I have always only fed my dogs at night once a day even during season. If you have multiple hunts day after day 8-10 hr days each, would you feed your dogs dogs n morning and night and if you would how much feed would you give them in morning? I have started red cell for my big hunt in 2 weeks. I also feed 31/20 but I want to optimize their energy the best I can. I have always read that dogs digest food longer and therefore feeding needs to be less frequent does that apply when they are using so much energy day after day? Suggestions??
