The Biggest Loser is a reality television show which started in the U.S. in 2004. The show centers on overweight contestants attempting to lose the most weight and to fight for a cash prize. There are different variations of The Biggest Loser around the world. Each country has made its own adaptation to the show; however, the contestants always have the same goal: to lose the highest percentage of weight (or most weight) to become the Biggest Loser.
A similar programme, Operation: Transformation, airs on Irish television on RTE One, however it does not have a competitive format.
Dog breeds are groups of closely related and visibly similar domestic dogs, which are all of the subspecies Canis lupus familiaris, having characteristic traits that are selected and maintained by humans, bred from a known foundation stock. The term dog breed is also used to refer to natural breeds or landraces, which arose through time in response to a particular environment that included humans, with little or no selective breeding by humans. Such breeds are undocumented, and are identified by their appearance and often by a style of working. Ancient dog breeds are some of the modern (documented) descendants of such natural breeds.
