Loose stool & diarrhea in dogs
When every walk becomes a stool check
Was it firmer today? Worse than yesterday? Was it the food? The treat? Stress? Should you change something again—or give it more time?
When loose or frequent stool keeps returning, dog parents quickly become detectives. The problem is trying to solve the pattern from memory.
What loose stool can mean
Frequent, soft, or loose stool is a symptom — not an explanation.
Loose stool can have many possible causes. Food sensitivity and inflammation are two possibilities worth understanding—but they aren't the only ones.
That's why one bad day usually isn't the useful signal. The useful signal is the pattern: how often it happens, what it looks like, and what was going on around it.
The real problem
Stop trying to remember what changed. Start capturing the pattern.
Two weeks later, nobody remembers which treat was new or when the stool actually firmed up. Recording a few simple things as they happen turns a vague impression into something you can look at.
What's worth tracking
- • Stool frequency
- • Stool consistency
- • Gas or digestive discomfort
- • Food and treats
- • Recent changes
- • Itching or skin symptoms
- • Whether symptoms improve and return
The Vetica system
Test. Connect the clues. Take a more focused next step.
1. Tell us what you're seeing
- Loose or frequent stool
- Stool consistency changes
- Gas or digestive discomfort
- Occasional vomiting
- Itching or skin symptoms
2. Add food patterns
- Current food
- Treats
- Recent changes
- Patterns you've noticed
3. Run the Vetica test
- A saliva swab gives you an inflammation-related biomarker result in about 5 minutes.
4. Get the Vetica report
- The Vetica app combines the test result with the symptoms and food patterns you've entered and creates a short report that organizes the information in one place.
The report organizes information — it doesn't determine the cause, tell you which food is responsible, prescribe treatment, or replace veterinary evaluation.

Two examples of what the Vetica app puts together — whether you use one test on its own, or follow the optional 21-day food-change tracking plan.
The most relevant test
Vetica Inflammation Check
Vetica Inflammation Check measures calprotectin, a saliva biomarker associated with inflammation.
The result doesn't tell you the underlying cause of loose stool. It gives you another focused piece of information when digestive symptoms keep returning or are difficult to explain.
If food-related concerns are also prominent, Gluten Response can add a second clue, and the Inflammation + Gluten — 2-Test Kit provides both.
The Vetica report
Your Inflammation Check result, in context
The Vetica app combines the Inflammation Check result with the digestive symptoms and food patterns you've entered and creates a short report that organizes the information in one place.
Instead of saying, “Their stomach has been weird,” bring the pattern with you.
What you do next
What can you do differently with that information?
What can you do with that information? Usually something smaller and more deliberate than a full reset.
Monitor the pattern first
Give it a little time before changing food, if symptoms are mild and improving.
Make one focused dietary change
Change one relevant thing so the result is easier to interpret.
Track stool afterward
Keep logging frequency and consistency after any change.
Watch symptoms together
See whether digestive and skin symptoms move at the same time.
Retest when appropriate
Add another biomarker result over time when it's relevant.
Bring an organized history
Take the report to your veterinarian instead of reconstructing weeks from memory.
No specific change is promised to improve how your dog feels. The goal is to make the next step easier to learn from.
Working with your vet
When to involve your veterinarian
Significant, persistent, or concerning digestive symptoms — ongoing diarrhea, blood in the stool, vomiting, lethargy, or weight loss — may require veterinary evaluation. Not every loose stool is an emergency, but a pattern that isn't resolving deserves professional eyes.
Vetica is a first step at home, not an emergency or acute-care tool. If symptoms continue or worry you, the information you've collected can make that conversation more focused.
