Great idea Sue, but be careful depending on the temperment of your Akita!
My Akita female seems to be the exception to the rule. She's the least aggressive dog I've ever had, although she is protective and barks at strangers. Scott will probably agree as he rough houses with her.
One concern I would have though is jealousy. I've seen some really jealous dogs when a new dog is brought into the household.
My last dog freaked when I brought in a stray puppy and kept it in the garage until the humane society picked it up. She marked her territory wherever she found it's scent.
