Ingredients & Standards

Our Ingredient Philosophy

Clean, Purposeful, and
Easy to Understand

We believe a formula should be more than a long label. Every ingredient should have a clear purpose, and every product should be built around a specific wellness goal. We avoid unnecessary fillers and prioritize ingredients from suppliers we trust.

From nature, with purpose

Every Ingredient Has a Reason

We choose ingredients for their role in a specific formula, their sourcing standards, and the value they bring to a dog's everyday wellness routine.

Grass-Fed Beef Bone Broth & Collagen

A Trusted Foundation From American Beef

Our beef bones come from non-GMO American cattle. The resulting bone broth powder provides a savory, palatable foundation used in Simply and select supplement formulas.

Grass-fed
Non-GMO American cattle
No chemical solvents used in dehydration

Certified Organic Herbs

Whole-Plant Botanicals for Targeted Daily Support

Our herbs come from certified organic farms and are selected for specific formula goals. The blends are formulated for dogs with guidance from a canine herbalist.

Certified Organic Mushroom Extracts

Fruiting Bodies Only.
No Mycelium or Fillers.

We use certified organic, 100% fruiting-body mushroom extracts. They are hot-water extracted for better absorption, verified for beta-glucan content, and made without mycelium, starch, grain, or fillers.

Wild-Caught Fish Oil

A Natural Source of
EPA and DHA

Our Omega-3 Fish Oil is made from premium-grade wild-caught anchovies, sardines, herring, and mackerel. It is designed to support skin and coat health while providing nutritional support for joint strength and flexibility.
