Ultimate Pet Nutrition

About Ultimate Pet Nutrition 

Ultimate Pet Nutrition is a holistic pet food and supplement brand founded in 2017 by Dr. Gary Richter, DVM, MS, CVC, CVA, in Encino, California. The brand focuses on freeze-dried raw nutrition, veterinarian-developed supplements, and single-ingredient treats for dogs and cats. Dr. Richter, named America's Favorite Veterinarian by the American Veterinary Medical Foundation, built the brand on a simple principle: minimally processed, nutrient-dense food should be accessible to every pet parent. In 2025, actor and health advocate Rob Lowe joined the brand as a partner, helping spread awareness of Ultimate Pet Nutrition dog food and its raw-nutrition philosophy to a wider audience of pet parents.

Frequently Asked Questions About Ultimate Pet Nutrition 

Q1: What is Ultimate Pet Nutrition, and what products does it make?

Ans: Ultimate Pet Nutrition is a holistic pet food and supplement brand founded in 2017 by Dr. Gary Richter, DVM. The brand makes freeze-dried raw dog food under the Nutra Complete line, an all-in-one supplement called Nutra Thrive, single-ingredient freeze-dried treats, air-dried training treats, dental chews, and food boosters for dogs and cats.

Q2: Do I need a prescription to buy Ultimate Pet Nutrition products?

Ans: No prescription is required for any Ultimate Pet Nutrition product. The brand's food, treats, supplements, and dental chews are all over-the-counter products available without veterinary authorization. However, consulting your vet before adding a new supplement is always recommended, especially for dogs with existing medical conditions or current medications.

Q3: What is the difference between Nutra Complete and Nutra Thrive?

Ans: Nutra Complete is a freeze-dried raw meal made with real meat, organ meats, and superfoods that can replace or upgrade your dog’s regular food. Nutra Thrive is a daily powder you mix into food to boost nutrition with vitamins, probiotics, enzymes, and antioxidants.

Q4: How does freeze-drying preserve nutrients in Ultimate Pet Nutrition dog food?

Ans: Freeze-drying removes moisture from raw ingredients at low temperatures without using heat, preserving natural enzymes, antioxidants, and proteins that high-heat cooking would degrade.

Q5: Where can I buy Ultimate Pet Nutrition products online?

Ans: Ultimate Pet Nutrition products are available through HardyPaw, an NABP-authenticated online pet pharmacy. HardyPaw carries the full range of Nutra Complete dog food, Nutra Thrive supplements, Nutra Bites treats, Nutra Minis training treats, Canine Boost booster, and Canine Fresh dental chews, with competitive pricing and delivery across the US.

Q6: Can I use Ultimate Pet Nutrition Nutra Bites treats for training?

Ans: Yes, but the standard Nutra Bites freeze-dried treats are slightly larger and more suited for rewarding. For high-repetition training sessions, Nutra Minis Air-Dried Training Treats (available in beef and chicken) are the better choice. They are smaller in size, lower in calories per piece, and designed specifically for frequent treat-based training.
