I have read that the live cultures in yogurt help inhibit the growth of bad bacteria that can cause digestive upset such as loose stools and excessive gas in dogs. Yogurt is easy to digest and soothing on the stomach. Adding a small amount (not more than a tablespoon daily), to their food is supposed to be okay. I have started giving my dog 1 teaspoon in the morning and evening with the meals. I don't even mix it in. I just put in on top of the food. My two little ones are picky eaters. With the little yogurt on top of their food, they usually eat everything. I was wondering if anyone else uses yogurt on their dog's food and if it has been helpful?
