and reinforces the importance of responsible dog handling around farm animals.
