CoQ10: CoQ10 is the last ingredient and is extremely important to the function of organs with a high demand for oxygen, mainly the heart and brain. CoQ10 is normally found in beef heart in the raw diet. Small dogs will receive 30 mg per serving and large dogs will receive 60 mg per serving. CoQ10 has been shown to greatly reduce the incidence of heart disease and improve heart function. It also may help promote healthier gums and protect against periodontal disease. Since 80% of all dogs exhibit some stage of periodontal disease by age 2, this is an extremely beneficial component, but still cannot completely replace tooth brushing. CoQ10 can also help improve renal and immune function.
