Health & happiness start in the gut – our specialty. At family-owned NutriSource, we believe the secret to health is successful digestion and absorption of balanced nutrition. That’s why we focus on supporting the gut microbiome with our proprietary blend of prebiotics, probiotics, trace minerals and selenium yeast. We call our gut-focused proprietary blend Good4Life because these ingredients nourish the gut microbiome, building the ultimate foundation for a long and happy life. Scientifically formulated, chicken free, Large Breed NutriSource Beef & Rice includes a blend of beef, rice, carefully selected ingredients, and Good4Life to provide essential nutrients for optimum health and long life. Feed with confidence knowing that you’re part of a family that loves your pets just as much as you do. Health begins here.

NutriSource diets are packed with probiotics for superior microbial digestion. These probiotics, coated on the outside of the kibble, absorb quickly and therefore colonize faster to aid in digestion.
Our diets also use a powerful prebiotic called BIO-MOS that supports the intestinal tract in removing harmful pathogenic bacteria while feeding gut flora for optimal digestion.
NutriSource products feature Bioplex trace minerals and Omega 3 & 6 fatty acids to provide fundamental nutrients to support brain function, heart health, and healthy skin and coat.
NutriSource diets contain a powerful antioxidant combination of Sel-Plex (a proprietary form of selenium yeast), DHA (Omega 3 fatty acid), and select fruits and vegetables to support proper oxidation at the cellular level.
DL Methionine, Choline Chloride, Taurine, and Carniking L-carnitine are key amino acids supplemented in NutriSource diets to nourish the heart as well as the pet’s whole body.

NutriSource® Large Breed Beef & Rice Recipe Dog Food is formulated to meet the nutritional levels established by the Association of American Feed Control Officials (AAFCO) Dog Food Nutrient Profiles for all life stages including growth of large size dogs (70 lbs. or more as an adult).
