My 5 year old rescue dog has a very sensitive tummy, I have to be careful not to feed her any wheat, gluten or grains, but occasionally she might find something on a walk (such as a discarded loaf of bread!) and it upsets her digestion. About 2 years ago she had an extremely severe case of colitis and was passing blood, I tried many different things to help her (including a trip to the vet) but the only product that actually solved the problem was maxxidigest plus. Since then I\'ve used it every day to give her digestive system a little extra help, and although she will still find things to eat that she shouldn\'t, her digestive system is much stronger thanks to this amazing product, I\'m delighted to have found it
