Uruguayan Cimarron

The national dog of Uruguay


The origin of the Uruguayan Cimarron is uncertain. It is known to be descended from the dogs introduced by the Spanish and Portuguese conquerors. From the crossing of these abandoned dogs in Uruguay and from a natural selection where only the fittest, most cunning and strong survived, the Uruguayan Cimarron was born. The inhabitants of the time, recognising the value of these dogs, domesticated them and progressively began to use them very successfully as guardians of their establishments and in their daily work with livestock. This outstanding guard and working farm dog is now the most sought after dog breed in Uruguay. It was honoured with a stamp issued in 1995, and is currently the mascot of the National Army of Uruguay.
