History of the breed

In 1232, King Jaime I conquered the archipelago of the Balearic Islands. With the king, several large strong dogs travelled between Alans and Bulldogs of the Iberian Peninsula. These dogs would give birth to the current ca de Bou.

In 1713, thanks to the Treaty of Utrecht, the Balearic Islands became English colonies. During the English rule on the islands, dog fighting and dog-bull fights, “sports” common in England at the time, were encouraged.

It was at this time that they started crossing the existing dogs on the islands in order to obtain the most suitable fighting dog for the high temperatures of the Balearic Islands. Of course, bulldog dogs and other English moloids were also used at these crosses.

The result was the Ca de Bou. Dog and bull fighting took place not only in sports arenas, but also because butchers used dogs to control and kill cattle. Hence the name of Ca de Bou, which in Catalan means “bull dog”.

Years later. With the return of the Balearic Islands to the Spanish Crown and the prohibition of dogfights, the Majorca mastiff continued to be used as a watchdog and as a butcher ‘s assistant.

Today, the breed is little known outside the archipelago that saw them born, and even in Mallorca and the other Balearic Islands, its population is small.
