Hazards

To minimise the risk of sheep being trapped in snow or being unable to gain shelter, care should be taken in siting shelters, shelter belts and fences.
As far as is practicable, sheep should be prevented from gathering in places where they may be buried by snow; Where possible, they should be allowed to move naturally or be shepherded into safer areas.
All sheep should be removed from areas that are in imminent danger of flooding.
Young lambs should be protected, as far as possible, from hazards such as open drains and predators.
Any dog is a potential hazard to sheep and should be kept under control on agricultural land. Well-trained sheepdogs, however, can greatly facilitate gathering and handling, particularly under extensive conditions. They should be trained so that they do not grip sheep. Sheepdogs should be well cared for and maintained in good health. They should be regularly wormed to eliminate endoparasites.

The Animals Act 1971 lays down measures with respect to civil liability for the protection of livestock from dogs, and the Dogs (Protection of Livestock) Act 1953 makes it an offence to allow a dog to worry livestock.
