I don't cut out anything. My last work day is the Wednesday before the show, giving my dog 3 days of rest. I stopped giving a full week rest out some time ago as it always caused me more headache than it's worth. The entire thing about B12 and running hot makes no sense whatsoever. Dogs run hot due to the amount of energy they expend. If they're not in the shape to expend that much energy, you get hot. That's why you have to work the shit out of barnstorming dogs or they will work themselves off their feet, thereby putting them in a position to quit.
