For example, the Japanese Akita originated in Japan sometime during the 17th century, while the American Akita originated in America sometime during the 1940s. This is because of American soldiers bringing the Japanese Akita over to the United States during this period of occupation.

However, they are both extremely loyal dog breeds as well as capable learners, so long as all anxious behavior is dealt with early.

Are American Akitas Good Off Leash?

Now that we have found out some great information surrounding these two types of Akitas, are they good pets and specifically are they good pups to let off the leash?

The short answer and probably most agreed upon answer is to keep your Akita’s leash on whenever you are in a public space or where they could run away. As well trained as an Akita may be, they tend to have a streak of not listening too well at times, and with their guardian type mentality they could be potentially dangerous.

Off leash, an Akita could attack a human and cause real pain and suffering, especially to a child. The most likely accident, however, would be an Akita attacking another dog of the same sex. They are known for this type of aggression, and it is best and most responsible to keep them on a leach for everyone’s safety and well being.
