Rob Lowe Stars as the No. 1 Hollywood Dog Dad Thanks to Ultimate Pet Nutrition

Rob Lowe has inadvertently made a name for himself as the ultimate Hollywood Dog Dad by promoting Ultimate Pet Nutrition, a brand he truly believes in, and my dogs love.

Ultimate Pet Nutrition® proudly announces that renowned actor and lifelong animal lover Rob Lowe has joined the brand as Chief Pet Advocate. Lowe is loving dog dad with 5 furry family members of his own at home.

On the surface, it might look like just another celebrity cashing a check, but Rob Lowe’s partnership with Ultimate Pet Nutrition has a surprisingly specific purpose: he is there to be the brand’s “chief pet advocate,” a sort of star-powered megaphone for better dog food, treats, and supplements.

Rather than founding the company or formulating the products, Lowe’s role is to connect emotionally with pet parents and spotlight the brand’s nutrition-focused mission.​

Ultimate Pet Nutrition was founded in 2017 by veterinarian Dr. Gary Richter, known for combining conventional and holistic medicine. His company focuses on foods, treats, and supplements designed to support longevity and overall wellness, including Nutra Complete freeze‑dried dog food, Nutra Bites treats, and the Nutra Thrive multivitamin powder.​

Lowe stepped into this already established ecosystem as the public face, not the scientist. The brand leans heavily on that dynamic: Richter builds the formulas; Lowe helps persuade you to actually use them on your dog’s bowl and in their treat jar.​

Lowe says he’s involved because he is both a longtime animal lover and a health-conscious public figure. He’s presented as a devoted “dog dad” whose personal passion for wellness naturally extends from his own lifestyle to his pets’ nutrition.​

Another hook is his connection to animal welfare and rescue causes. The company highlights his support for pet-related charities and matches it with its own partnerships and donations to groups such as International Veterinary Outreach and Pets for Vets. The message is: this is not just about selling premium kibble and supplements, but about helping real animals live better lives, from shelter populations to pampered family dogs.​

Lowe’s title with Ultimate Pet Nutrition is “chief pet advocate,” a role created specifically around his strengths. It signals that he is there to champion the needs of pets and the concerns of pet parents, not to run the company day to day.​

In practical terms, that means you won’t find him in a lab tweaking formulas or in a boardroom planning supply-chain logistics. Public information does not show him as a founder, formulator, or operational executive. Instead, he partners with Dr. Richter to tell the story of why nutrition matters, how these products are designed, and what benefits they are meant to deliver.​

What Lowe Actually Does for the Brand

So how is he involved day to day? Most visibly, Lowe appears in advertising and educational content that centers on his life as a dog owner and his belief in feeding pets like family. Campaigns use his presence to make discussions about things like joint health, energy, and digestion feel more approachable and less like a lecture from a supplement label.​

He also works alongside Dr. Richter in messaging around specific product lines. Nutra Complete and Nutra Complete Infusions, for example, are marketed as nutrient-dense dog foods with added ingredients such as glucosamine and chondroitin to support joint health and mobility, and those benefits are often threaded into Lowe’s advocacy narrative.

Lowe’s job is to take the vet-approved science and translate it into relatable stories: more pep in your senior dog’s step, a shinier coat, a companion that stays vibrant for longer.​

It’s certainly helped me. Lowe’s reputation as a prominent Hollywood Dog Dad precedes me in the park. I carry Ultimate Pet Nutrition dog treats with me in the park, and dog walkers are thrilled, rather than cautious, when I offer their dogs a goody.

Where Dog Food and Treats Fit In

All of this plays out across Ultimate Pet Nutrition’s portfolio of dog products. The brand’s dog category revolves around:

• Nutra Complete freeze‑dried dog food, marketed as a high‑protein, nutrient-dense option.​

• Nutra Bites treats, which emphasize simple ingredient lists and minimal processing.​

• Nutra Thrive, a multivitamin and probiotic supplement that’s sprinkled over food to add additional nutrients and support digestion, immunity, and overall health.​

Lowe’s advocacy ties these products together under one story: if you care about your dog the way he cares about his, you should be intentional about what goes into their bowl and treat jar. Meanwhile, Dr. Richter is positioned as the professional authority who stands behind the formulations and clinical rationale for those foods, treats, and supplements.​
