Best Dog Food for Sensitive Stomachs


There's nothing more frustrating than buying food for your dog that you're sure they'll love and have them eat it eagerly, only to throw up a few minutes later. Worse, what if your dog eats eagerly, then has a potty accident in the house?

Other signs your dog has a sensitive stomach include doggy gas and itchy, red skin or "hot spots." Some dog digestion sensitivity problems come from the same foods that can cause problems with human digestion, like wheat, corn and soy.

Finding the best sensitive stomach dog food that can help combat food sensitivities and allergies, can be a challenge. We looked at some of the most-popular brands of dog food for sensitive stomachs and found the advantages and disadvantages for the five best options.

What Causes Sensitive Stomach in Dogs and How Can Dog Food Help?

The common misperception that dogs can eat anything they want with no stomach problems, from table scraps to candy bars, is just that: a misperception. The American Kennel Club says that dogs with sensitive tummies share the following three symptoms:

  • Loose stools
  • Flatulence (gas)
  • Occasional vomiting

Severe Symptom Warning

If your dog has severe vomiting and diarrhea, take him or her to the veterinarian as quickly as possible: these are acute problems and can be a sign something more serious could be wrong.

When your dog has sensitive stomach, you will see more moderate, occasional symptoms in your dog's stool, or spot other warning signs that something in your dog's diet could be causing a sensitive stomach.

Pica and Other Causes of Occasional Stomach Upset

Los Angeles veterinarian Dr. Patrick Mahaney told Animal Planet that dogs can have stomach problems because they explore the world through their mouths. They can eat non-food items and suffer vomiting, diarrhea and gas.

Eating table scraps and gobbling human food from the trash or unattended plates are other common causes of dog stomach problems.

Pica is the general term for eating non-food items, used by human physicians and veterinarians. Chewing on sticks or eating grass are types of pica.

Your dog may vomit after eating grass, a behavior that has been observed in wild dogs. Some veterinary studies show that about 1 in 4 dogs that regularly eat grass vomit afterward.

Some veterinarians think that pica behaviors could be a sign of nutritional deficiency. Another likely cause of grass-eating or consuming other non-foods is boredom or curiosity.

Some Dogs Tend to Have More Sensitive Stomachs

We found out that some breeds have more sensitive stomachs due to their size, particularly Yorkies and Scottish Terriers. The older a dog gets, the more likely they will be sensitive to the things they eat.

Dogs that gulp a lot of air when they eat can have flatulence, and others are simply eating dry dog food too fast. Dogs with small stomachs for their size (not necessarily only the smallest breeds) can suffer distress when the dry food expands inside their stomach after eating.

Solutions for dogs that gulp too much air include elevated feeders, and exercise after meals. We recommend trying both to see if this problem improves.

Food Intolerances

Just like people, dogs can be intolerant or even allergic to common foods that other animals have no trouble with. The most common canine allergens or sensitivity trigger foods are wheat, soy and corn.

It's no coincidence that dog foods found to cause sensitive stomach often contain wheat, soy and corn, sometimes as the first ingredient. Don't overlook animal protein sources causing stomach upset, either.

Some dogs are sensitive to fish, poultry or specific kinds of meat protein. We recommend eliminating suspected problem foods one at a time to determine if food allergies or sensitivities could be causing your dog's digestive problems.

Sensitive Stomach Can Also Signal Sensitive Skin

Another concern among owners is itchy skin, sometimes with rash and even bleeding. Sensitive skin in dogs is similar to skin sensitivities in humans, and can result from the wrong type of dog food.

Your dog may be showing signs of sensitive stomach and skin, which makes it even more important for you to choose the right kind of food. Sensitive stomach dog food may also come in versions that relieve skin sensitivities.

Look for Complete and Balanced Foods

The AKC says that commercial dog foods can be a good solution for dogs with sensitive stomachs, although some owners are preparing hypoallergenic home cooked meals for their dogs like plain chicken and brown rice. If you don't have time to cook every meal for your dog, the AKC advises you to look for "complete and balanced" commercial food.

The phrase "complete and balanced" means the food includes all essential nutrients needed by your dog. Including all essential nutrients could also help to eliminate problems like pica which can stem from nutritional deficiencies.

