The WITHIN story

Why we Created WITHIN.

We believe pets deserve better - better food, better health and ultimately, a better life.

That's why we created WITHIN: natural, science-backed nutrition that combines real ingredients with functional nutrition to support whole-body health. Every recipe is thoughtfully developed to help dogs thrive, because better nutrition should be effective, accessible and never complicated.

Built properly.
Backed by science.
Made for dogs.

We didn't create Within to follow trends. We created it to raise the standard of dog nutrition.

Every recipe starts with real ingredients, is developed by experts, independently veterinary approved, and enhanced with our unique FormulaBiotics™ blend. It's a simple philosophy: better nutrition, made properly.

What makes WITHIN different from other dog food brands?

Within is built around one simple principle: proper science, properly applied.

Our recipes combine high-quality natural ingredients with FormulaBiotics™, a scientifically studied postbiotic designed to support a balanced gut microbiome — the foundation of immunity and vitality.

We work with veterinary and nutrition experts, manufacture to BRC standards, and test ingredients on the way in — not just the finished product.

The result? Food and supplements that are designed for long-term wellness, not just to tick regulatory boxes.

What is FormulaBiotics™?

FormulaBiotics™is Within's proprietary nutritional complex, included in every product across the range. It contains four active components: prebiotics, postbiotics, antioxidants, and a full vitamins and minerals profile. These work together to support gut microbiome balance, immune function, and long-term vitality. The gut microbiome is the foundation of a dog's immune system. Supporting it consistently, through daily nutrition, is the most effective way to support whole-body health over time.

Can I mix wet and dry food together?

Yes, and we actively support it. Mixed feeding combines the hydration benefits of wet food with the convenience and dental benefits of dry kibble. Within wet food and dry food are both nutritionally complete, so they can be combined in any ratio. Our mixed feeding guide is available on each product page and as a standalone guide on site. It covers recommended daily amounts by dog weight, including portion adjustments when mixing.

How do I transition my dog to WITHIN?

Introduce Within gradually over 7 to 10 days. Start by replacing 25% of the current food with Within, increasing every two to three days. A gradual transition allows the gut microbiome time to adjust to the new formulation and significantly reduces the risk of loose stools or digestive upset during the changeover. Dogs with sensitive stomachs or existing digestive conditions may benefit from a slower 14-day transition.

Is WITHIN vet approved?

Yes. Our recipes and supplements are approved by vets and developed alongside expert pet nutritionists to ensure they deliver safe, effective and balanced nutrition for dogs.

Do all WITHIN wet food recipes contain Chicken?

Yes, all of our current wet food recipes contain fresh chicken as a base ingredient. This is a deliberate choice based on both nutrition and sustainability.

Fresh chicken provides highly digestible protein, naturally occurring minerals and valuable connective tissue. By combining chicken with other meat or fish sources across our recipes, we can also provide a broader and more balanced amino acid profile than would typically be achieved from a single protein source alone.

For the vast majority of healthy dogs, feeding a variety of animal proteins can be nutritionally beneficial and reflects the diversity of ingredients found in many high-quality complete diets. While single-protein diets can be important for dogs with confirmed food reactions, allergies or those following an elimination diet, they are not inherently better for healthy dogs.

Our chicken is sourced fresh, giving us excellent traceability and a short supply chain, while helping us make efficient use of high-quality animal ingredients. Together, these choices support both the quality of our food and our approach to sustainability.

We’re still a new and growing brand, and we understand that some dogs have specific dietary requirements. As our range continues to grow, keep an eye out for new recipes and options.
