The dog breed called Cimarrón dog or Criollo cimarrón is the only breed developed entirely in Uruguayan territory.

Non-domestic dogs in the world, Whether original species or breeds produced by the feralization of domestic breeds that returned to the natural environment and managed to readapt to it, they show a physical development that is totally different from this one., so it is highly arguable that this breed produced in the Uruguay as a supposed model maroons dogs mentioned in ancient chronicles and documents reflect the natural demeanor of those. All wild dogs of the world, by what is known as “convergence” evolutionary level they have long legs, erect ears, slender body, exceptions that occur in extreme climates (enormous ears of certain dogs of African deserts or small ears of Arctic foxes).

There are detailed chronicles of attacks by packs of these dogs on caravans and people, that led to the authorities of the time (end of the 18th century) they already have and encourage major massacres, reaching count by tens of thousands dead dogs.

Each dead animal was paid by the authorities of the time, requiring proof of death presented the jaw or the pair of ears of the animal. From this practice would derive the characteristic ear cut that is performed on many newborn pups., in the form of “ear of puma”.

Despite these massacres, «…a good number of mothers with their offspring conquered the mountains of Olimar and especially in the Sierra de Otazo and in the Cerros Largos», in what is now known as departments of Cerro Largo and Treinta y Tres, where many ranchers and landowners in this place, they took advantage of the virtues of this breed for working with cattle and defense of his property, beginning to raise it, preserving the mixing.

Modern traces of the breed begin to become more public in the early 1990s. 1980, When numerous breeders of Montevideo, attracted by the remarkable characteristics some specimens, they begin to develop their parenting and standardization.
