Working Group is the name of a breed group of dogs, used by kennel clubs to classify a defined collection of dog breeds. Most major English-language kennel clubs include a Working Group, although different kennel clubs may not include the same breeds in their Working Group. Working Group does not define one particular type of dog. It is not a scientific classification. Working Group is not a term used by the international kennel club association, the Fédération Cynologique Internationale, which more finely divides its breed groupings by dog type and breed history.
