About Dr. Gary Richter, MS, DVM. CVC. CVA

As an expert veterinarian, Dr. Gary Richter has always had a heartfelt drive to help keep animals healthy, and provide the best chances for their happiness. He’s received over 30 awards, certifications, and honors for his work.

In fact, The American Veterinary Medical Foundation awarded Dr. Richter with the title of “America’s Favorite Veterinarian.” Dr. Gary Richter has paved the way for veterinary science and better pet nutrition for over 20 years, and he’s made his discoveries accessible to every pet owner through his bestselling book, The Ultimate Pet Health Guide.

More than his accomplishments, Dr. Richter is generous of heart. He knows that there are dogs and cats worldwide that sit in county animal shelters just waiting to meet their people. Furthermore, he knows that sometimes providing an animal with a loving home can do as much for the provider of that home as it does for the pet.

That’s why he created Ultimate Pet Nutrition®. It’s also why Ultimate Pet Nutrition® is a proud sponsor of Guide Dogs of America, a non-profit organization that breeds, raises, and trains highly skilled assistance dogs.

About Rob Lowe, Chief Pet Advocate

In 2025, Rob joined Ultimate Pet Nutrition as Chief Pet Advocate, bringing his platform and personal commitment to the cause. His goal is simple: help pet parents everywhere give their furry family members the nutrition they need to thrive — and maybe live a few extra happy, healthy years together.
Rob Lowe has spent decades captivating audiences — from his breakout roles in The Outsiders and St. Elmo’s Fire to beloved TV performances in The West Wing and 9-1-1: Lone Star. But off-screen, his greatest role might be as a devoted dog dad to five rescue pups he shares with his wife, Sheryl.

The Lowes have made it their mission to give at-risk shelter dogs a second chance, welcoming them into their home and helping others find loving families. That passion for rescue work sparked a deeper interest in pet longevity — and eventually led Rob to Dr. Gary Richter. Now they’re working together to build a community where every pet has the chance to live their healthiest, happiest life.
