Can’t say I agree that adding tapioca to raw would be a good idea. I wouldn’t reduce the protein content of my dogs’ food, up the carb content and glycemic load to add pre-biotics when there are much more species-appropriate pre-biotics that can be added without altering the protein and carbohydrate content and glycemic load. Chicory root, burdock root, dandelion root and garlic are all pre-biotics. Many can be purchased in concentrated tinctures specifically for pets that add appreciable amounts of pre-biotics to the diet. I’ve used Prebiotic Plus herbal tincture from Animals’ Apawthecary before and I also add minced raw garlic 2 or 3 times a week. With kibble a starch is obviously necessary, so it’s great to use a starch that has some sort of benefit (such as the pre-biotics in tapioca) because you have to have it, but a raw diet gives the opportunity to completely eliminate starches and that (in my opinion) is the beauty of a raw diet and why I think dogs thrive so much more on raw than on kibble.
