I forgot to add that for me, food aggression is one of the easiest issues to deal with. I feed raw, so my dogs are handed each piece of meat. They all go out with me and I hand each of them one piece at a time. They take it, eat it and wait for the next piece. Every day, I take at least one piece back from each dog, just to reinforce the fact that I give and I can take away. They will not take a piece of meat out of a bowl, even if I set the container down. On the rare occassion that they get impatient and do take one, a simple no is all that is required for them to drop it. Cody will from time to time growl, when I take his back, but he has learned, if he growls, I still take it away and then he has to eat it, with me holding it, the entire time. Dogs with a "hard" personality are more of a challenge than others, but they are so worth the time, patience and effort. Consistency is the key to training and living with these breeds. I don't have an Akita, but I don't think they are any more difficult than Tibetans and Caucasians.
