Am sure you must post for a laugh Flatbread, I do love confidence but if you adopt a stance contrary to the best practice espoused by the main UK dog/animal welfare orgs, training methods used by Search and Rescue, the Police, seeing/hearing dogs etc then you can't be so amazed that people are underwhelmed by your energetic rubbishing of the methods, owners and dogs.
I am not a trainer I have pets, usually rescues and I imagine that there is no real difference in the practical approaches of the vast majority of posters and readers of these boards. Reinforce good behaviour whilst being kind and vaguely consistent probably covers what most people do and a reward is a reward whether a stroke, a ball, food or a carefully tilted eyebrow.
Take a pup, do the basics in any fashion and you usually get a decent dog. If you don't you raise your game and train more then you do and unless you are unlucky, meet adverse situations or are particularly inept at dog reading you get a fine dog. Take a bog standard rescue and the same will be true, take the more demanding dogs or dogs used for more demanding purposes and I think you see theory really tested.
There is no huge divide between your dogs or any other normal run of the mill dog, dogs trained through whatever reward don't need the reward once the behaviour is established. Different dogs work for different rewards not all are food, ball or eyebrow orientated.
I use positive methods because I have taken the best advice available and have seen the vast progress made. I have read Caesar and lots of other stuff but only reward based training got the results I needed. My last rescue was fourteen stone, a bite that could enclose my head, immense power and an awful history. It hadn't been socialised or house trained, but it had been hurt, had fits, and was very dog aggressive. Had I snatched the first bone away whilst bollocking the dog I fear we would have ended very badly also stress made him fit which would further increase my chances of getting bitten. I could have tried to pin him down but the best outcome there would have been an inelegant ride round the locality. Anyway this became a dog my toddler could walk, take anything from and who was a big old soppy very well mannered house guest. I don't mean by that he could be enticed off the sofa with an organic ham bone.
Incidentally fivefour I imagine your dog won't necessarily compensate for the missing eye perfectly, the side he can see from is still possibly going to be clumsy if his depth perception is off.
