Akita Inu vs American Mastiff - Breed Comparison | MyDogBreeds

The 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.

The history of the American Mastiff is entirely tied to the old European Mastiffs but in particular the English Mastiff. The developers of the American Mastiff crossed the English Mastiff with the Anatolian Mastiff at the Ohio kennel, Flying W Farms. The founder of this breed is Fredricka Wagner. Because of this the English Mastiff and the American Mastiff look very much alike. The difference between the two is that the American Mastiff was bred to have less health concerns than the English Mastiff and without the drooling. In 2000 the CKC acknowledged that the American Mastiff and the English Mastiff were separate breeds.

The 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.

This crossing of the English Mastiff and the Anatolian Mastiff resulted in a Mastiff with a much drier, less drooling mouth than the other Mastiffs. This is a giant, massive dog – powerful and muscular. With a wide head that is rectangular rather than square. Their eyes are dark amber, and their ears are high on their head and rounded. With a medium size muzzle, black mask and heavy head, the American Mastiff is a handsome dog.

Their chest is broad, deep with ribs that extended backward. He has strong legs that are parallel and wide set. He also has a long tail. Puppies of the American Mastiff are born almost black and as they grow their coat color lightens. In addition, it is important that they have a wrinkled forehead as well and a scissors bite is preferred.

The 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.

A love of children and devotion to his pack (family) is bred into the American Mastiff. He is non-aggressive unless you threaten his family or his children. Then he becomes courageous, protective and defensive. This is a gentle giant most of the time, however due to size and the need for strong leadership, the American Mastiff should be socialized and trained early. If they are socialized and trained they will be calm, gentle dogs. They will remain protective and alert, but they will be friendly with strangers. They love to please their people and being highly intelligent they learn fast.

The 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.

American Mastiffs seem to have fewer health issues than other larger giant breed dogs. However, they can experience allergies as many large, wrinkled dogs do. They also might have a tendency toward eye issues, hip dysplasia, cancer and heart disease. Bloat might be the most life-threatening issue many American Mastiffs experience.

Caring 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.

Giant breeds like the American Mastiff are known for growing rapidly as a puppy and therefore proper feeding and nutrition is essential. The slower your American Mastiff grows, the better. Make sure your puppies get enough phosphorous and calcium in their high calorie diet. Free feeding is not recommended. Feed puppies up to 4 small meals per day and feed adults twice a day.

Health issues

As previously mentioned this breed is a fairly healthy one, There, are however, certain evaluations you should do with your American Mastiff puppy to be sure she is in good health. These tests would include an elbow and hip evaluation to check for dysplasia. He should have an ophthalmologist and cardiologist examine him as well. Most American Mastiffs will not have any problems, but these evaluations will help to prepare you if they do. The wrinkles in your dogs; face, around the eyes and muzzle must be kept clean as they can become infected if you don’t.

Exercise and games

Unlike the way he looks, the American Mastiff is not a couch potato, but neither are they a high energy, exercise machine. They do well living in apartments or homes, with or without a fenced in yard. They need a long walk every day. They need mental stimulation through exercise and games. Make sure they learn to love to play so that they don’t become lazy as they age.
