hereAlso:
"In practice there are virtually no circumstances in which a gamekeeper might lawfully shoot a dog or cat. Gamebirds in captivity count as livestock, but your normal precautions for keeping foxes at
bay would also keep dogs out of a pen. Gamebirds in the wild have no protection other than that provided by poaching legislation. Shooting a dog or cat that is chasing wild birds would normally lead to a charge of criminal damage unless you could show that you genuinely believed the owner would have consented to the destruction of the animal, which is highly unlikely. There is the added risk that you might lose your certificate. " from
