Diamond Premium Dry Dog Food
Verified Jun 15, 2026
This is a dry kibble formulated for active dogs of all ages, including large-breed puppies, with 26% protein and 18% fat to support higher energy needs. Chicken by-product meal is the main animal protein, complemented by corn, wheat, and beet pulp for carbohydrates and fiber, plus added fish meal, salmon oil, and flaxseed for omega fatty acids. It also includes glucosamine for joint support and a blend of probiotics aimed at digestive and immune health.
Overall this is a solid, higher-energy all‑life‑stages formula that is appropriate even for large-breed puppies, which is an important safety point for growing large dogs. It uses chicken by-product meal as the primary protein source, with grains like corn and wheat supplying additional protein and calories. The added omega fatty acids, glucosamine, and probiotics are nice extras for active or athletic dogs, as long as they tolerate chicken and grains well.

At a Glance
KibbleLab Review
Strengths
- AAFCO complete and balanced for all life stages, including large-breed growth, so it can safely be used for puppies and large-breed puppies as well as adults.
- Good protein and fat levels (26% protein, 18% fat) that suit many active or working dogs who need more calories and amino acids.
- Chicken by-product meal, egg product, fish meal, and salmon oil provide multiple animal protein and omega-3 sources, supporting a more complete amino acid and fatty acid profile.
- Includes added glucosamine and a blend of probiotics (80 million CFU per pound) which may support joint comfort and digestive health in active dogs.
Considerations
- Contains chicken by-product meal and egg, so it is not a good choice for dogs with known chicken or egg allergies.
- Corn and wheat are significant components; while very nutritious for most dogs, they won’t suit households specifically seeking grain-free diets for personal preference reasons.
- The relatively high fat and calorie density (about 435 kcal per cup) may be too rich for dogs with a tendency to gain weight easily or those with lower activity levels; their portions may need careful control.

Top 5 Ingredients Explained
01
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.
02
Whole Grain Corn
Whole grain corn is commonly used as a carbohydrate and energy source in pet foods, providing digestible starch, dietary fiber, some protein, and B vitamins and minerals while retaining more nutrients than refined corn. It is generally economical and well-tolerated by most dogs and many cats, but because cats are obligate carnivores animal-based proteins are nutritionally more important, and pets with grain sensitivities, certain metabolic conditions, or requirements for low-carbohydrate diets may need alternatives; proper sourcing and processing also reduce mycotoxin risk and improve digestibility.
03
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.
04
Chicken Fat
Chicken fat is used in dog and cat foods as a concentrated energy and flavor source that supplies essential fatty acids (notably linoleic acid) and aids absorption of fat‑soluble vitamins, improving palatability and supporting skin and coat health. Because it is calorie‑dense, diets must account for added fat to prevent weight gain, and quality (proper rendering and antioxidant protection to prevent rancidity) is important; although fats are less commonly allergenic than proteins, pets with poultry sensitivities may still react in some cases.
05
Mixed Tocopherol
Mixed tocopherols are a blend of natural vitamin E compounds (alpha, beta, gamma and delta tocopherols) used in pet foods primarily as a natural antioxidant and preservative to protect fats and fat‑soluble nutrients and extend shelf life. They also supply dietary vitamin E—an essential antioxidant for immune function, skin and coat health and cellular integrity in dogs and cats—and are generally safe at typical use levels, though they are not a substitute for a complete vitamin formulation and may be less effective in animals with fat‑absorption disorders.
