This formula lists real pasture-raised beef as its primary ingredient, a crucial component for muscle development. While specific protein percentages can vary slightly batch-to-batch, adult dog food typically ranges from 20-30% crude protein. This protein provides key amino acids necessary for muscle protein synthesis and repair, supporting lean muscle mass. The 'pasture-raised' designation suggests cattle were allowed to graze, often implying a diet more aligned with natural foraging and potentially a better fatty acid profile in the meat itself, contributing to overall canine health and solid muscle structure. This foundational ingredient supports a dog's active lifestyle.

The K9 Strain PROPRIETARY PROBIOTICS are formulated to support digestive and immune health. While the exact Colony Forming Units (CFUs) per serving are often proprietary information for specialized blends, leading formulations typically contain billions of CFUs to ensure efficacy in establishing a healthy gut microbiome. These beneficial bacteria, along with prebiotics, aid nutrient absorption and waste processing. Antioxidants further bolster the immune system by combating oxidative stress. The brand guarantees these are 'live and active cultures' through the manufacturing process, promoting a healthy digestive tract and overall wellness for adult dogs.

The inclusion of superfoods like blueberries and oranges goes beyond standard vitamin fortification, offering synergistic benefits. Blueberries are rich in anthocyanins, potent antioxidants that help neutralize free radicals, potentially reducing cellular damage and supporting cognitive function. Oranges provide Vitamin C, an key antioxidant for immune support, and flavonoids, which can contribute to anti-inflammatory processes. Together with omega fatty acids for skin and coat health, these ingredients create a thorough nutrient profile, aiming for enhanced cellular health and immune response in adult dogs.
