About Nulo Frontrunner High-Meat Grain-Inclusive Kibble for Dogs

The Heart of Frontrunner

Canine legends aren’t born, they’re made. While many brands boost their foods’ protein content with pea protein and potato protein, Nulo believes animal-based proteins have the optimal amino acid profile your dog needs to run at the front of the pack. Give your dog nutrition that nourishes the mind, body and soul for years to come with Frontrunner.

Raising the Bar on What’s in Their Bowl

From their careful selection of ingredients—like protein-rich turkey, lamb, salmon, chicken, beef and duck—to low-glycemic carb source choices like lentils, chickpeas, barley, oat, millet and sweet potatoes, Nulo approaches pet food the way they approach everything: no shortcuts allowed.

(Nu)trition + (Lo)ve

Nutrition and love are at the core of everything Nulo does. That is why they only use the finest ingredients to craft their high-meat, low-carb recipes. So go ahead and show your pet some love with the wholesome nutrition of Nulo foods.

Healthier Together

Since day one, Nulo has been committed to inspiring pet parents to live healthier together with their pets. That starts with nutrition—animal-based proteins for muscle, low carbs for a healthy weight, and probiotics for immune support are just a few of the ways each recipe provides your pet with a healthy start at every meal. So whatever the day brings, from a big stretch to endless fetch, your best friend will be ready!

What’s the Secret? Real Food!

The team at Nulo believes that keeping pets healthy is a way of life. That’s why their formulas are full of everything pets need and nothing they don’t. The secret in every Nulo recipe is real food you can feel good about feeding.

What Makes Nulo Different?

Backed by Science

Created by nutritionists, vets and food formulators who know that cats and dogs are carnivores who thrive on meat.

Animal-Based Proteins

Low in Carbohydrates

These lower carb recipes more closely mimic the ancestral diet of cats and dogs and help pets maintain a healthy weight.

Functional Probiotics

Probiotics with superior survivability help support digestive health and improve nutrient absorption.

Questions & Answers

14 Customer Questions

What size is the kibble. I have small breed dogs with some missing teeth. They would need something pretty small.
Answer by ChewyAug 07, 2020
Three pieces of kibble bunched together are roughly the same size as a penny. Check out the photo below.

Made in USA and are ingredients from USA.
Answer by ChewyFeb 02, 2021
This food is made in the USA. Nulo's meat, poultry, and fish are sourced from North America, with the exception of some of their duck (France), lamb (Australia & New Zealand), and wild-caught fish (regions can vary based on the migratory path of the wild population). Their fruits, vegetables, vitamins, and minerals are sourced in North America as well as regions throughout the world, but are always traced and required to meet strict safety and quality standards. None of Nulo’s ingredients are sourced from China, with the exception of select vitamin supplements that can only be sourced from there.

How much protein comes from meat?
Answer by ChewyAug 28, 2020
For Nulo Frontrunner formulas, 77% of the protein comes from animal sources (meat).

What’s the sodium content?
Answer by ChewyMar 02, 2020
This formula has approximately 0.27% sodium on an as fed basis.

Great overall

My dog was always picky about dog food and I could never get him to eat any. He loves Nulo Ancient Grain! The shipping with Chewy was phenomenal. I ordered in the early afternoon and it was delivered to the house that very next day. No packaging issues at all.

Upset with what happened to my dogs.

My little peakapoo chewed his tail just about off. Itching from this food. My other dog just got the itching really bad and I will not be buying this brand any more going back to Blue.

While searching for a new food for a puppy with a chicken allergy, I came across this brand and was instantly pleased with their ingredients. I decided to try this line out for my 3 year old flat coated retriever and he loves it! He happily chows down at every meal and I’ve seen a big improvement in his coat and stool in a short time. I loved the food I previously fed him, and he never turned his nose up at it, but he never ate it as enthusiastically as he does Nulo. Super happy with Nulo frontrunner for my adult dog and Nulo challenger for my puppy (which I wish chewy carried as well!)

Chicken Meal is a primary ingredient

While it may not catch your eye immediately, this advertised beef, barley, and lamb food actually contains chicken meal. It made my dog have the worst stools and I finally checked the ingredients a bit more thoroughly and noticed that there is chicken meal vs. chicken fat which he can process.
