If your dog has a sensitive stomach, you know all too well the struggle of finding the right food. Stomach upset, vomiting, and food avoidance can make choosing the best dog food feel overwhelming. With choices ranging from kibble to wet to fresh to homemade, how is a pet parent supposed to find the best choice for their dog?
We spoke with Dr. Dody, a member of our veterinary team, to look at what “sensitive stomach” really means, what role food may play in the condition, and how different food options can help or even hurt.
What does “sensitive stomach” really mean in dogs?
The term “sensitive stomach” is used to describe a dog with occasional digestive issues. It refers to the symptoms your dog is showing, not their root cause. While sensitive stomach is a common concern for dogs, it can be very frustrating for their pet parents, especially when it’s not clear what’s causing it.
Dogs with sensitive stomachs may have:
- loose stools
- gas or bloating
- occasional vomiting
- decreased appetite or pickiness
Depending on the dog (and the cause), these symptoms may come and go or happen consistently over a period of time.
Common causes of sensitive stomachs
Finding the cause of your dog’s sensitive stomach is critical to relieving the symptoms. While it may take some trial and error along with veterinary support, it’s well worth it to help both you and your pup have a better quality of life.
The most common causes of occasional digestive issues in dogs are:
- Food intolerance. This happens when your dog has difficulty digesting certain ingredients in their food, like specific proteins or additives.
- Allergies. While also often related to specific proteins in your dog’s diet, allergies involve your dog’s immune system and can lead to additional symptoms like itchy skin and hair loss.
- Gut imbalance. The bacteria in the digestive tract, called the microbiome, play a critical role in digestion. If they go out of balance, it can lead to problems with your dog’s digestive health.
- Parasites or stomach bugs. Parasitic, bacterial, or viral infections also can play havoc with your dog’s digestive system.
When to consult a veterinarian
If you ever notice your dog having severe digestive problems (like repeated vomiting, bloody stool, lethargy, pain, or refusal to eat), take them to a veterinarian immediately. These could indicate a medical emergency that needs prompt attention.
If your dog is showing milder and occasional digestive symptoms, it’s still a good idea to have them examined by your veterinarian. Your vet will determine if any medical treatment is needed.
For example, if they determine parasites are the cause, they can provide treatment to eliminate them. Food allergies are another cause of a sensitive stomach that may need medical treatment to control.
Once medical causes are ruled out, it’s time to take a look at the other main factor in helping sensitive stomachs: food.
Why digestion is critical to overall health
Choosing the right food and supporting the digestive system properly can do more than just soothe a sensitive stomach. It can make a meaningful difference in your dog’s overall health and comfort.
As Dr. Dody explains, “When the digestive system is under stress, it doesn’t only affect the gut. It can impact how well nutrients are absorbed and how the body functions as a whole.”
That’s because your dog’s digestive system does much more than break down food. In fact, more than 70% of the immune system is located in the gut, which means digestive health plays a major role in immune function, inflammation levels, and overall wellness.
When the digestive tract becomes inflamed or irritated, the protective barrier of the gut can become compromised. You may have heard this referred to as “leaky gut.”
Essentially, substances that normally stay inside the digestive tract (like partially digested food particles and bacteria) can pass into the bloodstream where they don’t belong. This can contribute to inflammation throughout the body.
Digestive inflammation can also interfere with how effectively your dog absorbs nutrients from their food, making it harder for them to get the nourishment they need even if they’re eating a healthy diet.
How to find the best dog food for sensitive stomachs
When choosing food for a dog with a sensitive stomach, the goal is to reduce stress on their digestive system while supporting their overall gut health.
Dr. Dody’s recommends pet parents look for:
1. Highly digestible, whole-food ingredients
Whole, minimally processed ingredients are generally easier for your dog’s body to recognize and digest. This can help reduce the workload on the digestive system and calm sensitive stomachs.
2. Limited ingredients
Many cases of sensitive stomach are triggered by specific proteins or additives. Simpler recipes with fewer ingredients can make it easier to identify and eliminate these triggers.
Dr. Dody often recommends limiting additives in general, even when a dog has a “normal” digestive system, as they can irritate the stomach and lead to sensitivities over time.
