The Molossus dog is a large, powerful breed that has a long and storied history. The breed is believed to have originated in ancient Greece, where they were used as guard dogs and war dogs. The Molossus was nearly extinct by the early 21st century, but has experienced a resurgence in popularity in recent years.

The Molossus is a descendant of the ancient Molossian breed of dogs, which was used for hunting and guarding in ancient Greece. The name "Molossus" comes from the Greek god of war, Ares. The Molossian breed was large and powerful, with some dogs weighing over 200 pounds. They were used as guard dogs by the Greeks, and later by the Romans.

The Molossus dog nearly became extinct in the early 21st century. There were only a handful of known molossers left in the world, and most of them were living in Greece. However, the breed has experienced a resurgence in popularity in recent years. There are now molosser clubs and breeders all over the world, and the breed is once again becoming more common.

The ancestry of the Molossus dog is largely unknown. However, it is believed that they are descended from ancient mastiff-type dogs such as the English Mastiff and Neapolitan Mastiff. The first recorded mention of a "Molosser" type dog was by Aristotle in 350 BC. In more recent history, molossers were popularized by Queen Victoria, who owned several English Mastiffs.

The Molossus dog is recognized as a separate breed by several kennel clubs around the world, including the American Kennel Club and United Kennel Club. The breed standard for the Molossus calls for a large, muscular dog with a short coat and square head. They are available in many different colors including black, brindle, fawn, and white.
