Probiotics, Prebiotics and Postbiotics Explained

Short answer: a probiotic is a dose of live good bacteria for the gut; a prebiotic is the fibre that feeds them; a postbiotic is what those bacteria produce once they've fed. Our 120g pack is a pre + probiotic — 4 billion CFU of good bacteria per scoop plus inulin as their food, not a postbiotic product. It's labelled a dog feed supplement, not a medicine, and it doesn't replace anything your vet has prescribed.

Probiotic, prebiotic, postbiotic — what each word actually means

The three words describe three different stages of the same gut process, and it helps to know which one you're buying.

Term	What it is	What it does
Probiotic	Live, beneficial bacteria	Added to the gut to support a balanced population of microbes
Prebiotic	A type of fibre the body can't digest itself	Feeds the good bacteria already there, and any that are added
Postbiotic	Compounds bacteria leave behind after fermenting that fibre	Byproducts of a healthy gut process, not something you dose directly

Our powder covers the first two: live good bacteria plus the fibre to feed them. It isn't sold or formulated as a postbiotic product.

What's actually in the VitalPaws pack

Every scoop carries 4 billion CFU of good bacteria and inulin — a prebiotic fibre whose only job is to be food for those bacteria so more of them survive the trip through the gut. Alongside that: haldi (turmeric) and black pepper extract — black pepper is there because turmeric absorbs poorly on its own, and coconut oil for its fats. Real freeze-dried chicken liver is in the mix for taste, not as an active ingredient. The pack doesn't name individual bacterial strains. Full ingredient breakdown: why we formulated it this way →

Why it's a feed supplement, not a medicine

VitalPaws Pre + Probiotic is labelled a dog feed supplement. That's a specific category: it supports a dog's day-to-day gut balance alongside a normal diet, and it is not a substitute for veterinary diagnosis or treatment. If your dog is on a vet-prescribed treatment — for infection, allergy, or anything else — keep giving that exactly as directed and mention to your vet that you're adding a pre + probiotic. A gut supplement sits alongside your vet's plan; it is never a substitute for it.

Signs some parents link to gut balance — and what to rule out first

The signs parents most often mention to us when they're weighing whether their dog's gut needs support are scratching, paw licking, a loose or inconsistent potty, gas, bad breath and a dull coat. These may be gut-linked, but each one has other, more urgent explanations that need ruling out first — fleas, mites and other parasites, skin or ear infections, and a recent food change can all cause the same signs. If the skin is broken, there's a strong smell, or your dog is off food or unwell, that's a same-day vet visit, not a supplement question.

Does a healthy dog need one?

Honestly — no, not just because it exists. A healthy dog with a settled gut, a normal appetite and normal stools doesn't need a daily probiotic added on top. Where preventive use is reasonable is around specific gut stressors: alongside a course of antibiotics, a sudden diet change, travel, a boarding stay, or the monsoon, when a dog's gut is more likely to be knocked off balance for a few days. Outside of those windows, a settled, healthy gut is doing its job on its own.

A note on mood

Some parents tell us their dog seems calmer or more settled once its gut and skin issues ease — that's their own observation about their own dog, not a claim we make about what the powder does. We don't market this as a calming or anxiety product.
