The Perro Cimarron does not need special attention in grooming because of their short coat. Brushing is not needed on a daily or even weekly basis. Wash or bathe with gentle shampoo when needed.


Descendants of the Spanish Mastiff, the Perro Cimarron was originally found in Uruguay, brought over by European settlers and traders in the 17th century. These dogs were let loose to live in the wild and eventually, they began to rapidly multiply in numbers. In order to control the over populated breed from attacking needed livestock, the government paid bounties to hunt the Perro Cimarron. This popular breed was soon adopted by ranchers and farmers who trained these dogs as guards, hunters, and fighting dogs. Not too long after, the Perro Cimarron was named the mascot for the National Army of Uruguay.
