Is your dog having continuous episodes of diarrhea? Are you racing back and forth from outside and cleaning up daily piles of vomit? These are all clear signs that your dog may need a dog food formulated for sensitive stomachs.

GI upset like loose stool, flatulence, and vomiting is common occurrences in dogs which could have many causes. Most hospitals go by the general rule that a veterinarian should evaluate them if your dog vomits more than three times in a twenty-four-hour period, stops eating, drinking, or has a persistent loose stool that contains blood. Once your Veterinarian can do a full workup and rule out any underlining conditions, like pancreatitis, or an internal parasite, they might suggest a different diet to help with your dogs’ symptoms. 

Some dogs have a stomach of steel, and others need to be on Sensitive Stomach dog food to support gut health and prevent chronic GI upset. When looking for a diet with limited ingredients, it’s essential to look for a low-fat, high-fiber diet. Prebiotics are also important in dog food. It’s a fiber that doesn’t break down, so the bacteria in your dog’s gut can feed on it, promoting healthy bacteria growth, and firming their stool.

2. Best Prescription Diet: Hill’s Prescription Diet  Z/D Skin/ Food Sensitivities Original Flavor Dry Dog Food 

Hill’s Science Diet Z/D dry food is a hydrolyzed protein diet.

The protein is broken down into smaller, easily digested pieces using the process of hydrolysis. Hydrolysis is when they chemically break down a protein source using enzymes. The food breaks down into smaller particles, so the protein can digest faster without triggering the dog’s immune system as a potential threat. Some dogs cannot eat common proteins found in dog food like chicken, beef, or other forms of poultry.

Z/d is a hypoallergenic food, clinically proven to help dogs with food sensitivities. It contains antioxidants and only one carbohydrate source, corn starch. It also has omega-3 fatty acids that help with arthritis and chronic kidney disease and promote brain and eye development. 

A customer review spoke about her Chihuahua that suffered GI upset and skin allergies. She said her dog’s symptoms went away in days, and he absolutely loves eating his food!

3. Best Wet Food Diet: Hill’s Prescription diet i/d Digestive Care Low Fat Original Flavor Pate Wet Dog Food 

Hill’s i/d wet low-fat diet is an extremely easy-to-digest formula that doesn’t use chicken as its main ingredient. Instead, it uses turkey liver and pork liver as its primary protein source. Even though this is not a hydrolyzed protein, it is suitable for dogs that have difficulty digesting protein. This food has prebiotic fiber, omega-3 fatty acids, and antioxidants. 

Unlike some other products, ginger is one of the ingredients in this dog food. Ginger is a great way to soothe the GI tract. It helps with nausea and, as an added benefit, has anti-inflammatory properties that aid with things like arthritis. 

Many customer reviews on this product were for dogs with GI illnesses like pancreatitis. Due to the food being low fat and easily digested, dogs with ongoing chronic digestive conditions typically are on this food long-term. I/d helps resolve their diarrhea, vomiting, or upset stomach. A few clients said that their dog wasn’t interested in the pate and had to use some of the dry food to mix in to entice them. That was the most common complaint and seemed to be just for picky dogs.

4. Best Budget Friendly Diet: Hill’s Science Diet Adult Perfect Digestion Salmon Dry Dog Food

Like the sensitive stomach and skin diet, this Hill’s science diet is not a prescription food, which means it’s less costly than most of the previously listed diets for sensitive stomachs. In theory, it’s in the same price range as the sensitive skin diet. It deserves the most budget-friendly diet for all of its added value. This diet contains high-quality salmon and ingredients that will assist gut health and normal stool production. 

To help form stool, it contains prebiotics, whole grain oats, and pumpkin. Hill’s Perfect Digestion dry food contains Vitamin C to help boost your pet’s energy and immune system. The antioxidant is also great for reducing inflammation. Vitamin E is in this food as well. Hill’s said that when wild-caught salmon is accessible, they use that in the food as the primary protein source. There are still chicken products in the ingredients. To be safe, you might want to steer clear of this product for pets with chicken food sensitivity. 

You might wonder why this food is not the best overall diet due to its ingredients and affordability? It’s a new product. This food has only been on the market for a little over a year. Customers have left great reviews on this product, but it hasn’t been out as long as some other diets. When reviewing food, it’s helpful to see if a veterinarian suggests it. There are just client reviews, and most of them have discovered it on their own. So far, though, all of the reviews have been great!

