Like Lewis Hamilton, I’m Exploring a Vegan Diet for My Dog – Could It Be the Key to Longevity?

Lewis Hamilton, the Formula 1 champion and vocal advocate for veganism, recently bid farewell to his beloved vegan dog, Roscoe. The English bulldog, who passed away at the age of 12 due to complications from pneumonia, wasn’t just a constant companion at F1 races and a social media star with 1.5 million followers—he was also a trailblazer in canine nutrition. Hamilton had switched Roscoe to a plant-based diet in 2020, citing transformative health benefits. “He’s like a puppy again at nine years old,” Hamilton shared in an Instagram video. Could this unconventional approach to pet nutrition be the secret to a longer, healthier life for dogs?

Here in Malta, where the Mediterranean diet reigns supreme and plant-based eating is gaining momentum, the concept of veganism for pets is bound to spark curiosity—and perhaps a bit of controversy. With Malta's vibrant food scene increasingly embracing sustainability, the idea of extending ethical and health-conscious choices to our furry friends aligns with the island's evolving lifestyle trends. As someone committed to healthy living, I’ve been inspired by Hamilton’s journey to explore a vegan diet for my own dog, Muggles, an 11-year-old Golden Retriever. But is it truly viable for our pets? And, more importantly, can it be done in a way that safeguards their health?

The Rise of Veganism for Dogs: A Personal Journey

Like Hamilton, I’ve adopted a plant-based lifestyle for ethical and environmental reasons. My two children, Lola and Liberty, are both vegetarians, and I’ve found it increasingly difficult to justify feeding Muggles a meat-heavy diet. As a family, we’re focused on health and longevity—values that extend not just to what’s on our plates, but also to what’s in Muggles’ bowl. However, transitioning him to a vegan diet has been a process of trial and error.

Initially, I dived in with homemade meals, blending sweet potatoes, brown rice, sprouted tofu, chia seeds, pumpkin, blueberries, and other nutrient-rich ingredients. I even whipped up vegan dog treats with peanut butter and banana. While Muggles’ coat gleamed and his energy levels seemed to improve, the downside was clear: frequent bathroom trips and a fair share of flatulence. It became evident that I needed expert guidance.

A consultation with a canine nutritionist revealed the complexity of the task. While dogs can thrive on a vegan diet, it must be carefully balanced with essential nutrients like taurine, methionine, and L-carnitine—deficiencies in which could lead to serious health issues like dilated cardiomyopathy (DCM). The advice was clear: never attempt to create a homemade vegan diet without professional input. Instead, opt for a complete, commercially formulated plant-based dog food, and monitor your pet’s health through regular blood tests.

The Science Behind Plant-Based Nutrition for Pets

The debate over vegan diets for dogs often revolves around their nutritional adequacy. A recent study from the University of Nottingham supports the idea that properly formulated plant-based diets can be a healthy alternative to traditional meat-based options. Sally Barker, founder of The Canine Dietitian, agrees. “It’s a good diet for managing health conditions in dogs with food allergies or intolerances,” she explained, while cautioning against homemade versions that lack nutritional balance.

This science-backed approach aligns with Malta’s growing focus on health and sustainability. As more Maltese households embrace plant-based eating, it’s only natural to consider how these choices extend to the four-legged members of the family. With the Mediterranean’s abundant supply of fresh, nutrient-dense ingredients, pet owners in Malta are uniquely positioned to explore ethical and health-conscious options for their pets.

Ethical Eating for the Whole Family

For me, the biggest challenge hasn’t been Muggles’ adjustment—it’s been the peer pressure. Why should my dog be eating better than the rest of us? It’s a fair question, especially in a country like Malta, where the culinary scene offers a wealth of plant-based options for humans. From vegan restaurants in Valletta to health-focused cafes in Sliema, there’s no shortage of inspiration to elevate the whole family’s diet.

In fact, the principles of a well-balanced vegan diet for pets—nutritional adequacy, variety, and sustainability—are equally relevant for humans. Incorporating more plant-based meals at home or dining at one of Malta’s many vegan-friendly establishments not only supports personal health but also aligns with global efforts to reduce environmental impact.

A Thoughtful Transition for Longevity

As I continue Muggles’ journey toward a fully plant-based diet, I’m reminded of the importance of doing so thoughtfully. Regular vet check-ups, blood tests, and a reliance on professionally formulated meals are non-negotiable. My hope is that, like Roscoe, Muggles will enjoy renewed vitality and a longer, healthier life.

For those in Malta considering a similar path, the key takeaway is clear: veganism for pets isn’t a one-size-fits-all solution, but with proper planning and expert guidance, it can be a viable and ethical choice. Whether you’re inspired by Lewis Hamilton or simply seeking ways to integrate healthier habits into your lifestyle, the journey toward plant-based living—both for humans and pets—offers a world of possibilities.

So, next time you’re exploring vegan options at a local eatery or whipping up a healthy Mediterranean-inspired meal at home, consider how those choices might extend beyond your plate. After all, a healthier, happier life is something we all deserve—pets included.
