In the same way that your stomach is sensitive to certain foods, your dog can develop digestive problems related to food as well. In fact, sensitive stomach, gas, and diarrhea problems are fairly common in dogs – especially dogs fed low-quality dog foods.

So, what can you do if your dog develops stomach issues? The best thing to do is switch to a diet that is gentle on his stomach but still rich in nutrients. Keep reading to learn how.

Why Do Dogs Develop Sensitive Stomach and Diarrhea?

The dog you know and love today is distantly related to the wild wolf. Over thousands of years, wild wolves were domesticated to create what we know of today as “man’s best friend”. Though there are many differences between the dog breeds popular today and the wild wolf, the nutritional needs of domesticated dogs are not too far different from those of their wild ancestors.

Wolves are primarily carnivorous animals in the wild, though they are also scavengers which means that they’ll eat plant foods if nothing else is available. Unfortunately, the commercial dog foods you find on pet store shelves today are hardly natural and many of them contain low-quality ingredients and artificial additives that not only fail to provide nutritional value but can actually irritate your dog’s stomach and digestive system.

In addition to low-quality ingredients irritating your dog’s stomach, dogs have the potential to develop food allergies, sensitivities, and intolerances in the same way that humans can. Food allergies account for about 10% of allergies in dogs and they can develop at any time and for any ingredient. An allergy is an immune reaction in which your dog’s body identifies a certain food as a foreign invader and launches an attack against it, accidentally damaging healthy cells in the process.

Food sensitivities and intolerances are a little different than allergies – they may trigger a digestive or skin reaction, but it generally isn’t an immune reaction. Other possible causes for sensitive stomach, gas, and diarrhea in dogs may include intestinal parasite infections, toxicity from spoiled food or harmful ingredients, and digestive diseases. If your dog suddenly develops symptoms of digestive upset, you should talk to your vet to rule out medical causes.

Can Dog Food Cause Gas in Dogs?

It may be amusing when your dog lets one rip once in a while, but frequent gas could be an indication of an underlying medical problem. In addition to general digestive upset, frequent gas could be a sign of intestinal parasites, pancreatitis, inflammatory bowel disease, exocrine pancreatic insufficiency, or other gastrointestinal infections.

In the absence of an underlying medical condition, frequent gas is often related to food allergies or intolerance – it could also just be a reaction to his diet in general. Ask yourself how often you feed your dog greasy, fatty scraps from the table and whether he has a tendency to get into the trash. If neither of these is the issue, it could simply be that his diet isn’t properly balanced.

The best way to address issues with sensitive stomach, gas, and diarrhea in dogs is to switch him to a limited ingredient diet. A limited ingredient diet is simply a type of dog food made with a low number of main ingredients which makes it easier for your dog’s body to digest and less likely to trigger food allergies and intolerance. You still need to make sure the ingredients included in the food are healthy but reducing the number of ingredients should help.

The Top 10 Ingredients to Avoid in Dog Food

In addition to switching your dog to a limited ingredient formula, you should also pay attention to the specific ingredients in that food. A high-quality dog food will be rich in animal protein, healthy fats, and digestible carbohydrates with vitamins and minerals for nutritional balance.

But what ingredients should you avoid? Here are the top 10 ingredients to avoid in dog food:

  1. Wheat – While whole wheat is a healthy food for humans, dogs have trouble digesting this grain and it offers limited nutritional value – avoid wheat flour and other wheat ingredients.
  2. Gluten – A protein found in wheat, barley, and rye, many dogs are sensitive to gluten, so it is generally best to avoid it if your dog has stomach problems.
  3. BHA/BHT – These chemical preservatives are frequently used in pet food, but they have been linked to numerous health problems so try to avoid them in favor of natural preservatives.
  4. Colors – Artificial colors play no nutritional role in dog food – they simply make the product look more palatable to humans so avoid them in your dog’s food.
  5. Corn Syrup – Human foods are laden with added sugars, but sweeteners have no place in dog food – avoid corn syrup and other sweeteners, particularly artificial sweeteners.
  6. Soy – Soy products can be a good alternative protein source for humans but they are less biologically valuable for dogs than meat proteins and they can cause bloating and gas.
  7. Rendered Fat – Healthy fats like chicken fat and salmon oil are excellent sources of energy and nutrition for dogs but rendered fats like poultry fat and animal fat are low in quality.
  8. Propylene Glycol – An ingredient found in antifreeze, propylene glycol is used to preserve moisture in wet foods, but it has been found to be toxic in high doses.
  9. Animal By-Products – If you’re feeding your dog a high-quality diet, it will be made with whole ingredients and not by-products – by-products are cheap fillers from nondescript sources.
  10. Corn – Like wheat, corn can be a healthy ingredient for humans but, for dogs, it is hard to digest and offers little nutritional value – it can also be used to raise protein content without meat.

Now that you have a better idea what kind of diet is the best for dogs with sensitive stomach, gas, and diarrhea issues, here are some suggestions for good brands to try:

    Hi. My chihuaha mix has been suffering chronice diarrhea for a few weeks now. She has very few teeth so can only eat soft dog food. For about a year she was doing great on the Freshpet dog loaf that needs refrigeration. However, she started rejecting it. (This could be because to save $$ I started freezing sections of the loaf so the whole thing wouldn’t spoil after a week in the fridge. The label says freezing is not recommended.) So I moved on to other dog foods — the Cesar plastic tins, which she loves, Trader Joe’s canned, which she likes, and I’ve also given her chicken and rice which I make myself out of white and brown rice mixed with white meat, nothing more. I’ve been rotating these three options, and the diarrhea persists. Usually a couple of times a month she gets lethargic and doesn’t eat at all, but this has been an issue with her for years. I guess it wouldn’t hurt to take her in for a checkup. But I was wondering if you had soft food suggestions. Thanks much, Dave
