Well in the interests of opening up the lines of communication and understanding I will take a stab at this topic. I have what could be considered a "big scary dog".

he said that the notion that we must use punishment, especially with larger dogs, is a function of our own need to be in control of the situation - sort of a best defense being a good offense
To a point this could be true. In my case I have been warned and told by many Dogo breeders about what a Dogo is capable of. I have watched video of them on wild boar, I have seen and spoken to people who received grievous injury from a Dogo bite and every single one of the breeders, hunters and owners that I have spoken with have stated that this is a dominant breed that needs lots of socialization and training. If provided with that they are wonderful dogs, if not they can be very difficult. They are not recommended for novice owners. The "need" to control is not about me, it is about Hektor and having him become the dog I wish him to be and making certain he is safe around people, and other animals.

And my immediate ding, ding, ding thought was...isn't that exactly what a leash reactive dog does???? And, we know that most of the time that reaction, with dogs, is based in fear. So, could it be that at some level, those who are so insistent that we use +P are really just making the proverbial pre-emptive strike, lest the big, scary dog really act big and scary? Just as reactive dogs who loosen up and act normally toward other dogs when they are off leash, perhaps humans should consider "dropping the +P" and see that the big dog isn't so scary after all.
Here is where I would break company. I do not consider any of the methods I use with Hektor to be "reactive" ones. I handle him in a very calm manner, if he is disciplined it is with calmness not anger or fear or anything else that could be considered "reactive". I do not fear him, my family does not fear him, but I do respect (and teach my family to respect) the amount of damage he could do, should he ever be so inclined.
Personally I do not see this as having a fear that because my dog is big and scary I must subdue him at all costs, I instead see it as a higher responsibility that I instruct him properly, make sure he is obedient and well behaved and expose him to as many social settings as possible as he grows.

Are you willing to challenge your previously held biases to explore what happens when you are "off leash"?
I am in a constant state of challenging my biases in relation to dog training.

Are we using correction and punishment on larger dogs more than on small ones out of fear, rather than anything else.
No I don't think so. If Gunnar had the personality of Hektor and Hektor had the personality of Gunnar the methods would reverse. It does not matter that Gunnar is not "big and scary".
I cannot speak to the fear, but I can to respect. If more owners had a higher measure of respect for what their large and/or bully breed dogs are capable of perhaps we would have less news reports of attacks. I have yet to see a news report on the "aggressive Chihuahua savages _______ " although I have on one occasion been savaged by a Chihuahua, but I cannot count the times over the years where I have heard news reports, or spoken to friends and family who are amazed that their dog attacked, and in some cases killed a person or another dog. There are breeds that really, truly need the owners to be respectful of what their dog could do given the right situation. Dobermans, Rotts, Filas, Dogos, Akitas, Pits, are just a few.

And, do you believe that big dogs learn any differently than small ones?
No size makes no difference in regards to learning, it is all about personality and to some extent breed. I do not care who says otherwise it is more difficult to train certain breeds than others; if this were not true then you would see a much larger variation in breed when doing competition obedience. Some breeds are bred to be more independent, some are bred to use their nose more and some are bred to work closely with people. Thus a border collie, a dogo, and a bloodhound all trained by the same person using the same methods would all be able to learn, but the border collie would be the one winning the competitions.
I must also say that size also does have some bearing on the minimum amount of training needed to have a dog you can live with. If I am being bitten by an ill behaved, poorly socialized, poorly controlled dog I do hope it is a small breed and not a large one, and I think one can get away with having an ill mannered small breed, where having the same ill mannered large breed will cause you more problems and perhaps hurt some one badly. I can walk a JRT and perhaps live with his pulling on the leash, turn that JRT into and English Mastiff and I am most likely not going to like walking him if he pulls.
