Native Pet Probiotics for dogs was formulated by a team of veterinary nutritionists, specializing in gut health and the canine microbiome. Through deep research and analysis, we selected the specific probiotic strains that work together to improve long-term health. The all-natural prebiotics support the probiotic community, as they work to improve the immune system and digestion. Lastly, we added grass-fed bone broth for flavor, as all dogs love the taste of savory bone broth!
