Two of my dogs, Zoey and Apollo, were tested through Innovative Pet Lab (IPL) — a company that helps pet parents get ahead of health issues by analyzing gut and immune markers. I chose to test my two healthiest dogs, expecting perfect results.

To my surprise, both tests revealed early signs of Leaky Gut Syndrome.

This experience reminded me that “healthy” on the outside doesn’t always mean “healthy” on the inside — and that regular testing can be one of the best tools for prevention.

If you’ve discovered Innovated Pet Lab testing kits at your nearly Costco, this article may help you decide if this test is right for your dog.

What is Innovative Pet Lab?

Innovative Pet Lab offers testing kits for pet owners and pet professionals that are peer-reviewed and scientifically proven tools that help identify the cause of intestial and automimmune issues before they develop into more serious conditions.

In other words, IPL helps pet parents to be proactive instead of reactive about their dog’s health, by catching potential problems early — long before their dog shows symptoms.

Their at-home stool tests measure markers that can reveal how well your dog digests food, detoxifies, and maintains a healthy gut barrier.

Currently, IPL offers four types of tests:

  1. Digestion & Detox – Evaluates digestion efficiency, pancreatic function, and detox pathways.

  2. Leaky Gut – Measures how “sealed” the gut lining is, detecting whether toxins or bacteria might be slipping through.

  3. Inflammation & Immunity – Examines levels of gut inflammation, immune function, and the balance of beneficial bacteria.

  4. Comprehensive Review – Combines all three tests for a full picture of your dog’s gut health.

I received two Comprehensive Review tests in exchange for providing feedback on the process and results.

My Experience with Innovative Pet Lab

When I first received the test results, I’ll admit I was disappointed. The initial reports were short on detail, and I didn’t know what to do with the information.

But once I spoke directly with the IPL team, my perspective changed completely.

They were open to feedback, patient in answering my questions, and genuinely interested in improving their reports for pet parents. Since my first test, IPL has expanded the reports, simplified explanations, and even lowered prices, making the investment well worth it.

What the Tests Revealed

Zoey’s Results

Zoey’s test showed low Secretory IgA (sIgA) — the gut’s first line of immune defense.
Low sIgA can mean the immune system is underactive, leaving the body vulnerable to harmful bacteria, toxins, or allergens.

To support Zoey’s gut lining and immune system, I’ve focused on whole-food supplements that nourish her microbiome and reduce inflammation.

Apollo’s Results

Apollo’s results were more complex. His Secretory IgA was slightly elevated, which may indicate mild inflammation or a temporary immune response.

He also had high Zonulin, a protein responsible for keeping the gut lining tight and sealed. Elevated Zonulin suggests that the intestinal barrier is becoming “leaky” — meaning toxins or undigested food particles could be entering the bloodstream.

That’s when I realized: both of my “healthy” dogs had early signs of Leaky Gut Syndrome.

What is Leaky Gut Syndrome in Dogs?

A healthy intestinal wall should act like a fine cheesecloth, allowing nutrients to pass through while blocking toxins and bacteria.

When the gut becomes damaged, the “holes” in that cheesecloth widen. This allows unwanted substances — like undigested food, bacteria, and heavy metals — to leak into the bloodstream, triggering inflammation and immune reactions throughout the body.

What Causes Leaky Gut in Dogs?

Leaky gut develops gradually and can be caused by multiple lifestyle and environmental factors, including:

  • Processed diets or food containing fillers, pesticides, or inflammatory ingredients

  • Chronic stress (yes, dogs experience stress too!)

  • Overuse of antibiotics or vaccines, which disrupt the microbiome

  • Environmental toxins — lawn chemicals, cleaning products, or tap water contaminants

  • An imbalanced gut microbiome, especially after illness or medication

Once this barrier is compromised, the immune system can go into overdrive — leading to chronic inflammation, allergies, and even autoimmune conditions.

Signs of Leaky Gut Syndrome in Dogs

Leaky gut can manifest differently in each dog, but some common signs include:

  • Gas, bloating, or soft stool

  • Recurring diarrhea or vomiting

  • Food sensitivities or allergies

  • Chronic ear infections

  • Skin problems (itchiness, rashes, hotspots)

  • Joint stiffness or arthritis

  • Low energy or behavioral changes

If your dog has recurring symptoms that seem “unrelated,” the gut may be the root cause.

How to Test for Leaky Gut

You can work with your veterinarian to order specific tests, or you can use an at-home kit like Innovative Pet Lab’s Leaky Gut Test.

The process is simple: collect a stool sample, mail it in, and receive results within a few weeks.

IPL vs. AnimalBiome:

  • AnimalBiome analyzes the population of gut bacteria (who’s living there).

  • Innovative Pet Lab looks at gut function and integrity (how well that community is working).

For the most complete picture, some pet parents choose to use both.

Healing and Preventing Leaky Gut in Dogs

After reviewing Zoey and Apollo’s results, my goal became clear: strengthen their gut lining and microbiome.

I’ve learned from experience — my dog Rodrigo lived ten years beyond his original prognosis after we focused on rebuilding his gut health.

The following covers what worked (and continues to work) for my dogs.

My Favorite Gut Health Supplements for Dogs

You don’t need all of these — start with one or two and observe how your dog responds.

An organic blend of fermented, freeze-dried vegetables, fruits, and seeds.
Supports digestion, detoxification, immune balance, and a healthy gut microbiome.
Budget option: Gussy’s Gut Youthful Grasses & Sprouts – made with four grasses and three sprouts for gentle gut support.

A mushroom-based supplement featuring reishi, turkey tail, maitake, shiitake, and Chaga mushrooms — plus probiotics and herbs.
Promotes immunity, heart health, weight balance, and overall vitality.

A humic extract that delivers nutrients efficiently and removes toxins from the gut.
Helps strengthen the intestinal barrier and reduce inflammation.

A blend of anti-inflammatory herbs, probiotics, and prebiotics that calm the digestive tract, fight yeast, and restore gut lining integrity.

A high-quality probiotic and prebiotic formula that includes fulvic and humic acid — perfect for rebuilding gut health after antibiotics.

My Final Thoughts

Testing Zoey and Apollo through Innovative Pet Lab gave me valuable insight into their internal health. It was a reminder that prevention isn’t just about what we can see — it’s about what’s happening inside their bodies.

Gut health is the foundation of total wellness.
When we support digestion, nutrient absorption, and immune balance, we’re not just treating symptoms — we’re protecting our dogs for the long term.

If your dog struggles with allergies, digestive issues, or chronic inflammation, or if you simply want to be proactive, consider starting with a gut health test.
It’s one of the best investments you can make in your dog’s future.
