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.

Questions & Answers

12 Customer Questions

Is the trout farm raised or wild caught?
Answer by ChewySep 28, 2022
Nulo works tirelessly to source their ingredients through a network of reputable suppliers who take great care in raising or harvesting animals humanely and safely. The chicken, turkey, and duck are raised free to roam about climate-controlled facilities that are designed to keep the birds comfortable and to protect them from predators, disease, and inclement weather. Lamb from Australia and New Zealand is raised on pastures and the fish is wild-caught, with the exception of the Trout, which is farm-raised in freshwater raceways and ponds. Trout raised this way is considered a “Best Choice” by the Monterey Bay Seafood Watch program as many wild trout populations have become endangered. Additionally, the tuna is certified dolphin-safe by standards set by the National Oceanic and Atmospheric Administration

Kibble size?
Answer by ChewyJul 18, 2022
This kibble is triangular in shape and measures approximately 3/8 inch wide.

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

Is the Trout in this recipe the source of the Omega 3?
Answer by ChewyAug 18, 2020
This particular recipe has 1.26% Omega 3's on an as-fed basis and it is sourced from the Trout and Flaxseed.

my dog does not approve of this new flavor

I switched my puppy to this from the salmon & turkey large breed puppy food (which I would definitely recommend! Shiny coat and she loves it). She is not a fan of the turkey, trout and spelt. She just picks at it. I have to add toppers or treats just to get her to eat. I guess I will be switching back to a salmon based adult food for my picky lady..

switched to Nulo after using ToTW for 12 years

We have had 3 rescued Siberian Huskies and our oldest is over 13 years old. I switched her to Nulo Freestyle Senior a few months ago from having her on Taste of the Wild for the last 12 years. I switched her to Nulo after doing my research and wanting a better quality kibble for her and it has great supplements in it for aging dogs. I recently switched our new 3 year old male rescue Siberian Husky to Nulo Frontrunner Trout/Turkey and he has done great on it. I love the back story on this company and appreciate every ingredient.

Picky Corgi Approved

My Corgi is very picky and was never super interested in other kibble brands we tried. She also has a sensitive stomach and often had bowel issues. Nulo changed the game for is, this is the first kibble she has actually enjoyed eating! She now is consistently finishing her meals and has no longer had bowel issues. I love that it has probiotics in it, I think that has really helped her digestive system. I am so happy I decided to try Nulo!

good food but my dog doesn’t care for it

I like nulo as a brand, but unfortunately my dog is not a fan of the food. He won’t eat it on its own and it upset his tummy so we are switching from it

Frontrunner Ancient Grains Turkey, Trout & Spelt Adult Dry Dog Food

I switched over from Royal Canin several months due the availability issues with the product. I had spoke with a Nulo representative via online chat that convinced me that Nulo was the best for my fur babies. I have tried the Senior which they loved, but decided to switch over to something that was not grain free per Vet recommendations. All the Nulo products have worked well. Will continue to purchase the product with grains.

Recommended by Vet

Great transition from former dog food. Recommended by vet because it is higher in good protein for dogs with hyper skin allergies. So far so good and he loves it!! Thank you Chewy!!!
