It might be the most underestimated health signal in dogs: digestive issues. A bloated stomach, soft or watery stools, excessive burping, or a rumbling belly after eating. Many owners believe this is just part of life for a dog. But it’s not. And the solution is more often found in the food bowl than you might think.

What is your dog actually telling you?
Digestive problems in dogs are rarely a random occurrence. They are a signal. Your dog cannot tell you that their stomach hurts, but their body does—through their stool, through burping, through a bloated belly, or by moving restlessly after eating.
Do you recognize this in your dog?
Common signals:
- Regularly soft, mushy, or watery stools
- Defecating more than normal, several times a day, in large quantities
- Excessive burping or flatulence after eating
- Visibly bloated or hard stomach
- Rumbling in the belly (audible)
- Reduced appetite, sluggishness after eating, or restlessness after a meal
- Mucus in the stool
If you recognize one or more of these signals, read on. There is a high chance the cause is closer to home than you think.

A dog's gut: carnivore with a short digestive tract
To understand why so many dogs have digestive problems, we need to look at biology. A dog has a relatively short intestine—significantly shorter than that of a human or herbivores—and a stomach pH acidic enough to digest raw meat and bones. The entire system evolved for one thing: efficiently processing animal proteins and fats.
However, most commercial kibble contains 30 to 60% carbohydrates. Think of corn, wheat, rice, and potato. These carbohydrates are necessary to give kibble its shape during the production process (extrusion), not because a dog needs them. And that is exactly where the problem begins.
What carbohydrates do in your dog's gut
When a dog eats carbohydrates they cannot fully digest, they end up in the large intestine. There, they are fermented by gut bacteria. This fermentation produces gases, which explain the flatulence, bloated belly, and burping you see in your dog.
Scientific research shows that dogs on a raw diet exhibit significantly less fermentation in the large intestine than dogs on kibble, and have a more favorable composition of gut flora.
Sandri et al. (2017), BMC Veterinary Research
Furthermore, undigested proteins and carbohydrates from kibble are linked to higher production of branched-chain fatty acids (BCFAs): substances associated with intestinal inflammation that contribute to fecal odor. In other words: both the quantity and the smell of your dog's stool say a lot about how well their gut is processing the food.
What does the research say?
In recent years, more peer-reviewed research has been conducted on the effect of raw versus commercial diets on dog gut health. The results are consistent:
Kibble (extruded kibble) |
Raw food (BARF/raw) |
|---|---|
|
|
A study from Oklahoma State University (2024) examined 55 dogs on raw versus kibble diets and found significantly higher levels of intestinal alkaline phosphatase (IAP) in the raw-fed dogs. IAP is a protective enzyme in the gut associated with lower susceptibility to gastrointestinal inflammatory diseases.
Hiney et al. (2024), Frontiers in Veterinary Science
Give your dog a healthy gut as a foundation.
But my dog has been eating kibble for years, why problems now?
Most dogs build up a certain level of adaptability over time. But that doesn't mean the system is functioning optimally. A disrupted gut flora can lie dormant for years before symptoms become visible. Often, symptoms you consider normal (a little gas, occasionally soft stools) are actually signs of a gut that has to work harder than necessary.
Dogs that received raw food for a long period had a richer and more balanced gut microbiome than dogs on kibble — an effect that was stronger the longer they ate raw.

What actually is a healthy gut for a dog?
A healthy gut is characterized by:
✓ Defecating 1–2 times per day, small quantities
✓ Firm, well-formed stools with little odor
✓ No burping or flatulence after eating
✓ No visibly bloated or hard belly
✓ Good appetite, calm after meals
✓ Clear, active, and energetic behavior
If this is not the case, it is a signal that something is wrong. And in most cases, the solution starts with the food bowl.
How does the transition to raw food work?
Replace a quarter of current food with Wolfork every day; fully transitioned in 4 days:
Day 1: |
|
Day 2: The gut adjusts to the new protein sources. |
|
Day 3: Most dogs already respond visibly better. |
|
Day 4: From now on, your dog enjoys its new food daily—and how they will love it! |
What do owners notice first after switching? Fewer and firmer stools. No more flatulence. A dog that is calm and satisfied after eating. Not because a symptom is suppressed, but because the gut is finally processing what it needs.

Finally: when SHOULD you go to the vet?
In most cases, nutrition is the solution, but not always. Go directly to the vet if your dog has blood in the stool, loses weight significantly, has a fever, vomits severely, or if diarrhea lasts longer than three weeks without improvement. This could indicate parasites, infections, or a more serious intestinal issue that needs veterinary attention.
Is your dog otherwise healthy, but has been struggling with soft stools, gas, or a bloated belly for ages? Then chances are the food is the culprit. In that case, Wolfork is a logical first step.
