I don't misunderstand the carb loading reason. I disagree with your comparisons. No one insinuated, or claimed that you said that carbs alone are to be relied upon a show. In regards to greyhounds, they need higher carbs. Bulldogs do not. Carb loading isn't needed in dogs if you're able to replenish the carbs to 100% after every work out. Therefore your carb levels are at optimum levels when needed.
