At Gussy’s Gut, we trust nature’s wisdom. We make fermented superfood supplements to support gut health and keep dogs and cats well—just how nature planned it.
At Gussy’s Gut, we’re on a mission to simplify gut health for dogs and cats with fermented superfood supplements — nature’s original recipe for wellness. Inspired by millions of years of evolution, we’re bringing back what pets have always thrived on, optimized for today’s world.
For millions of years, animals ate fermented foods. They got it from the stomachs of prey they hunted or from bones they buried and dug up later. Gussy’s Gut was created to bring back this natural diet in a simple way for pets today.
The Visionary Veterinarian
Dr. Ian Billinghurst is a vet and farming expert. He wrote four popular books about how pets should eat like they did long ago. He’s known worldwide for saying pets need real food, not what big companies sell. He started the Billinghurst Institute to teach pet owners about healthy diets. From the beginning, he joined Gussy’s Gut to build the first fermented superfood company for pets.
The Dog-Loving Founder
Rob Ryan started his entrepreneurial career at the age of 14. It was in his 40s that he declared the rest of his business life would be in service to dogs. Rob is passionate about regenerative, biodynamic, and organic farming and healthy living. Rob is personally very experienced in the longevity and supplement business He wants every pet to have fermented food that’s easy to use.
Rob met Dr. Billinghurst in 2000 when he brought home his black Labrador puppy, Buddy. Buddy was not well. Rob worked with two of the top vets in the world, Dr. Marty Goldstein and Dr. Bob Goldstein, who told him to work with Dr. Billinghurst and feed raw food. Rob did. In four weeks, Buddy was healthy again. It was a profound change. Twenty years later, Rob and Dr. Billinghurst reunited again to start Gussy’s Gut together.
Why We’re Called Gussy’s Gut
Gussy’s Gut is named after Gusto - Rob’s second black Labrador Retriever. "Gusto" means "zest for life" in Italian, and it fits Gus. One day, Gus got into the kitchen trash and got very sick. He eventually got better, but his gut was injured. Fermented superfoods helped him recover faster than anything else. Rob saw how well it worked and wanted every pet owner to try it. Gus’s face is on our logo.
Rob learned that health starts in the gut. Vets say the gut does more for dogs and cats than anything else. Join us to use nature’s ways and help your pets live with energy.
