To a large degree, I agree with you Sonny.
These dogs have a tough row to hoe, and it only makes sense to allow them to have the best chance of "digging deep" by having them 1) healthy, 2) at their best weight, and 3) in top condition.
Fatigue is one thing that can really make a dog quit, and it takes a dogman to know the difference between a dog quitting "winded" and a dog being so exhausted and shocky he does not know where he is.
All of these are judgement calls, and (unfortunately) many don't have very good judgement. Just because a dog "can stand" doesn't mean he knows where he is. Just because "5 minutes later" a dog can recognize what is in front of him doesn't mean he could at the moment of release.
I have said many times before that, if you throw any man in a huge vat of water, that man will be forced to tread-water-and-tread-water-and-tread-water ... but at some point he simply will not be able to tread water anymore ... and so he will drown. And the same is true of these dogs and fighting: no animal can physically go on-and-on-and-on forever. At some point they're going to collapse. This doesn't make them "curs" (cowards); it means they have simply run out of gas.
