Meet the Veterinarian Behind PetGev

Every ingredient, every dose, and every formulation decision is guided by board-certified veterinary expertise and decades of clinical experience.

Dr. Michael Geist, DVM, DACVIM

Head of Science, Board-Certified Veterinary Internal Medicine Specialist

Dr. Michael Geist is a Doctor of Veterinary Medicine and a Diplomate of the American College of Veterinary Internal Medicine, one of the highest credentials a veterinarian can hold. He oversees every aspect of PetGev's formulation, from ingredient selection and dosing to quality standards and ongoing research, with a focus on building a daily supplement that supports the whole animal, not just individual symptoms.

Throughout his career, Dr. Geist has cared for thousands of dogs and cats with chronic illnesses such as kidney disease, liver disease, heart disease, diabetes, gastrointestinal disorders, and cancer. While treating disease is central to his practice, he believes that exceptional veterinary medicine should also focus on preserving health before illness develops. His passion for preventive medicine, evidence-based nutrition, and healthy aging inspired the creation of PetGev.

Why PetGev Exists

A Healthier, Better-Quality Life Starts With PetGev.

Inflammation. Oxidative stress. Joint wear. Metabolic decline. These don't happen suddenly they build quietly, over months and years, long before you ever notice a change.

Most pet supplements wait for problems to appear. PetGev starts before they do.


We focus on proactive, daily support for the biological systems that influence long-term vitality, mobility, cognition, immunity, and cellular health.

A daily routine. Every day. For a healthier, fuller life.

Inside the PetGev Healthy Aging Blend

Healthy aging in dogs means supporting the body as a whole not just one visible area of wellness. PetGev was developed to help support key functions connected to long-term vitality, including immune health, mobility, cognitive function, skin and coat condition, liver health, and overall cellular wellness. By focusing on these foundational systems together, the formula is designed to provide more complete daily support through every stage of life.

This blend reflects a comprehensive wellness approach rooted in the belief that strength, resilience, comfort, and vitality are all connected. The result is a daily formula created to help maintain quality of life and support healthier, more active years ahead.
