Hey Terry I feed after our hunts and any hunt, I was always told never run a fed dog because their predator drive is greater on an empty belly. I don't know if that is just my uncle's and other old timers ways or if there is something to it but that is what I have always done. It could be the feed you give them but it seem high in require portions and to tell you the truth Red looks pretty good along with the rest of your dogs.
I have heard the same about not feeding the dogs because there ability to hunt goes up because of that old predator instinct to hunt for food. It makes a lot of sense to me but I have noticed over the years that hard hunting dogs start to wear out after a long day and it seems that when I give a 1/2 ration they hunt hard for a longer period of time.
