Over 50% of a dog’s immune system is found throughout the small and large intestine and contains the largest volume of lymphoid tissue in the entire body. Known as GALT (gut-associated lymphoid tissue) this amazing system filters and removes mal-digested feed material, debris, waste products and toxins – all of which are often too large to be removed by the blood stream. GALT also helps to absorb fluids and fats and transport proteins. The intestinal lymph produces antibodies and stores important white blood cells to attack foreign invaders, foreign proteins and pathogens. The small intestine itself houses the Peyer’s Patches which are small masses of lymphatic tissue containing hundreds of lymph nodes found throughout the ileum. They produce lymphocytes and form an important part of the immune system by monitoring intestinal bacteria populations and preventing the growth of pathogenic bacteria in the intestines. Considering the volume of digestive waste that must be processed and detoxified in the intestines every day the optimum function of GALT is not only critical to digestive health but to the health of every other body system and their diseases. Thus the intestinal immune system must be supported with a healthy diet and regular cleansing. Combine the Riva’s Pro-Dygest (Bentonite Clay, Irish Moss, Papaya Leaf, Slippery Elm) with Pro-Colon probiotics to detoxify and cleanse the intestines and to restore and strengthen their immune system.
