Animals the keeping or use of which is regulated by statute because of their propensity to cause damage. Under the Dangerous Wild Animals Act 1976, the keeping of apes, bears, crocodiles, porcupines, tigers, venomous snakes, and other potentially dangerous animals requires a local-authority licence. A list of the animals classified as dangerous wild animals is contained in a schedule to the 1976 Act. The Dangerous Dogs Act 1991 made the breeding, sale, or possession of dogs belonging to a type bred for fighting (e.g. pit bull terriers) an offence, enabled similar restrictions to be imposed in relation to other dogs presenting a danger to the public, and made it an offence to let a dog get dangerously out of control in a public place. The use of guard dogs is strictly controlled by the Guard Dogs Act 1975.
