Raw whole prey diet includes meaty bones which are a great source of calcium to strengthen teeth. The tearing/chewing motion when eating the bones helps reduce tartar build-up on teeth, plus helps produce gastric juices which further control the tartar and aids digestion. Tartar build-up can cause gum disease, the inflammatory impact of which has been linked to heart disease. You soon notice that bad no longer overpowers you when you get close to your dog or cat, thanks the reduction/ eradication of the gum disease and the improved digestion. The risk of tartar and gum disease is higher for dogs and cats on starchy dry food as unlike humans, they lack the enzyme amylase in their saliva. Amylase starts to break down starch as soon as it enters the human mouth, however in dogs and cats the carbohydrate sugars from the starch remain in the mouth and teeth and fuel bacteria growth, leading to poor dental health and disease.
