Nutra Nuggets is one of the many brands owned by Diamond Pet Foods, a major player in the pet food industry, producing for numerous brands worldwide like Taste of the wild. While conducting this review, we encountered challenges in obtaining certain key information and specific nutrient levels, making it difficult to fully assess the quality of these kibbles.
✅ Pros
- Good Protein Sources:Animal proteins like beef and lamb, offering solid nutritional value.
- Grain-Free Options: Some recipes are grain-free with added taurine, addressing concerns over cardiomyopathy.
❌ Cons
- Lack of Transparency: Missing key nutritional information like ash calcium and phosphorus levels.
- Use of Lower-Quality Ingredients: like wheat, corn (except the grain free recipe).
- High Carbohydrate Content: From 36% to 52%
- Unknown Cooking Method: Crucial for evaluating nutrient retention. and to consider the impact of cooking on the formation of Advanced Glycation End Products (AGEs).
- Likely High in Plant-Based Proteins: Plant-based proteins are less digestible and may not provide the same nutritional benefits as animal proteins.

Puppies require higher levels of fats, proteins, and specific minerals like calcium for optimal growth. These nutritional needs are well-addressed in this formula. We regret the high carbohydrate content, especially considering the significant glycemic load it introduces. We also note the inclusion of corn and wheat is not ideal for dogs, as these ingredients are less digestible and can contribute to food sensitivities or allergies in some dogs.

This recipe offers alternatives to corn, such as peas, though wheat is still present. It is lower in protein and consequently higher in carbohydrates. However, lamb serves as a good alternative protein source, especially for dogs with allergies to chicken or beef. It’s important to note that white rice and wheat flour have very high glycemic loads. Frequent glycemic spikes can lead to insulin resistance, weight gain, and increased risk of diabetes in dogs.
Nutra-Nuggets US Performance Dog

This recipe offers no significant innovations, aside from a slight increase in fat and a minimal rise in protein. However, the protein levels may be insufficient to support and promote muscle growth. The carbohydrate content remains high, providing energy for active dogs, but the glycemic load of the ingredients is still a concern.

This is likely the most promising recipe from the brand, with improved nutrient levels to support energy needs and help maintain muscle mass and fat reserves of working dogs. However, the Sheriff Score remains modest due to the lack of essential information, such as calcium, phosphorus, and ash content—key factors in assessing the quality of animal proteins used.

A solid source of protein with “pasture-raised beef,” but this recipe is the lowest in essential macronutrients among the brand’s offerings. It shares the same shortcomings as previous recipes, such as low nutrient density and the presence of high-glycemic carbohydrates.
Our Opinion
Nutra Nuggets provides a range of formulas catering to different life stages and energy needs. However, the reliance on plant based protein, high carbohydrate content, and the presence of controversial ingredients like corn and wheat flour diminish the overall quality. The Sheriff Score reflects these concerns (And the inability to accurately assess protein quality due to the lack of nutritional information). While some formulas may meet basic nutritional needs, they may fall short of providing the right amount of proteins some dogs need, except for the US performance Professional Dog which is more interesting.
Please note that the Sheriff Score could potentially be higher if more nutritional information and details about the processing methods were available.
