Dogs bring so much joy, loyalty, and love into our lives — but when your furry friend suffers from a sensitive stomach, it can be stressful, messy, and worrisome. Upset tummies in dogs can lead to vomiting, diarrhea, bloating, gas, or even skin irritation, and often the root of the problem lies in the food they’re eating.
In this comprehensive guide, we’ll take you through:
- What causes sensitive stomachs in dogs
- How to identify the symptoms
- Key ingredients to look for (and avoid)
- And a carefully researched list of the 10 best dog foods to soothe and support your dog’s digestion in 2025
What Causes Sensitive Stomachs in Dogs?
Dogs develop digestive sensitivity for a variety of reasons. Some of the most common include:
- Food allergies or intolerances (e.g., chicken, beef, dairy, grains)
- Poor-quality commercial dog foods with artificial fillers, colors, or preservatives
- Sudden diet changes that disrupt gut flora
- Underlying health issues such as pancreatitis, IBS, or infections
- Overfeeding or eating human food scraps
The good news? In most cases, switching to a high-quality, gentle dog food can dramatically improve your pup’s health and happiness.
How to Know If Your Dog Has a Sensitive Stomach
Watch for these common symptoms:
- Frequent vomiting (especially after eating)
- Diarrhea or soft stools
- Excessive gas or bloating
- Lack of appetite or picky eating
- Itchy skin or excessive licking (can be food-related)
- Weight loss or failure to thrive
If your dog is experiencing any of these, it’s time to look at what’s in their bowl.
