Formulated by Dr. Dan Su, board-certified veterinary nutritionist

Bad breath isn't just cosmetic — it usually starts with imbalanced bacteria in the mouth and gut. GutWell Clean Breath was developed with Dr. Dan Su as a triple-biotic formula — prebiotics, probiotics and postbiotics — that rebalances that microbiome to fight bad breath at the source, instead of just masking it.

Why does your dog's breath stink?

Bad breath starts in the gut — not just the mouth.

That fishy, stinky breath is usually a sign of imbalanced bacteria in the mouth and gut, and it often comes with plaque and tartar. Masking it doesn't fix it. Clean Breath targets the root cause so fresh breath actually lasts.

Beyond surface-level freshening

Fresh breath, from the inside out.

🦷

Fresh Breath

Targets the volatile sulfur compounds (VSCs) bacteria produce — the real source of stinky breath.

🦠

Oral Microbiome

Probiotics and postbiotics promote good bacteria in the mouth and gut.

😁

Teeth & Gums

Brown algae and zinc help reduce plaque and tartar for healthier teeth and gums.

🌿

Triple-Biotic Gut Support

Prebiotics, probiotics and postbiotics balance the gut — where fresh breath begins.

The details

What's in the scoop

A clean, minimally-processed powder — a triple-biotic blend of prebiotics, probiotics and postbiotics plus functional ingredients (brown algae, zinc) that target bad breath, plaque and tartar from the gut up. Natural pork flavor, crunchy texture; just scoop onto food.

Why Native Pet

Root-cause fresh breath, not a cover-up

Most breath products — dental chews, water additives, sprays — just mask the smell. Clean Breath is a triple-biotic powder that fixes the bacterial imbalance behind it.