3. No common irritants
Many dogs with sensitive stomachs do better when avoiding food that contain:
- preservatives
- low-quality fillers like refined grain by-products or unnecessary extra starches
- highly processed ingredients
- These all can contribute to irritation or make digestion more difficult.
In addition to these main three areas, there are some additional ingredients that may be beneficial to your dog. While some diets include these ingredients naturally, it may be necessary to add them as a supplement. (NOTE: we always recommend discussing any new supplements with your veterinarian first.)
1. Fiber and prebiotics
Fiber supports healthy stool formation and regular bowel movements, which can be especially helpful for dogs with sensitive stomachs.
Certain types of fiber, often called prebiotic fiber, also help nourish beneficial bacteria in the gut microbiome. As these beneficial bacteria ferment the fiber, they produce compounds called short-chain fatty acids which help calm inflammation in the digestive tract and support the health of your dog’s gut lining.
This is one of the reasons fiber plays such an important role in maintaining digestive balance and overall gut health.
2. Omega-3 fatty acids
Omega-3 fatty acids (most often given to dogs via fish oil) have strong anti-inflammatory properties. This can help calm inflammation in the digestive tract. For dogs with sensitive stomachs, this can soothe irritation and support healing over time.
3. Probiotics
As we mentioned above, a balanced microbiome is essential for healthy digestion. Beneficial bacteria help break down food, support nutrient absorption, and contribute to overall immune and digestive health.
In some cases, probiotics may help replenish beneficial bacteria, especially after digestive upset or antibiotic use. However, probiotics tend to work best when they’re supported by adequate prebiotic fiber, which helps nourish and maintain healthy bacterial populations in the gut.
Fresh food vs. wet vs. kibble: Which Is the best?
Even when we apply Dr. Dody’s recommendations for what to look for in a sensitive stomach dog food, we’re left with some options. Namely, is fresh food, wet food, or kibble the best option?
How processing affects digestibility
The more processed a food is, the more its natural structure changes. Many commercial foods (especially kibble) are processed with high heat. This high-heat processing can affect nutrient availability, digestibility, and enzyme activity.
This isn’t ideal for any dog. But for dogs with sensitive stomachs, this can make their condition worse.
For this reason, Dr. Dody does not recommend kibble and other highly-processed dog foods for dogs with sensitive stomachs.
Benefits of fresh, whole-food diets
Fresh diets are often easier for sensitive dogs to handle because they are less processed and provide their nutrients in a more bioavailable form. They also are not made to be shelf-stable for extended periods of time, so they naturally have fewer additives and preservatives. And finally, they often have fewer ingredients, so it’s easier to avoid those ingredients that affect your dog’s digestive system.
The biggest drawback to fresh diets is their cost, as buying pre-made fresh food can be quite expensive.
To counter this, Dr. Dody recommends cost-effective homemade diets as the best food for dogs with sensitive stomachs.
Why many pet parents turn to homemade diets
Homemade diets give pet parents all the advantages of fresh food at a far lower cost per meal. They also give you full control over the ingredients, which can be especially helpful when trying to avoid specific triggers.
Here are some things to keep in mind when considering a homemade diet for your sensitive stomach dog:
- “Healthy ingredients” do not automatically make a healthy diet. Only use recipes that are vet-formulated and approved to make sure they have everything your dog needs to thrive.
- Dogs require specific levels of vitamins and minerals to thrive. This becomes even more important for dogs with sensitive stomachs, as their digestive issues can interfere with nutrient absorption. That’s why Dr. Dody always recommends adding a professionally formulated vitamin premix to homemade food to ensure nutritional balance.
- Cooking your dog’s food can seem daunting at first. It’s okay to ease into it gradually (and remember that fresh food can be batch made and frozen to make it more convenient). Even if you can’t feed your dog homemade food every day, supplementing your dog’s commercial food with homemade fresh food a few times a week can still offer support and comfort to your dog’s sensitive digestive system.
Conclusion
Finding the best dog food for sensitive stomachs involves finding food made from whole and easily digestible ingredients that also reduces unnecessary additives, supports the gut microbiome, and contains complete and balanced nutrition. All together, this can soothe your dog’s sensitive stomach and create a strong foundation for their long-term health and happiness.
