Many good and interesting points.
What I am about to say is simply my experience with Akitas. IMO Akitas have strong personalities with qualities distinct from any other breed with which I am familiar. They can seem quite arrogant, but really they simply respect themselves highly. Treating an Akita like other dogs is a set-up for conflict. The AKC video on the Akita shows one being given the command to jump an obedience fence. The Akita goes to a tree, lifts its leg, THEN comes back to the fence and jumps it.
Akita people laugh in recognition when they see this one. I have universally been told that Akita should never be put through shutzhund (sp?) work because they already are quite willing and able enough to take on humans and that such training would result in an animal that was too much for society.
For someone to be right for Akitas and vice versa there needs to be a desire for an independent minded dog whose respect you must earn. Its a hard thing to describe, but when it is there, a disapproving tone can leave the dog crushed. I remember one time I spoke with disapproval to Zapata. A couple of hours later I noticed I hadn't seen him for quite some time and then realized he was laying down at the far end of the hall (a place he never used) sadly awaiting my decision to recall him from his shame. The shame was mine and henceforth I was much more aware of the power that my word had.
When I first got Zapata, the breeder told me that the day would come when he would test me. He never did, but he sought out some other humans. Curiously enough, this included the breeder! I was walking Z. down the street and saw the breeder talking to the owner of the exotic car dealership and he saw me and called me over. As he talked to the dealer about how wonderful Akitas were he kneeled next to Z. and put his arm over his shoulders in a possessive way. Z first looked at him like "Get your hands off me you idiot" (Akitas are usually poker-faced, but VERY expressive when they wish) but the breeder didn't notice. He began a deep rumble in his chest and still the breeder blathered on. I hesitated, not wanted to embarass the dealer in front of this man whom he obviously was trying to impress. Finally Z rose up and the dealer instinctively did so as well and Z put his paws on the dealers's shoulders and rumbled in his face from about 2 inches away. No teeth bared, no snarl, just a low rumble. After a second, he returned to all fours and ignored the breeder. There was an awkward moment, and we walked on.
Another time, there was a body builder that Z didn't like-- maybe it was the smell of the steroids in his system (but then lots of people didn't like him either) and Z did the same front paws on the shoulders thing and humped him twice to his face before I could say anything. "Z!" I said in a shocked voice, and he got down and, confident of his dominance, ignored the man.
In the previously mentioned incident in which he pinned someone to the wall by the testicles, when I gathered my wits and called him off, his arrogant assurance of dominance was such that he turned his back on the guy, laid down again, and pretended to be asleep.
I tell these stories to give examples of what we might be dealing with. Because Akitas are what they are, the commands which are given should be few and with good reason, but those few given need to be respected.
Before Morro (who was FAR less aggro than Z.) hit puberty, I took him to the dog park everyday with the idea of socializing him as much as possible. (Given the Thosa Mastiff part of Akita lineage, the Akitas are genetically dog agressive) As the juices of adolescence began to hit, his behavior began to change. At 9 months (95 pounds), upon seeing an Irish Wolfhound (170 pounds) that had bullied him elsewhere at 6 months (65 pounds?), he knocked it across the park before I could pull him off the IW which was cringing in fear at the unexpected intensity. Naturally, Morro started feeling pretty cocky and a few days thereafter I saw his body language change towards a large male that had just entered the park. As he headed over, I called him. He heard me but deliberately defied me and continued to head over with what to me was clearly bad intention. So I ran up along side him and picked him up by the scruff of the neck amd the loose skin at the base of the tail and carried him thusly across the park, put his leash on, and took him home. M. was quite respectful for quite some time thereafter.
Because Ryan mentioned his thoughts on dog parks, I go on to mention that the alpha of the park at the time that we went was a three year old Malamute (120ish) who saw in M. a rising challenger to his status. Thus he was always hip checking M. At 11 months of age, M. had enough and put him yelping within 5 seconds of iniitiating his drive. I saw the writing on the wall, and stopped taking him to the dog park. I would say that my experiment in socializing M with puppyhood experience in the dog park was a failure. With Z. I simply knew that the approach of any other male was a fight 100% of the time and acted accordingly. With M, he could lure me into thinking he would behave himself and then start up a fight for no reason I could discern with a dog that wasn't a challenge. BTW, neither one ever hurt the other dog. Z. was a master of dissing the other dog from a distance and provoking it into coming over. Z would either swallow the muzzle on the first move, pin it by the throat or in one case of a dog with a fight collar put it on its back and grabbed it by the testicles
. M. would simply look to pin them down with his chest.
So, in answer to my own question, according to the particulars of the situation:
1) pick up by the scruff of the neck and base of tail (this is very strong and should be used quite sparingly)
2) squeeze the muzzle while looking into the eyes and giving a blow up the nose
3) pin by the neck. This I use with our current dog, a Cairn terrier (don't ask, it is what the children wanted
) when it jumps up on people and ignores command to cease, or when it barks mindlessly from the front deck at passers-by) This has worked very well with lasting effect.
Again, I am not a trainer.
