Yes, and it benefits each life stage differently:

Puppies: Supports healthy development and immune foundation.

If they have a heart that beats and a body that moves, they can benefit.

Our chicken chew formula has a naturally savory flavor. The vast majority of dogs take it as a treat, without mixing or hiding.

More Information

Why the Gut Matters More Than You Think

The gut barrier filters threats, absorbs nutrients, and influences everything from daily energy to immune function.

How a One-Cell Wall Protects the Body

A single layer of cells, sealed by tight junctions, decides what makes it through the gut wall and what is kept out of the bloodstream.

What Irritates the Gut Lining

Age, stress, highly processed diets, certain medications, infections, and environmental toxins all chip away at the gut barrier over time.

The Gut-Targeted Peptide That Helps Repair

This gut-targeted peptide supports gut-lining integrity and healthy blood flow, helping gut tissue renew and stay resilient.

Cognitive Support

Omega-3s and natural antioxidants protect brain cells and promote mental sharpness, focus, and a positive mood as dogs age.

Gut & Joint Renewal

A blend of amino acid compounds, glucosamine, chondroitin, and MSM promotes natural repair, flexibility, and comfort.

Total-Body Vitality

Probiotics, taurine, and CoQ10 strengthen the gut, heart, and immune system, building resiliency and whole-body wellness.
