History

yorkshire terrierThe Yorkshire terrier originated in Yorkshire which is a place in northern England. In mid 19th century workers from Scotland came to Yorkshire in search for work. They brought different varieties of small terriers with them. Earlier they are known as Broken Haired Scotch Terrier and then Toy Terrier. In 1874 they were officially named as Yorkshire Terrier. They begun their journey as hunting dogs and later developed as companion dogs. AKC registered the breed in 1878.

Based on the massive dog of Mesopotamia in 5000 BC, the American Molossus is the same dog recreated in the United States by and for the lovers of these giant dogs. The ancient Molossus was fierce to look at, massive in size, courageous and loyal. He was undaunted by any animal and stood up to any man attempting to hurt his master. When Rome fell the descendants of today’s Molossus were scattered and attempts to revive the breed have created carious large dogs. The American Molossus is the first true recreation that hits the mark.

The original Molossus was one of the most primitive of dogs, one of the earliest dogs that men domesticated. Their initials duties were the guarding of herds and homes against all enemies. They were incredibly loyal to their one master and stayed with him and protected him. These dogs also ate carrion and served the villages by eliminating animal carcasses. They could handle any other hunting animals such as wolves and large cats. This dog, although extinct was the ancestor of all the Mastiff-type dogs of today. The Molossus is said to be the ancestor of the St. Bernard, English Mastiff, Greater Swiss Mountain Dog, Bernese Mountain Dog, Newfoundland, Great Dane, Great Pyrenees, Rottweiler, Rottweiler and the Neapolitan Mastiff. Now these breeds have become the ancestry of the American Molossus.

According to Marcus Curtis, the founder of the new Molossus, the nearest relative of the American Molossus is the Neapolitan Mastiff. The Hines Bulldog, German Rottweiler, American Bandogge, and South African Boerboel together with the Neapolitan Mastiff were used to form the American Molossus. The goal of the founder was to make a great family pet and protector. It was specifically bred to be courageous, loyal and protective.

Like all Mastiffs the American Molossus faces a variety of potential illnesses, some brought on by its size, some not.

Cystinuria

Male Molossus can contract this inherited metabolic disease primarily. It can be life threatening and very serious as it affects the kidney and the bladder.
