It turns out that sharing your home with a dog or cat could mean sharing far more than companionship. Emerging research suggests that people and their pets may also share aspects of their gut microbiomes – the trillions of bacteria, fungi and other microorganisms that play a vital role in everything from digestion and immunity to brain function and overall wellbeing. As scientists uncover more about this fascinating connection, the microbiome is rapidly becoming one of the most exciting frontiers in both human and veterinary health.
As World Microbiome Day on 27 June shines a spotlight on this rapidly evolving field of science, experts say we’re only beginning to understand the profound influence these microscopic communities have on the health of both people and their pets.
“There’s actual research into people who have pets at home and how their gut microbiomes sync with their pets,” says Catherine Day, registered dietitian and author.
“We still have so much to learn about the microbiome, but what we’re discovering is incredibly exciting. If you are a healthy human, your pet is more likely to be healthy, and if your pet is healthy, that often reflects a healthy shared environment. It’s an incredible relationship.”
While researchers are still uncovering exactly how this relationship works, what is already clear is that the microbiome extends far beyond digestive health. Scientists now recognise it as a key player in immune function, metabolism and the gut-brain connection, making it one of the most exciting areas of health research today.
Research also reveals just how responsive the microbiome is to everyday lifestyle choices. Diet, exercise, sleep and stress all influence the balance of microbes in the body, while fibre-rich foods help nourish the beneficial bacteria that support a healthy microbiome.
“There isn’t one miracle food or one miracle supplement that fixes everything,” says Day. “Looking after the microbiome is about taking a holistic approach. It’s about eating a diverse range of fibre-rich foods, moving your body, managing stress and sleeping well.”
While much of the conversation around the microbiome has focused on human health, veterinary nutrition scientists are uncovering many of the same principles in companion animals.
Dr Karien Brink, veterinarian at Hill’s Pet Nutrition, says advances in microbiome science are fundamentally changing the way researchers think about lifelong pet health. “Everything we do is centred on lengthening and strengthening the lives of pets while strengthening the bond between pets and the people who love them,” says Brink.
Hill’s Pet Nutrition is a partner of the One Health Microbiome Resource (OHMR), a collaboration with researchers at the Harvard T.H. Chan School of Public Health that is building one of the world’s most comprehensive reference resources for human and companion animal microbiomes. By bringing together thousands of microbiome samples, research tools and scientific data, the initiative aims to accelerate understanding of how nutrition, disease and the environment influence the health of both pets and people.
“What fascinates me most is that families and their pets actually share aspects of their microbiome,” Brink explains. “We need to look after our own microbiome, but we also need to look after our pets’ microbiomes because it’s influencing the whole household.”
According to Brink, the science is challenging long-held assumptions that nutrition is simply about providing energy. “We now understand that the microbiome influences far more than digestive health,” she says. “It plays an important role in immune health, and we’re learning more about the gut-brain connection in pets, too. Nutrition is one of the most powerful tools we have to support lifelong wellbeing.”
For both experts, World Microbiome Day is a reminder that some of the biggest breakthroughs in health begin with the smallest organisms.
“The microbiome is one of the most exciting areas of health research today,” says Day. “Every year we’re learning more about how these tiny organisms shape our health, often in ways we never imagined.”
As research continues to evolve, one thing is becoming increasingly clear: caring for the invisible ecosystem within may be one of the most powerful ways to support the long-term health of both you and the pet by your side.
