Hokkaido vs American Mastiff - Breed Comparison | PetzLover

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 Hokkaido breed originates in Japan and is also called Ainu-ken, Ainu dog, Seta or Do-ken. The last being its common name in Japan. It is believed that the Hokkaido is descendent from the Japanese Matagi-ken, meaning hunting dog, deer hunting dog or bear hunting dog. It was the Ainu peoples that brought the breed to Tohoku. Many years later the Yayoi people brought in another breed of hunting dogs. These breeds were in isolation for most of their existence and therefore they had little influence on the further development of other breeds.

The Ainu dog was used in searches as well as hunting and became in 1937 “a rare species in Japan that is protected by law”. At that time the Official Name of the breed was set in place as Hokkaido-Inu. But they are still called Hokkaid0-Ken by most Japanese people.

This is a very rare breed of dog. It is hardly known outside of Japan and in country there are about ten to twelve thousand remaining. Of those about nine hundred to one thousand are registered in Japan every year. It is guessed that less than thirty exist outside Japan.

The Hokkaido breed is the oldest Japanese breed of dogs. Today they are great indoor companions, loyal and friendly. Most people in Japan still call them the Ainu dog.

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 Hokkaido breed is medium in size but very strong in build. Dogs bred outside Japan tend to be smaller. They have wide, deep chests, and long thick coats compared with Japanese dogs from other breeds. It is a double coat of long fur on top and short softer fur underneath for the second coat. Their ears are triangular and small while their eyes have a triangle outline. The double coat could be sesame, white, red, black, black and tan and wolf-gray.

They are an intelligent breed with an impulsive gait. They are alert, courageous and suspicious. They were used for guarding the city gates. Their skull is flat and broad and the tongue, like the chow chow, is blueish. black. With a black nose and a wedge shaped muzzle, the Hokkaido is a handsome dog. His lips are with black and tight. High set, thick tail over the back or slightly curved to the side.

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.

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.

Often breeds that are isolated like the Hokkaido, have a pretty good health history but there are a few serious issues that they face.

CEA- Collie Eye Anomaly

1/3 of all dogs have it while 2/3 are carriers. This disease is congenital and there is no cure. It affects the sclera, retina and choroid. It can be mild or it can cause blindness.

Hip Dysplasia

Affecting joints and cause arthritis and lameness.

Luxating Patella

Floating kneecap – not as prevalent here as in smaller dogs.

Heart Mumurs

Idiopathic Seizures

Seizures of an unknown origin. Can be treated with medication not cured.

Psychogenic Polydipsia

Excessive, uncontrollable urge to drink large amounts of fluid without a stimuli.

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

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.

Make sure they learn to love to play so that they don’t become lazy as they age.
