Purina ONE Plus Large Breed Adult Formula Dry Dog Food
Verified Jun 30, 2026
This is a complete and balanced dry food designed for adult large-breed dogs, with chicken as the primary protein source. It uses a mix of chicken, chicken by-product meal, and plant proteins like corn gluten meal and soybean meal to reach a moderate protein level, with added vitamins, minerals, and glucosamine to support overall health. The calorie density is typical for a dry kibble, making it suitable for maintaining body condition in normally active large dogs when fed appropriately.
This is a solid, middle–to–upper tier large-breed adult formula that should work well for many healthy large dogs. It provides moderate protein and fat levels that are appropriate for adult maintenance, uses chicken as a named primary animal protein, and includes glucosamine for joint support. It’s formulated to meet AAFCO standards for adult maintenance, though dogs with known sensitivities to chicken, wheat, soy, or corn would need a different option.

KibbleLab Review
Strengths
- Chicken as the first ingredient, supported by chicken by-product meal, provides good-quality, highly digestible animal protein for large-breed adults.
- AAFCO complete and balanced for adult maintenance, with reasonable protein (26%) and fat (12%) levels for most adult large-breed dogs.
- Includes glucosamine and omega-6 fatty acids, which can help support joint and skin/coat health in large breeds.
- Contains added vitamins and trace minerals, including vitamin E, vitamin C, zinc, and selenium, to support general health and immune function.
Considerations
- Contains several common allergens, including chicken, wheat, soybean meal, and corn, so it’s not a good fit for dogs with sensitivities to any of these ingredients.
- Relies in part on plant protein sources (corn gluten meal, soybean meal) rather than exclusively animal-based protein, which may be less ideal for very high-activity or working dogs that benefit from higher animal protein levels.
- Glucosamine is present but at a modest level for a dry food; dogs with significant joint disease may still need a separate joint supplement under veterinary guidance.

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
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.
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
Whole Grain Wheat
Whole grain wheat is used in pet foods as a digestible source of carbohydrates, fiber and some plant protein, and provides B‑vitamins and minerals to supply energy and help support stool quality—its nutritional contribution is typically more relevant for dogs than for obligate‑carnivore cats. While whole wheat retains more nutrients and fiber than refined wheat, it is calorie‑dense and can trigger gluten or grain sensitivities in a minority of pets, so animals with known wheat allergies or weight management concerns may be better served by wheat‑free or lower‑carbohydrate options.
