Dogo Cubano also known as Cuban Mastiff, Cuban Dogo and Cuban Dogge is an extinct

There are many theories on where this dog actually descended from. Some say the Mastiff group was descended from the Alaunt which originated from the Caucasus Mountains and lived among the Alan tribe. Others claim that they were from the time of the Pre-Roman Celts in Britain and were related to a giant war dog which is also related to the English Mastiff, while others say they originated from the Tibetan Mastiff. They could have also been descendants from ancient Egyptian war dogs that spread from the help of Greek and Phoenician traders. While any of these theories may be true, the most common theory is that they were related to the ancient war dogs in Greek and Roman armies, the Molossus. One thing that is agreed upon is that they are part of the largest dog groups known as either the Alaunts, Molossers, Mastiffs, or Dogues.

These dogs were most popular in Spain and England where they were bred as sport dogs for dog fighting, war dogs, or guard dogs. Spaniards would bring their own Mastiffs on their ships when traveling to new countries. As they explored Cuba for the first time, the Spaniards let their war dogs loose, giving them commands to attack the native people. The Spaniards took over the island, and so did their giant Mastiff and Alano dogs. While on the island, these dogs bred together and eventually there was no differentiating between the two large breeds and they became known as the Dogo Cubano.

These dogs were eventually crossed with scent hounds in order to increase their skills of tracking down slaves in Cuba while Spain was still in power. The cross between the Spanish scent hounds gave the breed slightly longer muzzles and longer ears that before. Because there are no records of Spanish scent hounds being that imported into Cuba, some do not believe they were ever crossed with these dogs.
