Agree with skycat, coursing dogs need a 50/50 diet o carbs and protein, brown rice, wholemeal bread and pasta mixed with meat or fish is what I've fed them for long enough and along with plenty of work to keep them fit works fine for me, also like to give them a brekfast during the season consisting of wholemeal porridge and couple times a week add egg whites, not saying this is the best of diets but any dog I've had has done well enough for me on this
