What is Petabolix?

Petabolix gives dogs more years by helping you choose their food with confidence.

No two dogs are the same - their diets shouldn't be either. We look at your dog's breed, age, weight and activity, then show you the food options that fit.

Find the Best Food for Your Dog

  • Breed changes what to feed

    Some breeds need more protein. Others need to avoid certain ingredients.

  • Age changes when to switch

    A Labrador won't be fully grown until 18-24 months — a Chihuahua could be there by 10.

  • Neutering changes their needs

    It slows their metabolism and makes them hungrier.

  • Weight is easy to misjudge

    Most owners think their dog is a healthy weight. Their vet often disagrees.

Faqs

Questions pet parents ask

Petabolix is a personalized pet nutrition platform that analyzes your pet’s individual profile—including age, breed, weight, activity level, and allergies—to identify foods and wellness products that best fit your pet’s nutritional needs.

Yep.

Petabolix is brand-neutral. We don’t recommend products simply because they are our own, rank products based on popularity, or promote products because a manufacturer pays us.

Instead, we start with your pet. We evaluate products from many manufacturers and identify options based on your pet’s individual nutritional needs, preferences, and goals.

No. Petabolix is designed to support—not replace—your veterinarian.

Nutrition plays an important role in your pet’s overall health, and we encourage pet owners to discuss nutritional recommendations with their veterinary team, particularly when a pet has a medical condition or other special health needs.

Recommendations are tailored to the information you provide about your pet, including age, breed, weight, activity level, body condition, health concerns, allergies or sensitivities, current diet, and your preferences and goals.

The more complete and accurate your pet’s information is, the more relevant the recommendations can be.

Depending on your pet’s individual needs, recommendations may include complete diets, supplements, treats, dental products, probiotics, joint support, skin and coat products, weight-management products, and digestive health products.

Not necessarily. Most pets have multiple nutritional options that may be a good fit.

Petabolix typically provides several recommendations so you can compare factors such as brand, ingredients, availability, and price while still choosing products that meet your pet’s nutritional needs.

Because a higher price doesn’t necessarily mean better nutrition.

Petabolix focuses on your pet’s individual nutritional needs and the characteristics of each product—not on price, marketing, or brand popularity.

Petabolix evaluates product information against your pet’s individual nutritional needs and other factors in their profile.

Our goal is to identify products that are an appropriate nutritional fit for your pet rather than simply recommending the most popular or heavily marketed products.

We recommend updating your pet’s information whenever something important changes, such as their weight, age, activity level, medications, health status, or nutritional goals.

Keeping your pet’s profile up to date helps ensure recommendations remain relevant.

No. Petabolix does not sell pet food or wellness products.

We help you discover products that may be a good fit for your pet and may provide convenient links to retailers where you can purchase them. Our goal is to help you find the right products for your pet—not to dictate where you buy them.

Yes. We take your privacy seriously. Your information is used to provide personalized recommendations and improve your experience with Petabolix. We do not sell your personal information.

Petabolix evaluates thousands of foods, supplements, and other wellness products from many leading pet brands. Our product database is continually expanding and being updated as products and product information change.

Petabolix was independently developed by pet nutrition professionals and technology specialists with decades of combined experience in companion animal health, nutrition, and technology.

Petabolix is brand-neutral and has never accepted investment from pet food manufacturers.

Yes. Petabolix can help you compare your current diet with recommended alternatives and understand how different products may fit your pet’s specific nutritional needs.

  • Independent and brand-neutral — Recommendations aren’t based on which brands pay us.
  • Personalized to your pet — Recommendations are based on your pet’s individual needs, not generic rankings.
  • Built around nutritional science — We evaluate products based on nutritional considerations and your pet’s specific profile.
  • Developed with nutrition and veterinary expertise — Built by professionals with extensive experience and credentials in companion animal health and nutrition.
  • Thousands of products evaluated — Compare options across many pet food and wellness brands.
