I'm surprised that Akitas are on that list, I've never heard of them being aggressive. I know our local Humane Society does in home visits for people who want to adopt what they consider "bully" dogs. Dobermans, Pit Bulls, Rottweilers, and Chows are all on their list.
They funny thing is the most aggressive dog I know is my mixed breed 20 pound Chico. I adopted him fromt The Humane Society and he was so sweet and friendly. But once he'd realized he had his forever home with me, he got super protective. He hates all strangers with a passion, especially anyone who wants to approach his pack (me, Suki, and Polamalu).
