Purina ONE +Plus Joint Health Formula Dry Dog Food
Verified Jun 11, 2026
This is a complete and balanced dry food for adult dogs that uses chicken as the primary animal protein, supported by grains like wheat, corn, and rice for energy. It includes added fish oil for omega-3s and supplemental glucosamine to help support joint structure and mobility. The nutrient profile is moderate in protein and fat, making it suitable for many adult dogs with everyday activity levels who could benefit from some extra joint support.
Overall, this is a well-formulated adult dry food from a large, reputable manufacturer, with a solid protein level and balanced fat and fiber for most normally active adult dogs. It offers added glucosamine and fish oil, which can be helpful as part of an overall strategy to support joint comfort and mobility. It’s a reasonable option for adult dogs of most breeds that tolerate chicken and grains and don’t need a highly calorie-dense or very high-protein diet.

KibbleLab Review
Strengths
- Chicken and chicken by-product meal provide good-quality, highly usable animal protein, with a respectable 27% protein on an as-fed basis for a dry food.
- Includes added glucosamine and fish oil, which contribute building blocks and omega-3 fatty acids that can support joint health over time.
- Uses a mix of grains (wheat, corn, rice, oatmeal) and soybean meal to provide energy, fiber, and additional protein, creating a balanced overall nutrient profile.
- Complete and balanced to AAFCO standards for adult maintenance, so it can be fed as a sole diet for adult dogs.
Considerations
- Chicken is the main protein source, so this formula is not suitable for dogs with chicken allergies or sensitivities.
- Contains wheat, corn, and soy, which are safe and nutritious for most dogs but may need to be avoided if your dog has a confirmed sensitivity to any of these ingredients.
- Calorie density is moderately high (about 379 kcal per cup), so portion control is important, especially for dogs prone to weight gain or with lower activity levels.

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
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.
05
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.
