Dogs love to eat and most dogs will scarf down whatever you put in front of them. Unfortunately, your dog’s stomach may not like everything he eats as much as he does. In the same way that humans can be sensitive or allergic to certain foods, so can your dog.
Dog food allergies and sensitivities are more common that you might think. Food allergies account for roughly 10% of all allergies in dogs and they can cause a wide variety of symptoms ranging from gastrointestinal upset to skin problems and chronic ear infections. Dogs can develop allergies to virtually any food ingredient, but the most common dog food allergies are beef, dairy, wheat, eggs, chicken, soy, and pork.
If you suspect that your dog is suffering from a food allergy or sensitivity, you should consult your veterinarian. He will likely suggest an elimination diet in which you start feeding your dog food made with a novel source of protein and carbohydrate – that is, ingredients he hasn’t eaten before. It also helps if the recipe has a limited number of ingredients because it will reduce the potential for a reaction.
To give you a place to start your search for this kind of food, here are our top ten picks for the best dog food for sensitive stomachs:

What Kind of Dog Food is Best for Dogs with Sensitive Stomachs?
If you suspect that your dog is suffering from food allergies or sensitivities, you should change his diet. Dogs can technically develop an allergy to any food ingredient and the longer you feed him a specific ingredient, the higher the risk that he’ll become sensitivity to it.
But what do you do when your dog develops a food allergy or sensitivity?
The first step is to take your dog to the veterinarian to rule out other potential causes for his problem. Dogs react to food allergies and sensitivities in a slightly different way than humans, so if your dog’s symptoms are largely gastrointestinal, it might not be related to his food. In most cases, dogs with food allergies develop chronic skin problems and recurrent ear infections.
If your veterinarian confirms that your dog’s issues are related to his food, the next step is to change what you’re feeding him. The best thing you can do is switch to a limited ingredient diet (LID) made with a novel source of protein and carbohydrate. As was mentioned earlier, a novel ingredient is simply one your dog hasn’t had before.
For example, if you’re currently feeding your dog a chicken- or turkey-based dog food product, you might try switching to one made with fish or lamb. If your dog’s food contains a blend of different proteins, you might need to go with something a little less common like venison or rabbit. For carbohydrates, novel sources may include oatmeal, chickpeas, or sweet potato.
In addition to thinking about the type of ingredients in your dog’s new food, you also have to think about the number of them. The more ingredients there are in your dog’s food, the more potential there is for him to develop a reaction. Limited ingredient diets are made with a lower number of main ingredients than typical dog food for exactly this reason – to reduce the risk of triggering a reaction. These formulas are still supplemented with vitamins, minerals, and other beneficial additives, but the primary ingredients are usually limited to 5 to 10 proteins, carbohydrates, and fats.
Tips for Transitioning Your Dog onto the New Food
Once you’ve chosen a new dog food recipe for your dog, the hard work is over. The next thing you have to do is transition him onto it.
Your dog’s digestive system is already stressed due to the allergy or sensitivity, so you don’t want to make things worse by suddenly changing his diet. Start by mixing 25% of the new food with 75% of your dog’s old food and maintain that for a day or two. It’s normal for your dog to experience a little diarrhea or soft stools during this time, but if your dog develops nausea or vomiting you may want to check with your veterinarian.
After a day or two mixing the new food in at a 1-to-4 ratio, blend 50% of the new food with 50% of the old food for a few days. From there, mix 75% of the new food with 25% of the old food for a few days. As long as your dog’s stomach seems to be settling down, you can then start feeding him 100% of the new food at every meal.
Dogs are creatures of habit so, as much as they may love to eat, some dogs will be picky when it comes to changing their diet.
There are some simple things you can do to make your dog’s new food more appealing such as:
Drizzling the meal with a little chicken or beef broth (as long as your dog isn’t sensitive to these ingredients).
Take some of your dog’s favorite treats and stir them into the mix.
Buy a canned version of the new food and spoon a little of it over top of the dry food.
It may take some time, but your dog will eventually get used to his new diet and you’ll be able to determine whether the switch is beneficial or not. Pay attention to your dog’s digestion on the new diet and monitor him to see if his symptoms start to disappear. It can take up to 12 weeks for an elimination diet to come into full effect, so be patient!
Once your dog’s symptoms are completely resolved, you have a few options.
One option is to simply keep feeding your dog the limited ingredient diet. As long as he isn’t having a reaction and you can afford to keep feeding it, this may be the best way to go.
Another option is to slowly introduce potential allergens (one at a time) until you’ve identified the problem. This is an option if you don’t already know which specific ingredient is the cause for your dog’s symptoms If you go this route, you can choose an affordable dog food free from the offending ingredient once you’ve identified it and then transition your dog onto that.
A Word of Caution
If your veterinarian diagnoses your dog with a food allergy or sensitivity, he may recommend something called a prescription diet. Prescription dog food is simply dog food formulated to address specific health or nutritional needs. Some brands that offer prescription diets include Royal Canin, Purina, and Hill’s Science Diet.
Before you follow your veterinarian’s advice and start feeding your dog one of these products, take a closer look. First and foremost, you’ll notice that prescription diets from these brands are very expensive – comparable to the cost of a traditional adult dog food diet from one of the premium brands. Second, you’ll notice that the ingredients list is full of low-quality ingredients.
Many prescription dog foods are made with corn, wheat, and soy ingredients – things like corn gluten meal or whole grain wheat. Don’t let the words “whole grain” fool you because corn, wheat, and soy-based ingredients are never a good choice for dogs. They are simply not on par with other ingredients in terms of nutritional value and they have a high risk for triggering food allergies and sensitivities on their own.
It is better to choose a high-quality dog food with limited ingredients (particularly ingredients your dog isn’t sensitive to) than to overpay for a prescription diet of lower quality.
