Choosing the right dog food is a crucial decision for any pet owner aiming to ensure their canine companion thrives. With a plethora of options available, navigating the market can be overwhelming. This review delves into Diamond Naturals Grain-Free dry dog food, a product line that has garnered attention for its specific formulations. As the creator of Dog Food Advisor, my personal experience with the tragic loss of my dog Penny due to commercial dog food has fueled a deep commitment to providing transparent and thorough reviews. This analysis aims to equip you with the knowledge to make an informed decision for your dog’s health and well-being.
Diamond Naturals Grain-Free product range consists of three distinct recipes, each earning a commendable 4 out of 5 stars from Dog Food Advisor. This rating reflects a careful evaluation of ingredients, nutritional content, and overall quality. The brand’s commitment to providing options for dogs with specific dietary needs, such as those requiring a grain-free diet, is evident in this line. For owners seeking to understand the nutritional breakdown and potential benefits of these formulas, an in-depth look at their composition is essential.
Recipe and Label Analysis
To provide a comprehensive overview, we will analyze the “Diamond Naturals Grain-Free Pasture-Raised Beef and Sweet Potato” recipe as representative of the entire grain-free line. This approach allows for a detailed examination of the primary ingredients and their nutritional contributions.
Estimated Dry Matter Nutrient Content:
- Protein: 26.7%
- Fat: 15.6%
- Carbohydrates: 49.7%
The primary protein source in this formula is beef, followed by lamb meal, which is a concentrated source of protein. Sweet potatoes provide a gluten-free source of complex carbohydrates and are rich in fiber and beta carotene.
However, the recipe also includes a significant amount of legumes: peas, lentils, and pea flour. While these are plant-based ingredients, their presence, especially when combined, raises the consideration of “ingredient splitting,” a practice where multiple forms of an ingredient are listed separately to position them lower on the ingredient list. Legumes also contribute to the overall protein content, which needs to be factored in when assessing the actual meat content.
Canola oil is used as a fat source. While it can provide omega-3 fatty acids, its origin (potentially genetically modified rapeseed) and lower bioavailability compared to fish oil are points to consider. Tomato pomace, a by-product of tomato processing, is included and provides fiber, though its overall impact on the food’s quality is likely minimal.
Fish meal is another protein-rich ingredient, but its anonymity is a drawback, as different fish species have varying fat profiles.
Other notable ingredients include:
- Flaxseed: A good source of omega-3 fatty acids and fiber, though it also contributes to protein content.
- Salmon oil: A highly bioavailable source of EPA and DHA, beneficial omega-3 fatty acids.
- Chicory root: Contains inulin, a prebiotic that supports healthy gut bacteria.
- Taurine: An important amino acid for heart health, particularly beneficial for dogs on grain-free diets.
- Chelated minerals: Minerals chemically bonded to protein for better absorption, typically found in higher-quality foods.
- Sodium selenite: A controversial form of selenium, considered less nutritionally valuable than selenium yeast.
Nutrient Analysis
Based on its ingredient profile, Diamond Naturals Grain-Free Pasture-Raised Beef and Sweet Potato appears to be an above-average dry dog food. The protein content on a dry matter basis is approximately 27%, with fat at 16% and carbohydrates around 50%. Compared to the average dry dog food, this line offers above-average protein and near-average fat and carbohydrate levels. Even considering the protein contribution from legumes and flaxseed, the overall composition suggests a moderate meat content in the kibble.

Our Rating of Diamond Naturals Grain Free Dog Food
Diamond Naturals Grain-Free dry dog food earns a solid 4 out of 5 stars. The line utilizes a moderate amount of named meat meals as its primary animal protein source.
