I purchased this product after my vet gave me some for my 11 year old German shepherd who had a cancerous tumor and a section of her intestines removed. She was having a lot of gas and discomfort at the time. Since giving her Gastri-Soothe twice a day, she no longer has gas or is uncomfortable. I have also been giving it to another shepherd who was "burping" a lot. This has now stopped. I shall continue to order this product.
