Figuring out that your dog has a sensitive stomach is one of the most frustrating processes. Their stomachs are always upset and their intestines are in disarray. Not only is their diarrhea and gas unbearable, but you can probably tell that they are in actual discomfort.
Once you have determined that your dog is dealing with a sensitive stomach, you have to start the arduous process of determining what is triggering the reaction, and what you need to feed them to not cause future upsets. Some of the most common causes of upsets are Gluten, Soy and Corn.
Not to mention, anytime you switch a food, you throw their already sensitive system even further out of whack. Let me just suggest that you make any change in food very, very slowly, and mix the two brands of food together to slowly transition their stomach from one type to the next.
In addition, depending on your dog’s sensitivity, it may take a few weeks on the new food before it clears them up.
The nice thing is that there are several dog foods that are designed specifically for dogs with a sensitive stomach.
