Diamond Performance Formula Dry Dog Food
Verified Jun 17, 2026
This is a high-calorie, high-protein dry food designed for very active dogs and for growth, pregnancy, and lactation. It uses chicken, chicken by-product meal, egg, and fish meal as its main animal protein sources, with added salmon oil and flaxseed for omega fatty acids and guaranteed probiotics for digestive support. The elevated fat and calorie content make it better suited to working dogs or those with high energy needs rather than the average pet dog.
Nutritionally, this is a robust, energy-dense formula that fits well for working, sporting, or otherwise highly active dogs, and it is formulated to support all life stages including large-breed growth. The 30% protein and 20% fat, mostly from animal sources, provide plenty of calories and amino acids, while added DHA, glucosamine, and probiotics are nice extras. It’s not ideal for dogs who are prone to weight gain or who need lower-fat diets, and it does contain several common protein allergens (chicken, egg, fish) that won’t suit dogs with those sensitivities.

At a Glance
KibbleLab Review
Strengths
- High protein (30%) and high fat (20%) with 83% of protein from animal sources, appropriate for very active dogs and demanding life stages like growth and lactation.
- Formulated to meet AAFCO nutrient profiles for all life stages including large-breed puppies, with appropriate calcium and phosphorus levels listed.
- Includes glucosamine, omega-3 and omega-6 fatty acids, and added DHA, which can support joint health, skin/coat, and developing puppies’ brains and eyes.
- Contains multiple probiotic strains and beet pulp, which can help support a healthy digestive microbiome.
Considerations
- Calorie density is high at 439 kcal per cup, so average-pet or low-activity dogs may gain weight easily if portions are not carefully controlled.
- Primary proteins are chicken, chicken by-product meal, egg, and fish meal, which are common allergens and not appropriate for dogs with known sensitivities to these ingredients.
- Fat level (20%) may be too rich for some dogs with a history of pancreatitis or those who require a lower-fat diet.
- Contains wheat flour and sorghum, which are fine carbohydrate sources but may not suit owners specifically seeking a grain-free formula.

Top 5 Ingredients Explained
01
Chicken
Chicken is a common animal-based protein in dog and cat foods, supplying essential amino acids, B vitamins, and energy-dense fats that support muscle maintenance, growth, and overall health; for cats it also contributes toward dietary taurine but must be present in sufficient amounts or provided via supplementation. It is prized for its digestibility and palatability, though some pets develop sensitivities or allergies to chicken, and nutritional value and safety depend on ingredient quality and processing—raw chicken carries pathogen risks and whole bones can pose choking or GI hazards.
02
Chicken By-Product
Chicken by-product is a common protein ingredient in pet foods made from edible parts of the bird not typically consumed by people—such as organs (liver, heart), necks and other tissues—and is used to add protein, flavor and nutrient density. It can provide concentrated protein, essential amino acids, B vitamins and minerals (and may contribute taurine when organ meats are included), but composition and quality vary by source, so pet parents concerned about sourcing, higher ash/fat content or chicken allergies should check the manufacturer’s labeling and quality standards.
03
Grain Sorghum
Grain sorghum is a gluten-free cereal grain used in pet foods primarily as a carbohydrate and fiber source that also contributes modest plant protein, B vitamins, and minerals, often serving as an alternative to corn or wheat. It supplies energy and dietary fiber for dogs and cats but is relatively low in certain essential amino acids (like lysine), and some tannin-containing varieties can reduce palatability and nutrient digestibility—processing and balanced formulation mitigate these issues, and sourcing should guard against mycotoxin contamination.
04
Wheat Flour
Wheat flour is commonly used in pet foods as a carbohydrate source, binder and extender that provides digestible energy, some protein (including gluten), and small amounts of fiber and B‑vitamins when enriched. While generally safe and economical for many dogs, it is not a required ingredient for obligate carnivores like cats, can contribute to excess calories or a high glycemic load, and can trigger food allergies or gluten sensitivity in susceptible pets, so animals with known wheat sensitivities or weight concerns may benefit from wheat‑free formulations.
05
Egg Product
Egg product is used in pet foods as a high-quality, highly digestible animal protein and palatability enhancer, providing complete essential amino acids, fats, vitamins (such as A, D and B12), minerals and choline, and it often serves as a binder or emulsifier when included as whole, dried or concentrated egg. It supplies bioavailable nutrients for dogs and cats but can be a food allergen for some individuals, may be higher in fat depending on yolk content, and should be properly processed (pasteurized or cooked) to reduce microbial risk.