Analyze the Food Label

Pet food labels now give you the information you need to thoroughly analyze nutritional content and value. We advise you to read every label completely when selecting the best food for your dog's nutritional needs and sensitive stomach.

Look for foods that have your most-desirable protein and fiber sources, avoiding any potential sensitivity triggers like soy, wheat or corn. You may have to try several different kinds of food before finding one that's the right fit.

Start Slowly With New Food

Changing from one food to another can cause sensitive stomach problems. The AKC advises you to transition your dog slowly from old to new food.

The best method is to change slowly over the course of 10 days to 2 weeks. Mix a small amount of the new food with your dog's old food one day at a time.

The AKC recommends including about 10% new food and 90% old food on the first day, then increasing about 10% more new food one day at a time for about 10 days.

Other Helpful Dietary Tips

In addition to finding the best food for your dog's sensitive stomach, you can try other best-practices recommended by the AKC and Animal Planet. A small amount of canned pumpkin or yogurt mixed in your dog's food can provide easier digestion.

Pumpkin will help your dog's digestion as a neutral fiber that doesn't upset many dogs' stomachs. Yogurt has probiotics that also help digestion in dogs as well as people.

Some probiotics are available which can be sprinkled on your dog's food. Small dogs or those with very small stomachs can be helped simply by moistening dry food, which helps it expand less in small stomachs.

Watch for Serious Health Problems

If you've picked your dog's food carefully and still see problems, your dog could have a more serious illness. Here are some potential problems that can't be solved by sensitive stomach food, and require veterinary treatment:

  • Stomach virus or bacterial infection
  • Fungal infection
  • Parasites like whipworms, tapeworms or roundworms
  • Pancreatitis from eating large amounts of table scraps or trash
  • Intestinal or stomach disorders, stomach ulcers or gastrointestinal tumors
  • Inflammatory bowel disorders (similar to humans)

Things to Look for in Sensitive Stomach Dog Foods

Although there is no hard and fast rule for exactly which foods help dogs with sensitive stomachs, some ingredients are more likely to cause problems than others. Among common proteins, beef and chicken cause more problems than more unusual proteins like salmon and venison.

Grains that cause problems include corn and wheat, similarly to people. Soy is also a sensitivity-causing ingredient.

Look for sensitive stomach foods without grains like corn and wheat. We also suggest you look for foods with less-common primary sources of protein, like venison, bison or duck.

What is a Good Puppy Food for Sensitive Stomachs?

Several puppies may develop sensitive stomachs, and this can make finding food they can tolerate very difficult. There are several signs you can watch for that may indicate that your puppy has a sensitive stomach, and you have to know what they are so you can get them on the correct sensitive stomach puppy food.

Defining Sensitive Stomach in Puppies

Some dogs can handle all different types of food in their diets without an issue and some dogs simply can't without having problems. Things like certain ingredients, eating something out of the ordinary, or something that makes their digestive tract work a little harder is enough to set off a puppy's sensitive stomach.

Sensitive Stomach Signs to Watch For in Puppies

There are a few easy signs that you can look for to indicate if your puppy has a sensitive stomach or not.

  • Vomiting - While your puppy may occasionally vomit, if they begin to do it regularly or become lethargic, you have a huge red flag for sensitive stomach.
  • Constantly Eating Grass - For your puppy, grass is a natural way to help them calm their upset stomachs. If you notice them eating grass after almost every meal, you may want to look at their food.
  • Diarrhea - If your puppy has diarrhea, it's a good idea to look at what you're feeding them, especially if there hasn't been a recent diet change.

What to Look for in a Sensitive Stomach Puppy Food

You want to look for a complete and balanced puppy food because this will help eliminate some of the products or ingredients your puppy could be reacting to. These types of puppy food contain all of the nutrients your growing puppy needs.

You also may want to consider switching the protein source in your puppy's food because some dogs can't digest certain types of proteins very well. Also, your puppy food should contain a lower fat content, no soy or wheat products, a little extra fiber, quality ingredients, and all of the vitamins and minerals they need to support their healthy growth.
