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.
Known as the Guatemalteco Bull Terrier or Guatemalan Molosser, the Dogo Guatemalteco is also known as the Bull Terrier Guatemalteco, Guatemalan Bull Terrier, and Guatemalan Molosser.
This big Molosser-type dog originates in Guatemala. In the 20th century, it was known as the Bullterrier Guatemalteco, but at the end of the century, it was changed to Dogo Guatemalteco.
Today, while the dog is kept as a companion dog, most are working guard dogs. The Dogo Guatemalteco isn’t recognized by any major international kennel clubs. However, the Kennel Club of Guatemala has given full recognition to this dog and it was in 1981 that the Guatemalan government named the dog as their national dog breed.

Like all Mastiffs the American Molossus faces a variety of potential illnesses, some brought on by its size, some not.
This could easily be a function of its massive size. It is a degenerative disease and can cause the dog to become lame. In many cases the vertebrae can fuse, or severe pain can result. This is mostly seen in older members of the breed.
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.
This is essentially Cervical Vertebral Instability (CVI) and is caused by the pressure of the nerves in the neck and cervical spinal cord. This compression can cause deformity, pain and abnormal stance/gait. IT has been attributed to the nutrition needs and rapid growth of the Mastiff breeds.
Like all giant Mastiff breeds the Molossus can have skin issues from the wrinkles, dysplasia in the joints which we will address below.
This dog can be susceptible to skin allergies. The skin is sensitive and prone to rashes.
Another health concern with this dog because of his white coat, is congenital deafness. The deafness could be in one- or both ears.
The dog could also experience lameness, of which the most common problem is hip dysplasia. Because skeletal problems occur in this breed, it is advisable for owners to have their pet tested by the Orthopedic Foundation for Animals.
Remembering that this is a very, very large dog you need to be careful about nutrition and how fast your puppy will grow. American Molossus puppies need four meals a day until 12 weeks old. Then until they are 6 months old feed then 3 times a day. Finally, from 6-month-old puppy to adult – feed them twice in 24 hours.
At one year either feed them once or two small meals.
Many people feed their Molossus eggs, vegetables, fruit, and cottage cheese as ten 5 of the total for the day but avoid other table foods. The Molossus can become very picky about what he eats if you feed him too many table scraps.
In addition to the health problems listed above, the American Molossus is also susceptible to: Ditichiasis – Eyelashes that are in the margin of the eyelids and can cause eye irritation. May require surgery to correct.
Could cause blindness if not removed. Ectropian/Entropion: Eversion and inversion of eyelids which cause ocular irritation.
This is a degenerative disease which causes the dog to go blind. It is a disease the affects the retinal visual cells, first causing night blindness then day blindness. A DNA test is available for detecting PRA in all Mastiff breeds.
Common in large breeds and especially in giant breeds like the Molossus. Multiple forms and causes but all can cause pain and lameness.
Do to wrinkles and loose skin – check often for moisture and infections.
The is a problem based on a variety of possible causes. It happens when the puppy is between 6-16 months of age. Lameness occurs over time in one limb or in all. It can be intermittent and might be caused by diet, genetics, stress, autoimmune or metabolic issues or infection.
This issue is developmental as the dog’s toes turn either inward or outward, then as the condition advances the dog suffers fever, pain in all joints, lethargy and the inability to stand. This happens when the dog consumes too many calories for his activity level in the development times.
The American Molossus is not a couch potato. He needs to be walked at least twice a day and loves to play fetch. He will be greatly benefited by obedience training. Do not overdo it with exercise but make sure they don’t just lay around.
The coat of the dog is short and harsh and it sheds throughout the year. While he is still looked upon as a low maintenance dog, regular brushing will be required twice a week.
Because he is a dog breed that is susceptible to skin allergies, bathing isn't necessary as it removes the dog’s natural oils.
Other areas of grooming for this dog are brushing his teeth twice a week, trimming his nails and checking his ears.
Always choose a high quality dog food for your Dogo Guatemalteco and look at the feeding recommendations on the packaging.
When you feed your pet kibble, you can also mix in some cooked brown rice, vegetable and chicken for variety and contentment.
Raw meat is also advised from time to time. Don’t just go on and on through the years feeding your dog the same amount of food, as there are factors to take into account when deciding on food quantity. The age of your dog, it’s stage of life and its activity levels will mean regulating your pet’s food to match his needs.
