Today I was talking to an American Akita breeder at an FCI competition in Puerto Rico and he is telling me that the Japnese version of the akita is the one that is more aggresive towards others dogs. He told me that the american counterpart is an easy going dog and more benign with others dogs. He got two beautiful females that are from Oregon, but his remark of the difference of the two breeds kept me thinking, because in the breed profile here, the american akita is supposedely, the bad guy with other dogs. The same thing happen with Tosas, the american ones are more playful, like English mastiffs, and more friendly. Just a comment. :)
