Dan, you know as well as i do that a full dog will not perform as well as a empty one , the reason for that is that the canine feels the world through its stomach an not its brain ,the canine feels its way in life , through its gut,,
I agree with you that a full dog will not perfrom like and emptied out dog. And while I will agree that to a very small extent there may be some truth to your theory about them feeling the world through its stomach, its still only a very small part of it. So small as to not be worth talkin about.
