Phivo Christodoulou, widely recognised as The Dog Health Guy, is an Australian canine-health educator, entrepreneur, speaker, advocate and co-organiser of Canine Masters. He is the founder of Augustine Approved, one of the world’s first certified organic wholefood canine supplement companies, and has spent more than a decade exploring the role that nutrition, lifestyle and environment play in supporting canine health and wellbeing.

His journey into canine health began in 2010 with a Boxer puppy named Augustine. What started as a personal search for answers quickly evolved into a lifelong passion for canine nutrition, natural health and disease prevention. Since then, Phivo has dedicated his work to challenging the normalisation of chronic disease in modern dogs and encouraging people to think more critically about the information they receive.

Known for his thought-provoking and often unconventional approach to dog health, Phivo combines personal experience, research and real-world observation to help dog owners make more informed decisions. Through articles, podcasts, interviews, social media and live events, he has become one of Australia’s most recognisable voices in natural canine health.

As co-organiser and co-host of Canine Masters, Phivo is passionate about bringing together leading veterinarians, researchers, nutritionists and health professionals from around the world to share ideas, challenge assumptions and advance the conversation around canine health. His mission is simple: to help people ask better questions, remain open-minded and ultimately help dogs live healthier, happier and longer lives.
