Purina OM dog food is for weight management to help overweight dogs safely lose weight. The foods are high in fiber to promote a full feeling after eating. In addition, they contain significant amounts of protein to maintain muscle mass.
Purina OM foods are also used to help adult dogs maintain a healthy weight. Both the dry and canned formulas are low in fat and calories. Dogs with consistent lean body weights have been shown in a long-term Purina study to live longer and develop fewer chronic conditions later than overweight dogs. The primary ingredients of the dry formula come from corn, soybeans and peas. In addition to water, chicken, liver and rice are the main components of the wet food.
