Dog owners risk unlimited fines under new livestock laws

Dog owners are being warned they face unlimited fines if their pet chases livestock as the UK enters peak lambing season.

Ecologists from leading ecological consultancy Arbtech.co.uk are urging the public to exercise caution in the countryside by keeping dogs on leads at all times and following hygiene guidance to protect animals.

New laws are set to come into effect on Wednesday 18th March 2026 that will strengthen the protection of livestock from dog attacks. *

Those who own or are responsible for a dog that chases livestock could face unlimited fines – up from £1,000 – and police now have powers to detain dogs believed to pose an ongoing threat to livestock. *

Lambing season in the UK runs from February through to April, with peak lambing activity typically happening from March.

As footfall in the countryside increases, livestock worrying becomes a major concern for farmers, with a recent survey finding that 87% of sheep farmers experienced a dog attack on their flock in the past year. *

Livestock worrying can severely distress ewes, lead to exhaustion, cause miscarriage, and even death.

It’s essential that dog owners always keep their pets on a lead and follow local signs and guidance to help protect farm animals and respect working farmland.

Owners are also reminded to always pick up after their dog and dispose of waste responsibly, as dog faeces can carry parasites that may be fatal to sheep.

A spokesperson for Arbtech said: “Even the most well-behaved dog can cause serious harm if allowed to roam freely near flocks, and in the worst-case scenario the consequences can be fatal.

“Livestock worrying is a real cause for concern amongst sheep farmers, and with new laws coming into effect it highlights how seriously the issue is being treated.

“Dog owners now face unlimited fines and the prospect of having their pet detained if caught chasing livestock. It’s essential owners are responsible so the countryside remains a safe place for both people and animals.”
