Salmon used in our formulas is non-farmed, wild-caught Sockeye from the Pacific Northwest. Salmon is low in saturated fat, a source of high-quality protein, and contains other essential nutrients such as vitamin D, zinc, and selenium. The Omega 3 fats found in salmon have contributed to a healthier immune system and reduced the risk of specific cancers and age-related macular degeneration in the eyes. Healthy Paws Canine Complete Salmon Dinner contains Healthy Paws™ K9-5 Species-Specific Probiotic Blend, Atlantic Sea kelp and an omega-3 blend of herring and sardine. Healthy Paws proprietary species-specific probiotic blend is derived from both healthy domestic dogs and free-range wolves. This 5-strain probiotic blend contains and exhibits prebiotics, antioxidant, anti-inflammatory properties, and proprietary ingredients, which serve as fuel to sustain the multiplication and growth of healthy probiotic organisms within the body.
