There's a difference between an Akita and an Akita Inu?

Strangely enough there is! The original breed of Akita, known as the Japanese Akita or Akita Inu is native to the island of Honshu in the region of Akita, it's breed standard has remained unchanged for centuries. The Akita Inu is the largest of all the Japanese Spitz breeds and is a solid powerful dog. They are an extremely strong breed, both mentally and physically and their main separate feature from their American breed is their image. The Akita Inu will never have a black mask, brown is permitted on white but black is preferred.
The American standard Akita though has a wide variety of colouring including white, bridle or pinto, white Akita's will have no mask though black masks are accepted in the American breed.

In Japan, U.S.A, Canada and many other countries around the world the two different breeds of Akita are recognised as separate breeds and both can vary in different sizes also.

The American Akita male averages around 66 - 71 cm and can weigh up to 54kgs, while females grow to around 66cm and weigh up to 50kgs.
The Japanese Akita is a smaller dog with males growing up to 66com and weighing up to 54kgs, females can get to the same size as the males also.
