Strong Choice
This adult dry formula provides a solid, well-balanced option for most healthy adult dogs, using lamb and poultry by-product meal alongside grains and plant proteins. The nutrient profile is appropriate for adult maintenance, and the inclusion of prebiotic fiber, omega-6s, glucosamine, and a full vitamin-mineral package is a plus. It’s best suited to dogs without food allergies to lamb, chicken, beef, wheat, corn, or soy.

Strengths
- Lamb is the first ingredient, providing a primary animal protein source many dogs do well on.
- Meets AAFCO standards for adult maintenance based on feeding trials, which is the strongest form of nutritional validation.
- Includes prebiotic chicory root and a fiber level that can help support digestive health.
- Added omega-6 fatty acids, glucosamine, vitamins, and minerals support skin, coat, and joint nutrition.
Considerations
- Contains chicken by-product meal, beef fat, corn, wheat, and soy, which can be triggers for dogs with food allergies or sensitivities.
- Caramel color is nutritionally unnecessary, though generally considered safe.
- The protein comes from a mix of animal and plant sources, which may not suit owners seeking predominantly meat-based diets.
- Glucosamine is present but at a modest level, so it should not be relied on as a primary joint supplement.

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
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
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.
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
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.
