This cake will leave your pooch begging for more. It is made with sweet potatoes, yellow bananas and honey for that sweetened taste. Bananas are good for your pooch as they contain magnesium that promotes bone growth and helps the body produce protein and absorb vitamins. Sweet potatoes are an excellent source of dietary fiber which helps the digestive system function more effectively. When your furry friend eats fiber on a regular basis, it lowers the risk of them suffering heart disease and the risk of certain cancers as well. This cake is packed with vitamin A which is essential for maintaining healthy eyes, muscles, nerves and skin. It’s also rich in vitamin C, which is critical for properly functioning immune system.
