Purina ONE Plus Large Breed Puppy Formula Dry Dog Food
Verified Jun 8, 2026
This is a complete and balanced dry kibble designed specifically for large breed puppies, with nutrition also suitable for adult dogs. It uses chicken, chicken by-product meal, and corn gluten meal as main protein sources, with rice, wheat, and corn providing carbohydrates and added fiber. The formula includes DHA from fish oil for brain and eye development and glucosamine to support growing joints in large breed pups.
Nutritionally, this is a well-designed option for large breed puppies, with appropriate protein, fat, and carefully managed calcium and phosphorus for controlled growth. The inclusion of DHA and omega-6 fats supports developing brains, eyes, skin, and coat. It uses several common protein sources and grains, which work well for many puppies but won’t suit those with chicken, beef, egg, soy, or wheat allergies.

Top 5 Ingredients Explained
01
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.
02
Rice Flour
Rice flour is a finely milled carbohydrate ingredient commonly used in pet foods as a digestible energy source and as a binder or thickener in kibble, treats, and wet food formulations. It is generally well tolerated by dogs and cats and low in fat, but offers limited protein and essential amino acids (so it should complement animal protein sources), can increase dietary glycemic load which may be relevant for diabetic or weight‑management pets, and may carry low levels of inorganic arsenic depending on sourcing and processing.
03
Soybean
Soybean is a common plant-based ingredient in pet foods used as a concentrated protein and fat source (in forms such as soybean meal, soy protein concentrate/isolate, and soybean oil) that supplies essential amino acids, calories, and beneficial polyunsaturated fats. It can be a cost-effective, digestible protein for many dogs but is less ideal as the sole protein for obligate carnivores like cats and may trigger allergies or deliver phytoestrogens and antinutritional factors (e.g., trypsin inhibitors, phytates) that are typically reduced by proper processing, so diets using soy should be balanced and monitored.
04
Corn Gluten
Corn gluten (often listed as corn gluten meal) is a concentrated plant-based protein and kibble-binding ingredient commonly used in dry pet foods to boost protein content, energy density, and help with texture. It provides digestible protein for dogs but is relatively low in essential amino acids like lysine, is not an ideal sole protein source for obligate carnivores such as cats, and can be a sensitivity/allergen for some pets, so it’s best used alongside high-quality animal proteins and complementary ingredients.
05
Chicken By-Product
Chicken by-product is a common protein ingredient in pet foods made from edible parts of the bird not typically consumed by people—such as organs (liver, heart), necks and other tissues—and is used to add protein, flavor and nutrient density. It can provide concentrated protein, essential amino acids, B vitamins and minerals (and may contribute taurine when organ meats are included), but composition and quality vary by source, so pet parents concerned about sourcing, higher ash/fat content or chicken allergies should check the manufacturer’s labeling and quality standards.
