ABOUT MARROWBONE

Built for Hera and Leto. Made for every dog.

Marrowbone began with a simple question: was I giving my dogs the nutrition they needed? Finding a clear answer was surprisingly difficult. Product labels varied, feeding methods were hard to compare, and nutrition rarely connected with the other things I was watching, like weight, activity and health changes. I wanted a clearer picture of Hera and Leto's everyday care. So I built Marrowbone.

It started with two hungry dogs

Every day, dog owners make decisions about what goes into the bowl. Yet the information behind those decisions is often incomplete, inconsistent or difficult to interpret. Raw food, kibble, wet food, supplements and treats are rarely understood as part of one complete diet. Weight and activity are tracked somewhere else, if at all.

Marrowbone brings those details together. It gives you one place to record meals, explore the available nutritional information and follow changes in your dog’s weight and activity over time. The result is a more useful record of everyday care, and a clearer understanding of the information behind it.

WHY TRACKING HEALTH & NUTRITION MATTERS

Two dogs, two different needs

Two dogs, two different needs

What works well for one dog may not suit another, and what is best for many dogs, may not suit every dog, even within the same household.

USE CASE 1

Hera - finding what worked for her

Hera began with a widely used, high-quality kibble with strong scientific support and broad professional recommendation. Despite its suitability for many dogs, it did not agree with Hera, and we repeatedly observed severe digestive discomfort after eating.

After seeking further opinions from our vet, a qualified trainer and a qualified canine nutritionist, I chose to trial a different feeding approach. Hera responded well to the change immediately. We have continued with that approach for the past three years, with no further health issues except when she is exposed to certain ingredients or products. We monitor her diet and seek professional advice when needed.

We use Marrowbone to keep Hera’s meals, treats and ingredient exposures together in one place, ensuring she gets everything she needs. This helps us maintain a consistent record of her diet and gives us clearer information to discuss with veterinary or nutrition professionals when needed.

USE CASE 2

Leto - looking for patterns over time

Leto’s needs are different, she is a young dog and a different breed. With appropriate professional support, we have been monitoring common breed concerns like recurring ear irritation, as well as some anal-gland discomfort, occasional travel nausea and hormonal imbalances around her seasons. Her diet has been modified by our vet, and includes additional fibre following professional advice.

We use Marrowbone to record her food, fibre sources, treats and everyday care alongside health observations like discomfort or itching. Over time, that history helps us notice possible patterns between feeding and symptoms.


We can also ensure she is getting extra support in her diet, and at the same time comfortably make fewer decisions from memory, while arriving better prepared for future professional conversations.

Different dogs need different records

Different dogs need different records

A diet that works well for many dogs may not suit every individual, and different dogs may have different supplementary needs. Marrowbone does not diagnose a cause or prescribe a diet. It helps owners keep a clearer record of what was fed, what was observed and what changed over time to support health management and everyday care.

These are personal observations about Hera and Leto, not evidence that a particular feeding approach will produce the same outcome for another dog. Discuss dietary changes or health concerns with your vet or a qualified canine nutrition professional.

Our purpose

To help dog owners understand what they feed their dogs and build a clearer picture of their wellbeing over time.

Clarity without false certainty

Not every nutritional value is equally reliable. Marrowbone distinguishes between declared, transcribed and estimated information, and shows when data is unavailable.

Designed around individual dogs

Every dog is different. Marrowbone keeps each dog’s record separate and can be used across different breeds and feeding styles.

Better records support more informed care conversations.

A clear history can help you notice changes, spot patterns and ask more informed questions with veterinary and nutrition professionals.

Insight with every bowl

Marrowbone brings together information from product labels, manufacturers and recognised food-composition references. Because the amount and quality of available information varies, Marrowbone shows where values come from and identifies data that is estimated, incomplete or unavailable. The database continues to grow as products are added, reviewed and corrected. Transparency is not an afterthought. It is central to how Marrowbone is built.

Marrowbone provides general tracking and informational tools. It does not provide veterinary diagnosis or clinical nutrition advice. Individual needs vary; consult your vet or a qualified canine nutrition professional about medical concerns or therapeutic diets.

Independently built, shaped by dog owners

I designed, built and self-funded Marrowbone after struggling to find a clear, connected view of my own dogs’ nutrition, health, weight and activity.

What began with Hera and Leto is now growing with the help of other dog owners, whose experiences continue to improve the product and shape what comes next.
