It is clinically proven that meat proteins provide a superior amino acid profile than plant-based proteins. Amino Acids are the building blocks of the body’s cells. That is why 4 Strong Paw’s first ingredient is chicken meal with the addition of salmon meal to allow for a high inclusion of meats, plus nourishing chicken liver and whole egg; excluding grains and plant proteins that are non-beneficial to your pet’s nutritional requirements. Our multiple meat blends provide highly digestible, quality proteins for excellent bioavailability (good digestibility). The ancestral-based meat diet builds strong muscles, bones, teeth, heart and eyes.