Choosing the Best Dog food for Sensitive Stomachs: What to Look for

Feeding a dog with a sensitive stomach can be a lot of trial and error. It’s important to transition them into a diet slowly. Switching diets requires a lot of patience. It doesn’t always have an effect overnight. When looking for a diet, read the ingredients and select a food that has low fat and high fiber content. These diets can be pricey, especially if it requires a prescription. I promise you will save way more money on Vet bills versus the monthly cost of food. Chewy also offers discounts on food when bought in bulk or signed up for auto shipping.

Different Types of Sensitive Stomach Dog Food: Pros and Cons 

There are a lot of misconceptions about feeding dry vs. wet food diets. One is that wet food is worse for your pet’s teeth. Dry or wet food doesn’t have any effect on dental health. 

Wet food for sensitive stomach diets that work for your pet won’t worsen your pet’s diarrhea just because of the moisture. The ingredients in wet food still help gut health and firm stool. 

Dry Dog Food: Pros 

  • Dry dog food is typically more affordable and longer-lasting when opened. 
  • It doesn’t need refrigeration after opening. Most pet shops and websites sell food storage containers to keep kibble fresh. 
  • There is a reduced chance of food building bacteria. 

Dry Dog Food: Cons 

  • In this case, wet Sensitive Stomach diets seem to have more flavor choices. 
  • Dry food can contain fillers and more ingredients than wet food. 
  • It could be harder to eat for seniors or dogs with dental diseases. 

Wet Food: Pros 

  • More enticing for picky eaters
  • Sensitive Stomach diets appear to have more flavor choices and different types like pate, chicken and rice stew, or Chicken Vegetable Stew for I/D food. 
  • Easier to eat for all breeds and ages. 

Wet Food: Cons  

  • It can still contain fillers. 
  • You have to refrigerate once opened. 
  • It is typically more expensive to buy in bulk versus dry food. 
  • You can’t leave it out all day due to bacteria growth. 

Verified Review: User Experience

One of the customer reviews that we have found, Maddie, spoke about her beloved Golden’s struggle with having diarrhea for months. Maddie had put her dog on a bland diet of boiled chicken and rice and was in and out of the Vet’s office, unable to resolve her GI upset. Maddie’s golden became lethargic over time and would sleep all day. She said on the last visit that she had almost reached a sum of over 600 dollars. Her Veterinarian had recommended Hill’s Sensitive Stomach and Skin diet, and within days of starting it, her stool became firm. She was back to her bright and happy Golen self. Maddie wrote, “I will keep her on only Hill’s Diets. For now, it will save me the hefty Vet bills.” 

Hill’s Science Diet Adult Perfect Digestion is nonprescription dog food, that customers rave about. This customer said in their review that they had a year old Goldendoodle who had recurrent loose stool and occasional episodes of vomiting bile. After bringing her to the Veterinarian for a whole workup, to find there was nothing wrong with her dog.

Chassity just needed to find a diet that would work for her. She had tried countless diets, but none worked, and then she stumbled upon Perfect Digestion. Chassity wrote, “My dog absolutely loves this food, and when I say love, I mean she could eat this until the bag is empty if we’d let her! She eats every last kibble and then licks her bowl clean. The best part is she has great poops on this food.” Another customer said they preferred this diet over the Sensitive Stomach Hill’s diet. He said that it worked just as well as the prescription food his dog was on for his chronic stomach issues.

The Top-Rated Hill’s Science Diet Sensitive Stomach Dog Foods Of 2022: Reviewed and Ranked FAQs (Frequently Asked Questions) 

Is grain free better for dogs with sensitive stomachs?

Dogs with sensitive stomachs might have difficulty digesting products like corn and wheat. When looking at food to feed your dog, you should select a product that uses whole grains, oats, or rice instead.

How do I know if my dog has a food intolerance?

Food intolerances can show up in several symptoms. If your dog has displayed reoccurring symptoms of vomiting, diarrhea, or flatulence, it could be due to the food. Bring them to the Veterinarian to rule out underlining conditions, and most times, they will suggest switching foods in addition to treatment. Other intolerance symptoms can be more dermatology-related, like itching, losing hair, chronic ear infections, and chewing paws.

What is the most easily digested protein for dogs?

Chicken and fish are typically the most digestible protein for your dog, but it’s also the most common protein your dog eats. If you have noticed your dog having chronic GI symptoms even after giving the dog a chicken-based sensitive food diet, try a novelty protein like venison or rabbit, or consider a prescription diet like hydrolyzed protein.
