Recipe and Label Analysis
To provide a comprehensive analysis, Nature’s Domain Turkey and Sweet Potato was chosen to represent the entire line. This formula is estimated to have a dry matter nutrient content of approximately 26.7% protein, 15.6% fat, and 49.7% carbohydrates.
The primary ingredients in this formula are turkey and turkey meal. Turkey is a lean protein source rich in essential amino acids. Turkey meal is a concentrated form of turkey, providing nearly 300% more protein than fresh turkey, making it a valuable ingredient for muscle development and overall health.
Following the protein sources, we find sweet potatoes and potatoes, which are gluten-free sources of complex carbohydrates, dietary fiber, and beta carotene. Peas are also included, offering another source of carbohydrates and natural fiber. However, it’s important to note that peas contain approximately 25% protein, which is factored into the overall meat content assessment.
Canola oil is used as a source of omega-3 fatty acids. While canola oil can be a source of these essential fats, plant-based oils are generally less bioavailable to dogs compared to fish oil. Dried yeast is present, which some believe offers benefits like flea repellency and immune support, while others link it to allergies. Unless your dog has a specific yeast allergy, it’s generally considered a nutritious addition.
Flaxseed is another good plant-based source of omega-3 fatty acids and fiber, though its protein content is also considered in the overall analysis. Salmon oil is a significant ingredient, providing readily bioavailable EPA and DHA omega-3 fatty acids, which are crucial for cognitive function and overall health.
Other beneficial ingredients include chicory root, a source of inulin and a prebiotic that promotes healthy gut bacteria, and dried fermentation products, which act as probiotics to aid digestion. The inclusion of chelated minerals is also a positive, as these minerals are more easily absorbed by the body. However, the presence of sodium selenite, a controversial form of selenium, is noted as a potential drawback compared to more natural selenium sources like selenium yeast.
