Looking for the latest Diamond Dog Food Reviews? You are in the right page, read on!
The Diamond name actually encompasses three separate brands of pet food, though all of them are marketed as high-quality brands available at an affordable price point for the average pet owner.
The company believes that every pet, from shelter puppy to purebred, deserves the best nutrition that money can buy.
The Diamond family of brands includes a variety of quality pet foods that meet the preferences and nutritional needs of dogs in all life stages, from all lifestyles, and of all activity levels.
Of the three brands that carry the Diamond name, one is a life stages product line, one is an all-natural product line, and the third is a grain-free product line.
Diamond Pet Foods makes every effort to formulate their recipes around wholesome ingredients like real chicken, lamb, and turkey as well as fresh fruits and vegetables.
They claim that each formula is designed in keeping with the latest animal nutrition research and carefully formulated to meet the specific nutritional needs of dogs in certain life stages.

Diamond Dog Food Review
Throughout their website, they claim that their products are of the highest quality, made with the finest ingredients available.
They even provide a list of their ingredients which includes real meats, wholesome veggies, fresh fruits, whole grains, and healthy supplements.
A quick review of several products reveals that these ingredients are actually in use, though the quality varies from one brand to another.
While the Diamond line of original recipes makes use of corn, wheat, and by-products, the Diamond Naturals line does not.
The Diamond Naturals Grain-Free is even one step higher on the quality scale. The lesson here is that some Diamond dog foods offer decent quality, you need to be careful which one you buy because some do not.
1. Chicken & Rice Formula
This dry dog food is marketed as an adult dog recipe, though it is actually complete and balanced for dogs in all life stages. As part of the Diamond Naturals product line, this formula is free from corn, wheat, and soy ingredients.
It features fresh chicken as the main ingredient with digestible whole grains and healthy fats for nutritional balance. With plenty of meat-rich protein, this recipe supplies your dog with “the energy and muscle building blocks he needs to stay active and strong”.
Supplementary proteins include egg and fish meal, while digestible whole grains like brown rice and barley supply carbohydrates. The recipe also includes fruits, vegetables, and fiber sources for key nutrients and digestion support, with healthy fats from chicken fat and salmon oil for omega fatty acids.
It contains probiotics for gut health and chelated minerals for better nutrient absorption. Though grain-inclusive, this balanced formula is free from corn, wheat, and soy, making it a nutritious choice for most dogs, unless they have specific grain sensitivities.
2. Beef Meal & Rice Formula
Marketed for adult dogs, this meal offers enough nutrients to fully support a grown dog’s daily requirements for overall good health. The mixture is made up of real animal proteins, superfoods such as kale and blackberries, and antioxidants.
This particular recipe is made with beef meal as the first ingredient. Contrary to what most believe, beef meal can be excellent for dogs, particularly if it’s made by a good-quality brand. It’s a highly-concentrated source of natural protein that is also used to improve the amino acid profile of a formulation.
While fresh beef meat contains a lot of moisture and little protein, beef meal removes most of the water for a denser source of protein by volume.
The second ingredient is sorghum, a cereal grain that provides a lot of benefits to our furry companions. It’s a digestible grain that is high in antioxidants and rich in zinc, B1, iron, niacin, and dietary fiber.
A few kinds of healthy grains such as barley, white rice, and rice bran follow. These provide the carbohydrates, vitamins, minerals, and a significant portion of dietary fiber that your pet needs.
A word of warning to pet owners whose dogs have food sensitivities. Grains can trigger food allergies in some dogs, so make sure your pet is not sensitive to any of these. Otherwise, grains are supremely healthy and nutritious.
Chicken fat provides the bulk of fat in this recipe. While that may not sound like an attractive ingredient in a pet food, chicken fat is a good source of Omega-6 and Vitamin E. It also enhances the aroma of the food to entice pets to eat.
Aside from the mineral and vitamin content of the Natural Beef Meal & Rice recipe, it also contains a healthy serving of probiotics — 80,000,000 CFU/lb to be exact — to keep your canine’s digestive system in tiptop shape.
We don’t see a problem with the ingredients in this list, except perhaps for the grains but that’s only problematic for sensitive dogs. The addition of live cultures into the feed is an excellent idea, because these are great at boosting the immune system and regulating the intestinal flora.
3. Lamb Meal & Rice Formula
This recipe for adult dogs is mostly the same as the beef meal and rice formulation, with the exception of lamb being the main star of the meal.
It starts off with lamb meal as the first ingredient to ensure that dogs get as much protein as they need. (Lamb meal is the protein-dense counterpart of fresh lamb because all of its moisture has been mostly removed.)
Lamb is considered by many to be a great alternative to beef taste-wise, and it offers another option for sensitive dogs who can’t tolerate beef. And since lamb is an excellent source of not only protein but of amino acids as well, this recipe is a great addition to any flavor rotation.
After lamb comes these five grain ingredients: ground white rice, cracked pearl barley, grain sorghum, rice bran, and millet. White rice is easily digestible and offers dogs plenty of energy, barley is high in fiber and low in cholesterol, and sorghum is gluten-free yet high in antioxidants. Rice bran is a significant source of fiber, B vitamins, manganese, selenium, and magnesium, while millet is rich in phosphorus and iron.
In between the grains, there is egg product and dried yeast. The egg product is just a convenient form of an egg, which can mean whole eggs or parts of it. Meanwhile, the dried yeast is an excellent source of non-animal protein and is even being touted as a novel type of protein. There’s also chicken fat in there to add omega fatty acids into your dog’s diet.
