Diamond Original Dry Dog Food
Verified Jun 17, 2026
This is a dry kibble designed for moderately active adult dogs and off-season sporting dogs, providing 24% protein and 12% fat. It uses meat meal and chicken by-product meal as the primary animal protein sources, along with corn and wheat for carbohydrates, and includes added omega fatty acids for skin and coat support. The formula also supplies guaranteed probiotics to help support digestive and immune function and is complete and balanced for adult maintenance according to AAFCO.
This adult maintenance kibble offers a straightforward, moderate-protein formula built on grains with animal meals and by-products for protein. It’s a practical option for healthy adult dogs who do well on corn- and wheat-based diets and don’t need a highly specialized food. The added probiotics and omega-3 and -6 fats are nice extras for gut and skin support, especially at this price-point category of formulation.

At a Glance
KibbleLab Review
Strengths
- Provides 24% protein and 12% fat, which is appropriate for many average adult dogs at maintenance.
- Uses animal-sourced meals and chicken by-product meal, which can be nutrient-dense protein sources when well made.
- Includes several probiotic strains that may help support a healthy digestive tract.
- Contains added omega-3 and omega-6 fatty acids, which can support skin and coat health.
Considerations
- Chicken by-product meal and meat meal could be an issue for dogs with chicken or mixed-meat allergies.
- Corn and wheat are fine ingredients but may not suit dogs that do poorly on these particular grains.
- Formulated for adult maintenance only, so it is not appropriate for puppies or pregnant or nursing dogs.
- Protein level is moderate rather than high, so very active or working dogs may need a higher-protein formula.

Top 5 Ingredients Explained
01
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.
02
Meat
Meat is a primary animal-based source of protein and fat in pet foods, providing essential amino acids, highly bioavailable vitamins and minerals (including B vitamins, iron and zinc) and nutrients such as taurine that are particularly important for cats. While meat supports muscle maintenance, growth and palatability, it must be included within a balanced, complete formulation or appropriately supplemented because plain muscle meat can be deficient in calcium and other nutrients, and considerations about quality, fat content, sourcing, species-specific sensitivities or allergies, and pathogen risk with raw feeding are important.
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 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.
05
Yeast
Yeast (such as brewer’s, nutritional yeast, or yeast extracts) is used in pet foods as a palatability enhancer, a supplemental protein and B‑vitamin source, and for functional components like beta‑glucans and mannans that can support immune and gut health. It can help with appetite, skin/coat quality and digestion, but some pets may be allergic, product strains and processing vary in quality, and higher purine or added-salt levels in certain yeast products can be a concern for animals with specific medical or dietary restrictions.
