Review of Guaranteed Analysis

Crude Protein (min) of 12.50%: The primary contributors to the crude protein content in this pet food are likely to be the dried egg product, brewers rice, and whole grain corn. Dried egg product is a high-quality protein source that provides essential amino acids. Brewers rice, although a carbohydrate source, also contains some protein. Whole grain corn contributes protein as well, but it is not as high quality as animal-based proteins. The sodium caseinate, a form of casein protein found in milk, also adds to the overall protein content.

Fish oil is another contributor, providing essential fatty acids like omega-3s which are beneficial for a dog's coat and skin health.
