My big dog had the runs for weeks. Lab tests showed nothing. The vet prescribed this to try, suspecting IBS, before going to prednisone. Within days he came right. This is the 2nd bag he's on. It's a great price from and he loves it. He's a big active 10 month old mastiff? shepherd? nutcase cross and has heaps of energy and is in great condition on this diet.

The Gastro Intestinal food is great for my Mastiff/Sharpei cross who has a very sensitive stomach. Our Vet recommended this when she started having problems with food. We have had no problems since we changed over to it and she is happy to eat it twice a day. I tend to add a bit of water to the food at night just to mix it up a bit for her. So glad that I could purchase it at a great price from
