The Costco Kirkland Signature Adult Chicken, Rice & Vegetable Formula is characterized by an estimated dry matter protein content of 28.9%, a fat content of 17.8%, and carbohydrates at approximately 45.3%. Across the entire Kirkland Signature product line, the average protein content is around 28%, with an average fat level of 15%.

The primary ingredients in the Costco Kirkland Signature Adult Chicken, Rice & Vegetable Formula include chicken, chicken meal, whole grain brown rice, cracked pearled barley, and chicken fat. Chicken and chicken meal are excellent sources of protein, essential amino acids, and contribute to the overall meat content of the food. Brown rice and barley provide digestible carbohydrates and fiber, contributing to energy and digestive health. Chicken fat is a valuable source of omega-6 fatty acids, crucial for skin and coat health.
Other notable ingredients include egg product, which is easily digestible and rich in biological value, and beet pulp, a fiber source that can benefit intestinal health. The inclusion of fish meal adds another source of protein and essential fatty acids. Flaxseed is a notable plant-based source of omega-3 fatty acids, and dried yeast can offer nutritional benefits, although it’s a point of consideration for dogs with specific sensitivities. Peas contribute quality carbohydrates and fiber, while chicory root acts as a prebiotic to support digestive health. The presence of chelated minerals indicates enhanced nutrient absorption, a characteristic often found in higher-quality dog foods. However, the use of sodium selenite, a form of selenium, is noted as a point of consideration compared to more natural sources.
