Mastiff, for a long time accompanied the herds of sheep in its migratory paths
from the Aragonese and Navarrese Pyrenees to Maestrazgo. Their main function
was to guard and protect the herds and their masters from wolves, bears, and
During the 20th
century, especially after the Spanish Civil War, due to economic difficulties,
the mastiff’s popularity went into decline as it was very expensive to keep a
dog of its size. In the 1970s a group of fans started the job of recovery of
the breed through the few specimens that were in the countryside and still had
typical features of the ancient mastiff.
Mastiff breed is now being taken from its native region and promoted as a pet
in other countries like USA by the Pyrenean Mastiff Club of America. It was recognized
by the Fédération Cynologique Internationale in 1982.
