About Us
The Fittest Pet brings clarity, trust and premium daily nutrition to pet wellbeing.
Founded for more good years together.
The Fittest Pet was created for dog owners who believe their pets deserve more than short-term care. They deserve thoughtful, consistent daily support that helps them feel well, move comfortably, stay bright, and enjoy more quality time with the people who love them.
We are here to bring clarity, trust and premium daily nutrition to pet wellbeing — so caring for your dog’s long-term vitality feels simpler, more responsible and easier to maintain.
Our mission is simple:
To help pet parents support trust, vitality and longevity through science-led daily wellbeing routines designed for the whole dog.
Our Story
The Fittest Pet began with a feeling many devoted dog owners know well.
That quiet thought in the back of your mind:
“My dog seems fine… but what can I do now to help support their wellbeing for the years ahead?”
Most pet parents are already doing their best. They choose good food. They make time for walks. They book the vet appointments. They notice the small changes — a little less bounce, a duller coat, a sensitive stomach, more anxious behaviour, or slower movement after rest.
But the world of pet supplements can quickly become overwhelming.
One product for joints. Another for digestion. Fish oil for coat. A calming chew. Something for energy. Something for ageing. Something else for antioxidants.
Before long, caring proactively can start to feel complicated, expensive and inconsistent.
Our founder saw this problem clearly and believed pet parents deserved a better way: one that was more thoughtful, more transparent and easier to trust.
That belief became The Fittest Pet.
Why We Created The Fittest Pet
We created The Fittest Pet because dogs do not experience wellbeing in separate categories. How they move, digest, settle, maintain skin and coat, produce energy and manage oxidative balance all work together to shape daily quality of life.
Yet many pet products treat these areas as separate problems. We wanted to create a brand that looked at the bigger picture.
A brand built around whole-dog wellbeing. A brand that respected science without overwhelming pet parents. A brand that focused on long-term quality of life, not quick fixes or exaggerated promises. That vision led to BioNAD Longevity+® — our flagship daily soft chew built around a six-pillar framework to support the foundations of canine wellbeing in one simple routine.
Following years of research & development and comprehensive pilot programs, we are now proud to launch BioNAD Longevity+® in 2026, and also proud to flag that it is Australia’s first all-in-one canine longevity chew, addressing six pillars of wellbeing in a single daily soft chew.
The Fittest Pet is founder-led, but not founder-only.
Our founder works closely with a trusted consortium of veterinarians, researchers, formulation specialists and pet health professionals across the USA, the UK, Canada, France, Asia and Australia.
This global collaboration helps guide our approach to:
– Canine-first ingredient selection
– Functional blend design
– Healthy ageing support
– Nutritional formulation logic
– Ingredient compatibility and stability
– Quality and safety considerations
– Responsible daily use
– Evidence-informed product development
Our goal is not to chase trends, make medical promises or create another confusing supplement.
Our goal is to formulate what our team believes to be one of the most thoughtful, comprehensive and trustworthy pet supplements available — built with care, reviewed with discipline, and developed for real dogs living real lives.

Our Philosophy
Everything we do is guided by three core principles.
Trust
Trust is the foundation of pet wellbeing.
Pet parents deserve to understand what they are giving their dogs, why it is included, and how it fits into a responsible daily routine.
That is why we believe in:
– Clear ingredient intent
– Responsible communication
– Quality-focused development
– Transparent education
– No exaggerated medical claims
– No unnecessary complexity
We know that trust is not something a brand can simply claim. It has to be earned through consistency, clarity and care
Vitality
Vitality is not just about more energy.
It is about a dog who is engaged, comfortable, bright, settled and ready to enjoy everyday life.
A dog’s daily wellbeing is shaped by many connected foundations, including:
– Comfortable movement
– Healthy digestion
– Skin and coat condition
– Calm behaviour
– Energy metabolism
– Immune resilience
– Oxidative balance
– Healthy ageing support
We believe dogs deserve support that reflects how connected these systems really are.
Longevity
For us, longevity is not about making unrealistic promises.
It is about supporting quality of life over time.
It is about more comfortable walks, more calm mornings, more shared adventures, more happy routines and more meaningful years together.
Dogs give us their loyalty, joy and unconditional love every day. The least we can do is care for them with the same level of intention.
Our goal is to help pet parents build daily habits that support long-term appreciation for the pets who give us so much.
Why BioNAD Longevity+® Exists
BioNAD Longevity+® was created to solve a real problem for caring dog owners: supplement overwhelm.
Many pet parents want to be proactive, but end up juggling multiple products, measuring powders, hiding capsules, comparing ingredients and wondering whether they are doing enough.
BioNAD Longevity+® was designed to simplify that routine.
It brings together a broad, six-pillar formulation philosophy in one daily soft chew that tastes like a treat and is easy to give consistently.
It is designed to support key foundations of everyday canine wellbeing, including:
– Brain & Calm
– Joint & Mobility
– Energy & Vitality
– Gut & Immune
– Skin & Coat
– Advanced Antioxidants
Because the best wellbeing routine is the one you can actually maintain.
Built for Responsible Pet Parents
The Fittest Pet is for the pet parent who notices.
The one who sees when their dog takes a little longer to get up.
The one who researches ingredients before buying.
The one who wants to support ageing before it becomes a crisis.
The one who wants fewer products, clearer information and more confidence.
The one who knows that ordinary moments with a dog are never really ordinary.
We built this brand for people who want to care deeply, but responsibly.
Not through fear.
Not through pressure.
Not through miracle claims.
But through thoughtful daily support, transparent education and a genuine commitment to better long-term wellbeing.
Our Commitment to Quality
Premium pet care should come with real trust.
That is why BioNAD Longevity+® is developed with a quality-first mindset, including:
– Vet-formulated development
– Science-led formulation logic
– Canine-first ingredient selection
– Stability-focused product design
– Clear ingredient intent
– Batch consistency considerations
– Purpose-led functional blends
– No artificial colours or preservatives
– Responsible claims and plain
– English education
We are committed to creating products that pet parents can understand, dogs can enjoy, and our team can stand behind.
BioNAD Longevity+® is a complementary pet food for dogs, designed to support daily wellbeing as part of a balanced routine. It is not a substitute for veterinary care, and we always encourage pet parents to speak with their veterinarian about individual health concerns.
A Message from Our Founder
The Fittest Pet was created from love, responsibility and respect for the bond we share with our dogs.
As pet owners, we know the quiet wish for more time.
More walks.
More beach days.
More morning greetings. More sofa cuddles. More years of quality life together.
That wish is what drives us.
By working closely with veterinarians, researchers and formulation experts around the world, our goal is to create products that combine scientific thinking with genuine care for animals.
We believe pet wellbeing should be easier to understand, easier to maintain and easier to trust.
Most of all, we believe our dogs deserve to be supported before they slow down, not only after.
That is why we created The Fittest Pet.
For more good days.
For more shared adventures.
For more appreciation of the animals who give us their whole hearts.
