My dogs have a very boring diet LOL. They get supercoat biscuits in the morning and grain free Earthborn holistic biscuits at night. They have marrow bones or lamb shank bones and chicken necks once every week or so and meat when I sporadically put a sheep in the feezer. They are lean, shiny, healthy and very active working dogs.
Mine dont ever get the opportunity to mutiny over food. They get what they get end of story and they dont seem to complain. Even if I bring out yummy treats when training agility, usually some type of meat or baked liver, to be honest most of them prefer their toys and when training them on sheep they would have no interest in food what so ever.
