8.7 out of 10

Strong Choice

This is a well-formulated functional treat for adult dogs that offers more nutritional value than many standard biscuits. It uses chicken meal as a concentrated protein source and includes vitamin E and other added vitamins to support overall health. It’s best used in moderation as a complement to a balanced dog food, especially for dogs that tolerate chicken and wheat well.

Nutritional Perspective

KibbleLab Review

Strengths

  • Chicken meal as the first ingredient provides a concentrated, high-quality protein source for a treat.
  • Relatively high protein and moderate fat levels for a snack help it fit better into an active dog’s diet.
  • Added vitamin E and other vitamins and minerals can support overall health, including immune function.
  • Each treat is under 3 calories, which makes it easier to use frequently without overfeeding.

Considerations

  • Contains chicken, which will not be suitable for dogs with chicken allergies or sensitivities.
  • Includes wheat ingredients, so it may not work for dogs that need a wheat-free or gluten-free diet.
  • This is a treat, not a complete diet, so it should not replace a balanced dog food.
  • Animal fat and animal plasma are nutritious, but the specific source species are not identified, which could matter for dogs with multiple protein 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
Brewer's Rice
Brewer’s rice is a milling byproduct of rice processing made up of small broken white rice kernels commonly used in pet foods as a highly digestible carbohydrate source, filler and binder that provides readily available energy for dogs and cats while contributing little protein, fat or fiber. It is generally gentle on the stomach and cost‑effective, but diets using it must supply other ingredients for essential nutrients; pet owners should note its relatively high glycemic load (relevant for weight or diabetic pets), the potential for trace environmental contaminants associated with rice, and not confuse it with brewer’s yeast.
03
Whole Wheat
Whole wheat is used primarily as a carbohydrate and fiber source in pet foods, offering energy, some plant-based protein, B vitamins and minerals and more fiber and nutrients than refined wheat. It can aid digestion and satiety—particularly in dogs—but is not essential for obligate carnivores like cats and may cause allergic or gluten-sensitive reactions in some pets, so it should be avoided in animals with known wheat intolerance, certain metabolic conditions (e.g., obesity, diabetes) or specific dietary restrictions.
04
Animal Fat
Animal fat is used in pet foods as a concentrated energy source and palatability enhancer, and can provide fat-soluble vitamin absorption and essential fatty acids (including arachidonic and linoleic acids, depending on the source) that support skin, coat and overall cellular function—particularly important for obligate carnivores like cats. Because it is calorie-dense and prone to oxidation, fats are typically rendered and stabilized; owners should be aware that high-fat diets can contribute to obesity and may trigger pancreatitis in susceptible dogs, so quality, source, and total dietary fat should be considered.
05
Mixed Tocopherol
Mixed tocopherols are a blend of natural vitamin E compounds (alpha, beta, gamma and delta tocopherols) used in pet foods primarily as a natural antioxidant and preservative to protect fats and fat‑soluble nutrients and extend shelf life. They also supply dietary vitamin E—an essential antioxidant for immune function, skin and coat health and cellular integrity in dogs and cats—and are generally safe at typical use levels, though they are not a substitute for a complete vitamin formulation and may be less effective in animals with fat‑absorption disorders.
