The Hunting Act 2004 prohibits the use of dogs to hunt wild mammals except under the following conditions:
1. Stalking or flushing undertaken for the purpose of:
(a) preventing or reducing serious damage which the wild mammal would otherwise cause to:
(i) livestock,
(ii) game birds or wild birds (within the meaning of section 27 of the Wildlife and Countryside Act 1981 (c. 69)),
(iii) food for livestock,
(iv) crops (including vegetables and fruit), growing timber,
(v) fisheries,
(vi) other property, or,
(vii) the biological diversity of an area (within the meaning of the United Nations Environmental Programme Convention on Biological Diversity of 1992).
(b) obtaining meat to be used for human or animal consumption.
or
(c) participation in a field trial; “field trial” means a competition (other than a hare coursing event within the meaning of section 5) in which dogs:
(i) flush animals out of cover or retrieve animals that have been shot (or both), and
(ii) are assessed as to their likely usefulness in connection with shooting.
2. Stalking or flushing out takes place on land:
(a) which belongs to the person doing the stalking or flushing out, or
(b) which he has been given permission to use for the purpose by the occupier or, in the case of unoccupied land, by a person to whom it belongs.
3. Stalking or flushing out does not involve the use of more than two dogs
Reasonable steps must be taken to ensure that, as soon as possible after being found or flushed, the wild mammal is shot dead by a competent person and, in particular, each dog used in the stalking or flushing is kept under sufficiently close control to ensure that it does not prevent or obstruct the animal from being shot.
However, an exemption to the Act allows the use of a single dog below ground for the purpose of preventing or reducing serious damage to game birds or wild birds which a person is keeping or preserving for the purpose of their being shot.
Further exemptions include the hunting of rats and rabbits if it takes place on land which belongs to the ‘hunter’ or on land which he has been given permission to use for the purpose by the occupier or landowner.
Any hunting of mammals with dogs will be illegal if carried out without the permission of either the landowner or, in most circumstances, the occupier. As a result, many poaching offences (involving dogs) will also involve illegal hunting. However, simply being accompanied by a dog while poaching or trespassing does not amount to illegal hunting.
