Why Probiotics, Prebiotics & Postbiotics Matter for Your Dog’s Health

Why Biotics Are Having a Moment — and Why Your Dog Deserves the Full Set

If you’ve browsed the supplement aisle (or even your dog’s food label) lately, you’ve probably seen a lot of buzzwords ... especially probiotics, prebiotics, and postbiotics.

But what do these biotics actually do? And more importantly, do dogs really need all of them?

Short answer: yes, especially if you want more than surface-level digestive support.

At PETNUTRA, we believe in working with your dog’s biology — proactive, not reactive care. (Why wait 'til there's a problem—no one likes unscheduled vet visits!)

That’s why we include all three in our G-Loop supplement: pre-, pro-, and postbiotics. When it comes to gut health, synergy matters. So, let's break these down.

First Up: What Are Prebiotics?

Prebiotics are special plant fibers that act as food for the good bacteria living in your dog’s gut.

They don’t do the digesting themselves, but they create the ideal conditions for beneficial microbes to thrive.

We use FOS (fructooligosaccharides) in G-Loop™ — a gentle, plant-based prebiotic that helps fuel a more balanced microbiome.

✔️ Think of it as: prepping the gut garden.

So What About Probiotics?

Probiotics are the live, friendly organisms that help keep your dog’s digestive system running smoothly. They support healthy stool, reduce bloating, and contribute to immune system balance, especially during times of stress or dietary changes.

In G-Loop™, we include S. boulardii, a clinically supported probiotic known for its resilience and digestive benefits.

✔️ Think of it as: planting the seeds.

And Then There’s Postbiotics

Postbiotics are the newest (and most misunderstood) member of the biotic trio, but they’re incredibly powerful. These are the byproducts produced after probiotics do their work: beneficial compounds like short-chain fatty acids, enzymes, and metabolites that help support gut integrity, immune response, and cellular energy.

G-Loop™ includes TRIVANT® yeast, a postbiotic ingredient that delivers consistent, science-backed support without requiring live cultures to survive the gut.

✔️ Think of it as: the harvest — the good stuff that keeps everything flowing.

Why They Work Better Together

You wouldn’t only feed your dog once a week, right?
Then why support just one part of their gut system?

Pre-, pro-, and postbiotics work best as a team — each one reinforcing the next. Together, they help:

Promote a more diverse, resilient microbiome
Support healthy digestion and nutrient absorption
Contribute to immune system function
Keep your dog feeling balanced and regular, day after day

What the Research Says

According to a 2025 consumer survey by Nextin Research, over one-third of dog parents said they feed their dogs food for digestive support, with 19% doing so regularly. Another 19% reported purchasing a food, treat, or supplement specifically for digestion-related needs in the past year. The data also shows rising interest in probiotics as a key driver behind these decisions.

Bottom line? Biotics matter. And full-spectrum biotic support isn’t just “nice to have” — it’s becoming a must-have.

How G-Loop™ Delivers All Three

We didn’t stop at GLP-1 support. We rounded out our daily formula with:

- Prebiotic (FOS): Fuels beneficial gut bacteria

- Probiotic (S. boulardii): Supports digestive harmony

- Postbiotic (TRIVANT® yeast): Supports immune system function and overall gut balance

It’s all about helping your dog feel their best — from the inside out.
