Nulo Frontrunner Ancient Grains Puppy Food - High Protein Puppy Kibble

In this review of Nulo Frontrunner Ancient Grains Chicken, Oats, & Turkey puppy food, the bottom line is simple: it is for owners who want a high-protein, meat-forward dry diet that includes low-glycemic ancient grains to support steady energy and growth. The formula delivers a meat-heavy profile with real deboned chicken and turkey, viable probiotics, and DHA for brain development, so the single biggest reason to buy is its combination of high animal-based protein and gentle, grain-inclusive carbohydrates for growing puppies.

Key Features

• High animal protein: The recipe emphasizes real deboned chicken and turkey to provide a meat-forward profile that supports lean muscle and sustained energy.
• Ancient grains: Oats and barley provide low-glycemic, whole-food carbohydrates that help maintain steady energy between meals and support digestion.
• Probiotics and fiber: Live BC30 probiotics plus natural fiber promote gentle digestion and help maintain a developing immune system during growth.
• Brain and heart support: Included DHA and taurine support cognitive development and heart health while omegas-3 and -6 help a healthy coat and skin.
• No certain fillers: The formula avoids corn, potatoes, soy, and legumes and contains no artificial preservatives, which may suit owners avoiding those ingredients.

Who It's For

This kibble suits puppy owners who prioritize high-protein, meat-first nutrition and want whole-food ancient grains rather than high-glycemic starches or pea and potato proteins. It is a good match for mixed- and pure-breed puppies needing growth-focused calories, lean muscle support, and digestive stabilizers like probiotics.

Owners who need a grain-free diet for veterinary reasons, or who have puppies with a known sensitivity to grains, should look elsewhere. Also, if cost is a primary constraint, some customers noted price considerations, so budget-focused buyers may prefer a more economical alternative.

Pros & Cons
