Nutritional Perspective

KibbleLab Review

Strengths

  • Turkey and turkey meal provide identifiable animal protein sources at the top of the ingredient list.
  • Ancient grains like sorghum, barley, brown rice, quinoa, and chia offer complex carbs and fiber.
  • Added omega-3 and omega-6 fatty acids support skin, coat, and overall health needs.
  • Formulated to meet AAFCO standards for all life stages, including large-breed growth, which is a higher bar.

Considerations

  • Contains egg, which can be an issue for dogs with egg allergies.
  • Includes multiple protein sources, so it is not ideal as a true elimination or limited-ingredient diet for food trials.
  • Calorie density is on the higher side, so portion control is important for dogs prone to weight gain.

Top 5 Ingredients Explained

01
Turkey
Turkey is commonly used as a primary animal protein in dog and cat foods, offering highly digestible, high‑quality protein and supplying essential amino acids along with B vitamins, phosphorus and zinc to support muscle maintenance and metabolism. Its fat level varies by cut so products can be lean or richer; some pets may develop allergies to poultry, cooked bones are hazardous, raw meat carries bacterial risk, and owners should rely on balanced commercial formulations (and ensure adequate taurine for cats) if turkey is a main ingredient.

03
Grain Sorghum
Grain sorghum is a gluten-free cereal grain used in pet foods primarily as a carbohydrate and fiber source that also contributes modest plant protein, B vitamins, and minerals, often serving as an alternative to corn or wheat. It supplies energy and dietary fiber for dogs and cats but is relatively low in certain essential amino acids (like lysine), and some tannin-containing varieties can reduce palatability and nutrient digestibility—processing and balanced formulation mitigate these issues, and sourcing should guard against mycotoxin contamination.
04
Barley
Barley is a cereal grain used in pet foods primarily as a digestible carbohydrate and source of dietary fiber (including soluble beta‑glucans), along with modest amounts of B vitamins and minerals. It can support healthy digestion, help moderate post‑meal blood sugar and aid weight management in dogs, but provides limited protein for obligate carnivores like cats, must be cooked/processed for good digestibility, and may be unsuitable for pets with grain sensitivities or calorie‑restricted diets.
View ingredient
05
Brown Rice
Brown rice is a whole-grain carbohydrate and fiber ingredient commonly used in dog and cat foods to provide digestible energy, dietary fiber, and modest amounts of B‑vitamins and minerals; it typically offers more nutrients and fiber than white rice. It’s generally well tolerated and can help with sensitive stomachs, but because it is high in carbohydrates (not a primary protein source) and can contain trace inorganic arsenic depending on sourcing, it should be included in balanced formulations and monitored in overweight or diabetic pets.