The meal would not be complete without whole foods such as kale, pumpkin, blueberries, spinach, and more to give it a boost in terms of vitamins and minerals. This is good if your pet is not sensitive to most kinds of foods. Unfortunately, if he is, the long list of ingredients may make it hard to see exactly which will trigger his allergies.
4. Skin & Coat Formula All Life Stages
Multiple-pet households will find this All Life Stages recipe a valuable find. Because it’s designed to meet the daily requirements of pups of all ages, it’s a more convenient way to feed dogs instead of having a different dog food for each.
The Skin & Coat formula is especially formulated to give dogs with food-related allergies a complete and holistic nutrition by utilizing known hypoallergenic ingredients.
For example, the recipe starts with a novel animal protein source (novel means not commonly used) such as wild-caught salmon, which is a really good source of Omega-3 fatty acids. Omega-3 fatty acids keep a dog’s skin and coat shiny and healthy, decreases inflammation, and supports the immune system.
The second ingredient is fish meal. Fish meal is rendered food that removes most of the moisture from fresh fish, thus making it more concentrated than fresh fish which is composed of 70% water. If made by a reputable dog food brand like Diamond Pet Foods, it should still retain a lot of its amino acid, mineral, vitamin, and fat contents.
Instead of grains which can trigger food allergies in sensitive dogs, this recipe uses potatoes, lentils, peas, pea flour, and flaxseed instead. The potato is rich in Vitamins A, C, and B6, among others. It also has carbs in it to convert into energy and provide as a source of heat to the body.
Lentils are low in calories but high in iron and fiber to keep dogs feeling fuller longer (ideal also for dogs that need a bit of dieting). Peas are high in vitamins and minerals that support good vision and a strong immune system.
Pea flour is the powder from roasted peas and is heavy on iron, calcium, and fiber. Flaxseed gives off plenty of Omega-6 fatty acids that nourish the skin from within to give it a healthy feel and shine.
The fat content of the recipe comes mostly from the canola oil, which is a significant source of polyunsaturated Omega-3 fat. And because it contains phytosterols, the canola oil helps reduce the absorption of cholesterol into our doggy’s bodies.
Because this recipe is hypoallergenic, there is no egg product to be found anywhere in the list. It also does not include corn, wheat, grain, or artificial colors, preservatives, and flavors. However, it is chock full of whole food veggies and fruits and contains guaranteed probiotics to support a dog’s digestive health.
5. Large Breed Adult Chicken & Rice Formula
Large breed doggies need a large amount of nutrition to meet their daily requirements. This chicken and rice formulation is specifically designed to meet those requirements to support their overall health. This means that every meal needs an extra helping of nutrients.
Because animal protein should always be the first ingredient in a high-quality pet food, it’s no surprise that the first in the list is fresh chicken, and the next one is chicken meal. Chicken happens to be a favorite among dogs (just not the food-sensitive ones) because it has a yummy flavor that agrees with most.
Chicken is a good source of essential amino acids and glucosamine that are important for building and maintaining healthy bones and joints. It’s also known for containing Omega-6 fatty acids that are good for shiny hair and healthy skin.
Chicken meal, on the other hand, is mostly the same but more concentrated in nutrients since it’s made of rendered chicken that has had its moisture removed.
After the two main protein ingredients, the next on the list is a parade of grain foods such as whole grain brown rice, pearled barley, white rice, rice bran, and sorghum. Grains aren’t bad per se. They’re actually nutritious and quite healthy.
For example, brown rice is full of natural fiber — a necessary nutrient for digestive health. It’s also packed with riboflavin, iron, calcium, and more.
White rice is a good carbohydrate source, particularly for dogs who suffer from upset stomachs. It’s easy to digest and can help bind stools in cases of loose bowel movement.
Pearled barley is full of dietary fiber and plant protein; Rice bran is a byproduct of the removal of brown rice layers to make white rice, so it's full of the same fiber and vitamins that make brown rice so good.
Aside from these, there are also a number of fruits and veggies that provide powerful antioxidants. These include oranges, kale, pumpkin, blueberries, spinach, carrots, coconut, papaya, and more.
There are also added supplements to make it even more nutritious for large dogs as well as guaranteed levels of live microorganisms to support a canine’s digestive system.
We like how even the use of several kinds of grains in this recipe doesn’t equal a high caloric value. At only 327 kcal per cup, it’s still an average amount of calories that is lower than plenty of grain-free alternatives.

This company set out with the goal of producing high-quality, premium pet foods at an affordable price and today the brand is favored by breeders, trainers, vets, and health-conscious pet owners in over 100 different countries.
Though Diamond Pet Foods has expanded rapidly, it remains a family-owned company that follows Midwestern values. They take seriously the task of creating high-quality pet food products that they can be proud of.
Is Diamond Made in the United States?
Diamond Pet Foods is a U.S.-based company. In fact, it is one of the largest manufacturers of the pet products in the country. Though Diamond Pet Food products are available in more than 100 countries, most of their products are made right here in the United States.
Diamond Pet foods owns five manufacturing facilities across the country where they produce more than just Diamond pet food products.

Where Do They Get Their Ingredients?
The Diamond Pet Foods company is headquartered in Meta, Missouri but they have five manufacturing facilities in four states. According to the FAQs on the company website, all Diamond Pet Foods products are manufactured in the United States but the company does not state where they get their ingredients.

Diamond does state on their website that they have “developed unique relationships with their suppliers” and, as a privately held company, they can “look beyond their short-term, quarterly shareholder results and enter into long-term agreements with their vendors”.
Still, however, no mention is made of exactly where those vendors are located.
