Frequently Asked Questions

Who are the nutrition experts behind Get Joy?
Get Joy's formulations are guided by a team of veterinarians and animal nutrition scientists with decades of combined clinical and research experience — including board-certified veterinarians, a professor emeritus of animal nutrition from a leading research university, and clinicians specializing in gut health, integrative medicine, and canine wellness. They are active contributors to how our products are formulated.
Why does Get Joy work with veterinary experts?
Because we're making health claims, not just food. Gut health is a complex, science-backed domain, and our decisions about ingredients, formulation, and education need to be grounded in real expertise. Our experts ensure what we say about Belly Biotics™, the gut microbiome, and canine nutrition reflects current science — not marketing trends.
What is Dr. Brett Levitzke's role at Get Joy?
Dr. Brett Levitzke, DVM, serves as Co-Chief Veterinarian at Get Joy. He brings extensive clinical experience in companion animal medicine and integrative wellness, and plays a central role in shaping Get Joy's nutritional standards and veterinary guidance.
What is Dr. George Fahey's role at Get Joy?
Dr. George C. Fahey, Jr., PhD, is Professor Emeritus of Animal Nutrition at the University of Illinois Urbana-Champaign and one of the world's leading researchers on dietary fiber, prebiotics, and the canine gut microbiome. As a Scientific Advisor to Get Joy, he provides research oversight for our Belly Biotics™ formulation.
How do your experts influence Get Joy products?
Our expert team is involved at the formulation level — reviewing ingredient selection, validating gut-health claims, and ensuring Belly Biotics™ functions as intended across ingredient combinations and life stages. They also help translate complex nutrition science into practical guidance for dog parents.
Does Get Joy work with registered veterinary nutritionists?
Yes. Get Joy works with credentialed nutrition professionals as part of our product development and review process, so every formulation decision is grounded in evidence and reviewed by qualified experts — not just flavor-tested or trend-chased.
