Dogging is a British English slang term for engaging in sexual acts in a public or semi-public place or watching others doing so.
The original definition of dogging—and which remains a closely related activity—is spying on couples having sex in a car or other public place,[4] and the term had been in use on Britain's railways for many years.
[5] There is some evidence on the Internet that the "craze" has begun to spread to other countries, such as the United States, Canada, Australia, Barbados, Brazil, Denmark,[6] the Netherlands, Norway,[7] Poland,[8] and Sweden.
As of 2010,[update] Association of Chief Police Officers (ACPO) policy was that arrests are a last resort and a more gradual approach should be taken in such circumstances.
"[13] An alternative etymology posits dog walking as the origin of the term; audience members, and indeed participants, could use the ordinary exercise of their pets as cover for their sexual assignations.
