My (now elderly) labrador suffered from an attack of bloat and gastric torsion when he was younger and as a consequence has suffered from a sensitive gut with frequent bouts of loose and often bloody poos ever since. This medicine, (Super Tummy Instant) which we call "William's pink medicine" is really like a miracle cure. As soon as he starts with the runs I give him this and every time his motions firm up within 24 to 48 hours. I have been using this for several years now and would not be without a bottle.
