Spanish Mastiff History

The Spanish Mastiff, once was also known as Mastiff of Leon (a Spanish town in the North), Mastiff of Extremadura (a region in the South West of Spain) and Mastiff od Castilla-la-Mancha (a region in the South of Madrid). However, people don’t exactly know where the Spanish Mastiff comes from, though the breed is certainly native to Spain and it has likely existed for over a thousand years. Many people claim that the breed is a distant relative of the ancient Molosser dog of southern Europe , with written record from 2000 years ago referencing to white Mastiffs. Other people believe that the Mastiff has come from the famous Tibetan Mastiff, who was mentioned by Marco Polo, but this claim is without any scientific base.

Furthermore, the Spanish Mastiff has been used as a guarding of livestock and property, as well as a herding dog. The shepherds would use only one dog for one hundred sheep, and the canines would blend nicely with the flock thanks to their light coloured coat. The dogs’ coats also helped to protect them from the harsh weather in the Spanish mountains. Moreover the breed was always very connected to the flock of sheep and defended them against wolves and thieves. Written documents from 1526 show that they were usually Marino sheep, which meant that they were extremely valuable to the Spanish people and would migrate from south to north each year accompanied by the Spanish Mastiff. The breed’s role as a guardian dog on farms and on their temporary movements towards south or north had a huge significance in the past. During the thousand years a balanced character was developed, without showing aggressivity. Additionally, they were so popular that even images of them can be seen in Spanish art and literature. For example in Diego Velázquez’s painting Las Meninas, created in 1657, a brown Spanish Mastiff type dog can be seen at the front of the children, lying peacefully. There was a time when their numbers were decreasing due to the end of the sheep movements and the disappearing of the wolves but the breed has recovered its position especially in places where there have always been wolves. Given their huge contribution to history, it is no surprise that the Spanish Mastiff remains popular in Spain even today and the breed has even been named the national dog. However, surprisingly it is very rare outside of its home country. Although in Spain, these dogs are still kept as working dogs by many farmers and can also be seen at dog shows and within family homes as a pet and guard dog.

While there are record of the Spanish Mastiff dating back for many years, it was only in 1946 that their breed standard was eventually written and in 2008 the Spanish Mastiff entered into the American Kennel Club’s Foundation Stock Service group.
