If you feed your dog a raw diet you may find Dog Rocks less effective. This is due to a raw diet being high in protein which when digested forms nitrates. Dog Rocks work by filtering out nitrates and other impurities from your dog's drinking water; by feeding a raw meat diet the nitrates will still be present in your dog's urine via their diet. Feeding your dog an all raw diet and using Dog Rocks will not cause a problem with your dog, however you may still experience lawn burns and may require a higher dosage.
