Diamond Naturals Dog Food Flavors and Lines

Diamond Naturals has five dog food lines, each with different target canines and different price points.

Diamond Naturals Diamond Dry Food

Diamond by Diamond Naturals is the brand’s budget-friendly line of foods. These recipes include less than desirable meats like chicken by-product meal and fillers such as corn. But they also provide a higher than average amount of protein and fat, which gives you more bang for your buck.

Available Flavors & Types:

  • High-Energy
  • Maintenance
  • Original
  • Performance
  • Premium Adult
  • Puppy

Diamond Naturals Dry Food

The premier line called, simply, “Diamond Naturals” uses higher quality ingredients and reduced fillers compared to the Diamond line. Most have a closer to average amount of fat and protein but the higher quality ingredients mean the sources of these macronutrients are more digestible. This line costs more than the Diamond line but is still relatively affordable as far as natural dog foods go.

Available Flavors & Types:

  • Renal Formula

Diamond Naturals Pro89 Dry Food

This line consists of a single product made with 89% animal-derived ingredients. It has 30% protein and 20% fat to provide vital energy to dog athletes and working canines. Given the quality of the ingredients and the macronutrient profile, it is priced reasonably well.

Available Flavors & Types:

Diamond Naturals Grain-Free Dry Food

The grain-free line is made for owners who want to feed their dogs a more traditional diet and for dogs with sensitivities to grains. These are all meat-first recipes but do get a lot of their protein from legumes. They have average protein and fat levels and are priced about even with most mid-range grain-free brands out there.

Diamond Naturals Dog Food Ingredient Analysis

To perform our ingredient analysis, we chose one of this brand’s most popular choices, the adult beef meal & rice formula from the Diamond Naturals premier line.

No products found.

Ingredient List:

  1. Beef meal
  2. Grain sorghum
  3. Ground white rice
  4. Dried yeast
  5. Egg product
  6. Rice bran
  7. Cracked pearled barley
  8. Chicken fat
  9. Dried beet pulp
  10. Natural flavor

This recipe starts with a named animal protein, which is good. But that protein is a meal, which calls into question the quality of the meat used. Beef meal, in particular, can consist of a large amount of ground bone which has relatively little protein. Additionally, meal meat is rendered not fresh, and many animals, including those sick and dying, can be used for rendering.

As far as grains go, sorghum is a relatively good one to include in dog food. It does not spike blood glucose levels as fast as corn and is more digestible than many whole-form grains.

White rice, especially in the ground form, is another highly digestible grain. However, it does not contain a lot of nutrients and mainly provides calories in the form of carbohydrates which dogs do not utilize as well as fat and protein.

Yeast offers a lot of micronutrients that are readily digestible to canines. These single-celled organisms are also highly palatable to dogs and this ingredient is often added as a flavor enhancer.

Egg contains a ton of protein and fat, which is great for dogs. Egg “product” is less desirable than “chicken eggs” or more specific egg ingredients. This recipe likely includes eggs that failed to hatch as well as typical unfertilized eggs.

Overall, the ingredients in this food do follow the company’s claims that they use natural ingredients in this line of food. However, the quality of the individual ingredients is not as high as it could be. Additionally, the first fat listed appears farther down the list than we like to see.

Protein Content of Diamond Naturals

The first ingredient in this recipe is a named animal ingredient, which is always a good sign. The top ingredients also include eggs, another high-protein food that is great for dogs.

The total protein content of this beef recipe is 25%, which is about average for a mid-quality all life stages food. This amount is perfect for your average adult dog.

Fat Content of Diamond Naturals

Dogs rely on fat for most of their energy needs. We prefer to see the first whole-fat ingredient listed within the first five ingredients as this shows the food has enough high-quality animal fats to support normal metabolic function.

While the first whole fat in this formula shows up at number eight, the listed fat content, 15%, is about average for adult maintenance recipes. This food would work well for less active dogs and older canines, but may not have enough quality fats to support active pups.

Pros of Diamond Naturals Dog Food

With this brand, you have a lot to choose from. Between their lowest-priced Diamond line and their premier-priced Care line, you are sure to find something that will work for your dog.

Here are some additional beneficial takeaways from this brand:

  • Meat-first ingredients
  • Most lines do not use fillers
  • A range of prices to fit every need
  • Puppy, adult, senior, and all-life stages options available
  • Allergy-friendly options
  • Company-owned packing plants
  • All products produced in the USA

Cons of Diamond Naturals Dog Food

Overall, this is a quality brand with a lot to offer. However, some of their products include less than desirable ingredients and, with the exception of their Pro89 line, most recipes do not include as many animal ingredients as we would hope to see.

Here are some additional negative takeaways from this brand:

  • Some recipes include animal by-product meal
  • Some recipes use fillers like corn
  • Ingredients are globally sourced
  • Recipes use synthetic nutrients
  • Some recipes include a high amount of legumes
  • Some products are priced too high for the ingredient quality

Diamond Naturals Dog Food Price Tag

All of this brand’s products sit between the lower mid-range and upper price points for dog food.

Their Diamond line is on par with most pricier grocery store brands and is fairly affordable considering what you get. The premier DN line has a mid-range price tag which fits well with what is in the bag. However, their grain-free line, which has less protein and fat, is priced much too high in our opinion.

The Care line is the highest priced line from the company. This is typical of prescription-style diets and may be worth paying if your dog truly needs one of these specific formulas. If not, you are better off saving money with another option that is likely to contain more species-appropriate ingredients.

Diamond Naturals Dog Food Recall History

The company has had three major recalls since 2009, all stemming from the same incident.

On April 6th, 2012, the company recalled the premier line adult lamb and rice formula due to possible salmonella contamination. That recall was expanded to include the puppy and small breed lamb and rice formulas over the following two months.

Salmonella is not generally dangerous to dogs but can cause illness in humans who handle contaminated food. The company has had no other major incidents since.

Which Dogs Can Benefit from Diamond Naturals?

Due to the vast selection of different formulas available from this company, there is sure to be something for just about every dog out there. Athletes and working dogs would benefit from the high-protein, high-fat Pro89 food, while the average pet would do great on the basic or premier lines.

Which Dogs Should NOT Be Fed Diamond Naturals?

Dogs that are prone to canine dilated cardiomyopathy should not eat the grain-free line from this brand since much of the protein comes from legumes, which can cause issues in these sensitive canines. Dogs with kidney or protein metabolism problems should stick to the Care or premier lines since they contain less protein than the other options.

The Final Word for Diamond Naturals Dog Food

Overall, Diamond Naturals does live up to its reputation. Most of the company’s recipes are made with quality ingredients that include plenty of animal protein. And the wide selection of recipes and focused formulas makes it easier to find the right food for your dog, no matter your budget.
