History

The Molossus has always been a popular dog and they have been around since ancient times. Mastiff type dogs are termed as Molossus.

Of course, when looking at the origin of the dog, there are many unsubstantiated claims about it. It has always been believed that the Molossus was a Mastiff-type dog, ferocious in battle. The Romans were dog breeders and recognized that the Molossus was a talented dog – good at guarding and herding.

Over the centuries the dog has changed but it is believed it was a Mastiff-type dog with a number of other breeds included in its origins such as the Rottweiler, Pug, Bulldog, Great Dane, Alano Espanol and Saint Bernard.

The Molossus isn’t a dog breed itself but rather a category that other dogs belong to. Today there are Molosser clubs and Molosser shows around the world.

akita inuThe Akita Inu, originating from Japan's snowy Akita Prefecture, has a long-standing legacy as a powerful hunting dog and loyal companion. Bred in the 1600s to track large game like boar and bear, the Akita quickly earned its place among Japanese nobility as a guardian and symbol of courage.

Its dignified nature and unwavering loyalty were immortalized in the true story of Hachikō, an Akita who waited nearly a decade for his deceased owner at a Tokyo train station. This devotion captured national and global admiration, leading to the breed’s recognition as a national treasure in Japan.

After World War II, American soldiers introduced Akitas to the West, giving rise to a larger, more robust variation known as the American Akita. Today, the Akita Inu remains a cherished breed worldwide for its strength, loyalty, and quiet dignity.

Description

This Ancient dog breed from Greece has different descriptions of what it really looked like. It seems to have always been large to medium sized dog standing in the region of 50 to 76cm in height and weighing anything from 25 to 55kg.

The coat is mostly short and smooth and can be in a host of different colors. They are large boned dogs, solidly built with medium sized floppy ears, a short, thick neck, short, broad muzzle and a long tail which was later docked.

Molossers typically have heavy bones, pendant ears, and a relatively short and well-muscled neck, with a short, broad muzzle. These Molossers have always been used for a variety of jobs where strength, perseverance, speed and braveness are required. They have been used as rescue- and guard dogs, protecting livestock from predators.

Temperament:

The Molossus dogs all have the same kind of characteristics which have been bred into them. From their working days, they are known for their tremendous courage, taking on wild animals to protect their livestock.

They are territorial, wanting to protect their human family and home from intruders.They have also been bred to be loyal, loving family pets, and being highly affectionate, they want to be involved in the activities of the family.

This breed is gentle and loving, social and active and gets on well with other pets in the home as well as with children. They’re intelligent dogs and will need to be trained and socialized to ensure they are obedient and amicable with visitors to the home.

akita inu puppy - descriptionThe Akita Inu is a large, powerful, and dignified dog breed known for its striking appearance, quiet nature, and unwavering loyalty.

Originating from Japan, it has a broad head, erect triangular ears, and a plush double coat that comes in red, white, brindle, or sesame, with characteristic urajiro (whitish markings). The Akita carries itself with pride and confidence, often aloof with strangers but deeply affectionate and protective toward its family.

Calm, intelligent, and strong-willed, the breed requires early socialization and firm, consistent training. Though not ideal for first-time owners, the Akita Inu is a loyal guardian and devoted companion for those who understand and respect its independent spirit.

Characteristics

The Molossus, contrary to what many people think, isn’t a vicious dog, but rather a good natured dog that makes a wonderful family pet.

These dogs are known also for being hard working dogs with characteristics of bravery. They are dogs who may look fairly tough, but they are actually gentle, calm and sensitive. It’s a bad upbringing from the owners that gives any dog bad characteristics.

Train your Molossus, have him socialized and be a responsible and loving dog owner, and these dogs promise to make you a splendid family pet.

akita inu dog - characteristicsThe Akita Inu is a large, noble, and powerful breed known for its dignified presence, strong loyalty, and quiet confidence. Originally bred for hunting and guarding, Akitas are naturally protective, courageous, and independent thinkers.

They form deep bonds with their family but are often aloof with strangers. Calm and clean by nature, they rarely bark without reason and carry themselves with elegance and strength.

Their double coat is thick and weather-resistant, requiring regular grooming, and they shed heavily, especially seasonally.

While intelligent, Akitas can be stubborn, so they thrive best with experienced owners who can offer consistent training and leadership. With proper care and socialization, the Akita Inu is a devoted, majestic companion.

Health Problems

These large dogs are particularly prone to health issues such as hip dysplasia, a genetic condition. A poor diet as well as environmental factors can contribute towards the disease too as well as rapid weight gain and obesity.

This disease develops because the dog’s hip joints haven’t developed properly. The hips then partially dislocate, and the dog has pain and battles to get around. If your dog shows signs of hip dysplasia, he will need to get to the vet to do a physical exam and come up with a treatment- and management program.

akita inu puppies - health problemsThe Akita Inu is generally a strong and resilient breed, but it is prone to several genetic and breed-specific health issues.

Common concerns include hip and elbow dysplasia, progressive retinal atrophy (PRA), and hypothyroidism, all of which can affect mobility, vision, and metabolism.

The breed is also susceptible to autoimmune disorders like VKH-like syndrome and sebaceous adenitis, a skin condition causing hair loss and irritation. Additionally, Akitas may experience bloat (gastric torsion), a life-threatening emergency common in deep-chested dogs.

Regular veterinary care, proper diet, and responsible breeding practices are essential to help minimize health risks and ensure a long, healthy life.

Caring The Pet

Exercise:

These dogs were bred to be working dogs and they have always spent their time outdoors performing a guarding or rescue role. Today they require a lot of exercise – walks and ball games – as they are dogs with a lot of energy.

Diet:

Essentially a large breed, the Molossus will need a commercially manufactured food of high quality if you opt to make use of the convenience of these foods.

Make sure to choose one manufactured for large breeds and which is free of a host of bad ingredients such as corn, soy, wheat, dairy, artificial colors, sweeteners and preservatives.

You want dog food which is high in protein and fat. Try and include some home-cooked food such as boiled chicken, brown rice, pasta and vegetables. An ingredient to look out for in your dog’s food is omega-3 fatty acid to help keep the skin and coat shiny and healthy. Puppies particularly benefit from DHA, or Docosahexaenoic acid, a form of omega-3 fatty acid that is good for brain development.

Grooming:

Brushing the dog’s coat twice a week will be necessary to remove loose hairs, especially during the shedding period. When you brush him, check for ticks and fleas and speak to your vet about flea treatment if necessary. Ears and eyes should be checked and cleaned regularly.

akita inu dogs - caringCaring for an Akita Inu involves commitment, consistency, and understanding of the breed's unique needs. They require regular grooming, especially during seasonal shedding, with brushing at least 2–3 times a week and daily during coat blow periods.

Akitas thrive on routine exercise, such as long walks or playtime in a secure area, but they aren’t overly energetic. Training and socialization should start early, using positive reinforcement and calm, firm leadership to manage their independent and protective nature.

They are best suited to homes where they are the only pet or properly introduced to others. Akitas are clean, quiet, and typically bond closely with their family, so providing mental stimulation, affection, and clear boundaries is key.

Regular vet checkups, a balanced diet, and proper social interaction help keep your Akita healthy, happy, and well-adjusted.
