Purina One Plus Small Breed Adult Formula Dry Dog Food
Verified Jun 10, 2026
This is a dry kibble formulated specifically for adult small-breed dogs, with lamb and chicken meal as the primary animal protein sources. It provides relatively high protein and fat to support the higher energy needs of smaller dogs, along with added glucosamine and key vitamins and minerals. The recipe includes several grains and plant proteins to supply additional carbohydrates, fiber, and nutrients.
Overall, this is a well-balanced dry food for healthy adult small-breed dogs that need a higher-energy diet. The protein and fat levels are well suited to small dogs’ faster metabolisms, and it’s fully complete and balanced for adult maintenance. It does contain multiple common protein allergens, so it’s best for dogs without known food sensitivities.

KibbleLab Review
Strengths
- Lamb and chicken meal appear early in the ingredient list, providing good-quality, animal-based protein to support lean muscle in active small dogs.
- Higher protein (28%) and fat (17%) are appropriate for small breeds, which often burn more calories per pound than larger dogs.
- Includes whole grains like corn, wheat, and oatmeal, which offer digestible carbohydrates, fiber, and additional nutrients rather than just acting as fillers.
- Fortified with glucosamine plus a full vitamin and mineral premix, and meets AAFCO standards for complete and balanced adult maintenance nutrition.
Considerations
- Contains multiple common allergens, including chicken, lamb, beef fat, soy, wheat, and corn gluten meal, so it’s not a good choice for dogs with food allergies or sensitivities to these ingredients.
- Relies partly on plant proteins (soybean meal, corn gluten meal), which are nutritionally useful but don’t provide the same amino acid profile as animal protein on their own—though here they are combined with animal sources.
- Calorie density is fairly high at about 406 kcal per cup, so portion control is important for small dogs prone to weight gain.

Top 5 Ingredients Explained
01
Lamb
Lamb is commonly used in dog and cat foods as a high-quality animal protein that supplies essential amino acids, iron and B vitamins and is often chosen for its palatability or as a “novel” protein in elimination diets. It can be higher in fat and calories than some other meats and may still cause allergic reactions in sensitive animals, so owners of overweight pets or those with food sensitivities should consult a veterinarian and use proper handling/cooking practices if feeding raw or homemade lamb.
02
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.
03
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.
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 Corn
Whole grain corn is commonly used as a carbohydrate and energy source in pet foods, providing digestible starch, dietary fiber, some protein, and B vitamins and minerals while retaining more nutrients than refined corn. It is generally economical and well-tolerated by most dogs and many cats, but because cats are obligate carnivores animal-based proteins are nutritionally more important, and pets with grain sensitivities, certain metabolic conditions, or requirements for low-carbohydrate diets may need alternatives; proper sourcing and processing also reduce mycotoxin risk and improve digestibility.
