Hey back at ya.
You might try a vibration or shock collar. Yesterday we had an hour session of "come, stay, come, stay" that he didn't like. I put him on a long tether and made him stay. Then I would walk to the end and call him. He already knew the commands but akitas are hard headed and need reminding sometimes. He got his reminder. He didn't like it but he gets it till next time he needs reminding.
