PetzloverAmerican Molossus is originated from United States but New Guinea Singing Dog is originated from Papua New Guinea. American Molossus may grow 28 cm / 12 inches higher than New Guinea Singing Dog. American Molossus may weigh 33 kg / 73 pounds more than New Guinea Singing Dog. American Molossus may live 6 years less than New Guinea Singing Dog. Both American Molossus and New Guinea Singing Dog has almost same litter size. Both American Molossus and New Guinea Singing Dog requires Moderate Maintenance.
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.
In 1957 the New Guinea Singing Dog was “discovered” in the Highlands of Papua New Guinea and he is found no where else. There is a lot of debate among scientists, taxonomists and biologist as to what is really a species and what is a subspecies. When the NGSD was found he was classified as a new canid species then in 2007 they were downgraded to a subspecies.
Today the NGSD is considered to be a wild dog and a primitive dog. They have lived in Papua New Guinea in the Highlands for thousands of years. They are closely related to other wild dogs, such as Australia’s dingo. They are today as they were a thousand years ago – wild. So wild that many counties have them in their zoos.
With the right care and enough socialization, they do very well as companion animals living with people. They are difficult to domesticate however and the person who owns one should be a part of the NGSD community in order to get support, share issues, and learn from others who have lived with these “wild dogs” for many years.
Any New Guinea Singing Dog found in North America or Europe is a direct descendent of two couples that were taken to zoos in China and Australia. The NGSD makes a howling sound that modulates and undulates through a wide series of tones. No other dog makes this musical sound. Rare even in New Guinea today, the Singer is thought to be the rarest of all dogs.
The only organization that recognizes the Singing Dog is the UKC and they are allowed in UKC competition. The NGSD now holds the classification of a domestic dog – a Canis lupus dingo - which is a subspecies of Canis lupus. In 2016 a group of 15 wild dogs were photographed for the first time ever. Prior to this the NGSD were never seen in more than pairs.
It is believed that they do not live and operate in packs, but rather solitary, pairs or family groups where both the parents do the work of raising the pups.
This is a giant, massive dog in every way and this recently developed standard makes that very clear. The Molossus should be heavy bones, muscular with a lot of loose skin and wrinkles of all kinds, everywhere. He is an intimidating presence, with a massive square head, broad shoulders, height and mass. No, the American Molossus is not athletic, but he certainly is intimidating.
His head is massive in comparison to his body and it must be square. He has extensive wrinkles and pendulous lips and dewlap. The face is all folds of skin and wrinkles. Deep set eyes, drooping upper lids and lower lids as well as an intimidating expression. His brow is well developed with a marked frontal furrow. The nose is large, and the muzzle is about a third of the length of its head. It is short and broad. Everything about the head must be square. It’s neck and body are powerful and muscular. The chest is deep, wide and barrel like. The back is also powerful and muscular. The front legs are heavy and muscular while the hind legs are broad, strong, powerful and wide-stance. Do not remove the front dew claws. His tail is thick and wide then gradually tapers at the tip.
The New Guinea Singing Dog is a medium sized dog with short legs and a broad head. They are about average height and they are very limber and flexible. They can rotate their paws and spread their legs at much greater angles than the average canine. Thus, they can easily climb a tree. They can jump like a cat.
They have very reflective eyes that are shaped like almonds and have dark rims. The color of the eye can be dark brown to dark amber. It is also believed that they can see better than other domestic dogs in low light settings. Their pupils let in more light due to pupils that are wider than most other dogs.
The ears of the NGSD are lined with fur, pointed and erect. The are forward laying and can be rotated in order to hear even the farthest and faintest of sounds. There are dark guard hairs on the spine and back of the ears and tail. On young dogs the muzzle is black but by age 7 it is already beginning to turn gray.
The American Molossus is an intimidating massive giant bred for protection and guard duty. He is incredibly loyal to his family and courageous in his protection of them. They are guard dogs, not attack dogs. Their simple appearance is usually enough to frighten off anyone intending harm on their families. He is in reality a loving giant. He is intelligent and stable with a strong desire to please his owner. He is a calm yet vigilant presence in the home.
Because the Molossus is so large, it is recommended that the puppy be socialized and trained professionally. It takes a strong owner to handle this breed. They need to know the rules and have the rules consistently applied. The owner must be the pack leader.
They could be, but it must be remembered that this is a wild dog.
Varying the pitches when howling
It’s possible but not recommended. Leave them wild.
Highly intelligent but trainability is questionable unless well socialize and attached to their people.
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.
Though the breed is not extinct – it is so wild and secretive that there is no history or record of any health problems. However, the small number of domestic companion animals have shown health issues in recent years.
Pancreatitis – can be chronic or acute. If chronic it needs to be treated and diet changed. If acute it is usually deadly.
Hip Dysplasia – can cause lameness or arthritis.
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.
In the wild both pups and adults are thought to eat small mammals and birds as well as fruits. In homes feed a high protein diet. Because of the tendency toward pancreatitis do not feed raw or under cooked meat. If feeding meet do so in small amounts well cooked, very lean. Stay away from the fat. Feed puppies very small amounts. ¾-1 cup high quality dry puppy food twice a day.
Same as the puppy when it comes to meat although you could give the adult a little more. 1 ½ cups od high quality medium breed dog food twice a day.
In the wild there is no indication of health issue. A very healthy breed.
The NGSD needs a lot of stimulation both mental and physical. They must have a daily walk and somewhere to run. They are escape artist in homes. Remember they can jump like cats and climb trees. If their head can pass through a hole, so can the rest of their body.
