Brief historical summary

The origin of the Cimmarón Uruguayo is uncertain. It is known to be descended from the dogs introduced by the Spanish and Portuguese conquerors. These dogs left in the country crossed among themselves. Natural selection had as a result that only the fitter, the stronger and more clever individuals survived. This is how the Cimarrón was born. The inhabitants of the time, recognizing the value of these dogs, domesticated them and progressively began to use them successfully as guards of their estates and as herding dogs in their daily work with cattle.
