What experts liked
Diamond Naturals is a plant-based dry dog food using a moderate amount of named meat meals as its main sources of animal protein
- Dog Food Advisor
We like a lot of things about this food, including the meat protein percentage and many of the ingredients. The fat percentage is very high so this food would only be recommended for very active dogs or dogs who need to gain weight.
- Dog Food Guru
Quality meats, but better on the canned products and it's gluten free. Customers who feed the high quality Diamond Naturals notice that their dogs are more active and have shinier coats, better breath and a healthier demeanor.
- PetFoodTalk.com
The overall quality of the ingredients looks very good. The lamb meal is a good source of protein. In addition to the rice, there are a lot of other carbs in this food,but they come from some of the less common grains so if your dog has problems with grains, he might be able to eat this food. It has a good named source of animal fat (chicken preserved with vitamin E) and good sources of fiber.

We had no trouble tracking down this brand’s mediocre dry food, but its wet formulas aren’t available on Chewy, Amazon, PetSmart, or PetCo. Approved wet formulas: any.

The pumpkin, an unusual ingredient, but a good one. A fine source of fiber; some dog owners use it to clear up constipation.Good variety of unusual “superfoods”. All in all, this appears to be a good quality product, and certainly a worthwhile alternative to super premium brands if cost is an issue.

The Naturals line of dry foods is much higher quality, made with quality proteins and digestible carbohydrates including white rice, cracked pearled barley, and fresh fruits and vegetables. The Naturals Grain-Free product line is another step up, made with digestible gluten-free and grain-free carbohydrates like garbanzo beans and sweet potatoes.

What experts didn't like
he fifth ingredient is dried yeast, which can be a controversial item. Dried yeast contains about 45% protein and is rich in other healthy nutrients. Critics argue yeast ingredients can be linked to allergies. This may be true, but (like all allergies) only if your particular dog is allergic to the yeast itself.What’s more, a vocal minority insist yeast can increase the risk of developing the life-threatening condition known as bloat.
- Dog Food Advisor
Minus: Contains sodium selenite.
- Petsumer Report
We are somewhat concerned about the cellulose in the food – not a favorite ingredient. Some dogs may have trouble digesting it or it might cause dogs to produce lots of stool and flatulence.
- Dog Food Guru
Some of the dry formulas, though, contain less than ideal ingredients
- PetFoodTalk.com
The only potential problem I see is the flaxseed if you are a dog breeder. There is a lot of rice in the food (ground rice, rice bran), as well as a lot of other carbs but the food is labeled “lamb meal & rice” so I think this is to be expected.

Salt – More than enough salt should be contained in the ingredients to satisfy a dog’s requirements without adding extra. Salt is added to enhance flavour, but too much of it can lead to heart problems and/or high blood pressure.

The line of original recipes is the lowest quality of the three product lines, though it is marketed as a “super premium pet food without the premium price”.Their website states that these products are formulated with high-quality ingredients, yet a review of several recipes reveals the use of low-quality ingredients like wheat flour and corn gluten meal.

An Overview On Dry Dog Food

Dogs are like members of our families, so of course, we want to keep them as healthy and happy as possible. The foundation for that is proper nutrition. A consistent, high-quality diet is the key to keeping your dog looking and feeling great. Feeding your dog the best dog food will keep them functioning at their best and can ward off chronic diseases, leading to a longer life. Dry dog food is very common and convenient, as it does not require refrigeration.

There’s a ton of different types of dry dog food out there, so the choices can be overwhelming.  You should look for dog food that is labeled as “complete and balanced,” which means the food contains the minimum amount of all the nutrients necessary for dogs. This standard is regulated by the Association of American Feed Control Officials. Keep in mind that buzzwords like “premium” and “immune supporting” are not regulated and should not carry much weight in your choice.

Just as with human food, you want to make sure your dog is eating a diet with real, whole foods and one that is free from artificial preservatives and additives. Make sure your dog’s food contains a high-quality animal protein source, like lamb, chicken or turkey. Leading brands, such as Orijen Tundra, contain multiple protein sources, including chicken, turkey, flounder and egg.

Many veterinarians recommend avoiding dog food that contains grains like corn, wheat and soy, as dogs do not need these starches. Although many healthy dog foods contain carbohydrates in the form of fruit and vegetables, brands like Taste of the Wild tout their grain-free recipe.

Other healthy ingredients include probiotics, which benefit the intestinal and immune systems, and minerals. Minerals should be chelated or proteinated for maximum absorption.

Some dogs need special diets, and diets should be adjusted for puppies and senior dogs. The right dog food for your pet will meet all of their needs and come at an affordable price.

DYWM Fun Fact

Dogs have been humans’ companions for more than 30,000 years. In the beginning, man’s best friend’s diet did not get the consideration it does today. Dogs generally ate the scraps that were left over from their humans. Around 1860, businessman James Spratt introduced the first commercially prepared dog food. Official nutritional requirements for dogs and cats were established in the mid-1980s. Dry dog food, or “kibble” as we know it today, became popular in the 1950s.

As of 2017, commercial pet food was a $26 billion industry. These days, a lot of pet parents are turning to online retailers like Amazon and Chewy to get their dog food delivered straight to their door.

The Dry Dog Food Buying Guide

  • Make sure to feed your dog the proper amount. Overfeeding your dog ups their risk of obesity and associated health problems. There are some formulas to determine how much you should be feeding your dog depending on their size and breed, and your veterinarian can also provide you with guidance.
  • Puppies need small, frequent meals, while adult dogs can eat just one to two meals per day. Some dogs are grazers, meaning that they will eat small amounts throughout the day, but many more will eat all the food that is given to them at a time, which is why it’s important not to overfeed them.
  • Price is an important factor in dog food, as it’s one of the major ongoing expenses associated with being a pet owner. A higher price tag does not necessarily translate to a superior product. A moderately priced brand such as Nature’s Recipe scores high marks for its quality.
  • To keep your dog’s food fresh, make sure it is sealed. Some brands come with resealable tops, or you can put it in an airtight container, preferably made of glass or stainless steel. Make sure you keep your dog food in a cool, dry place. Moisture and heat can compromise the food’s safety and quality.
  • Just like human food, dog food has an expiration date. Dry dog food is generally good for one year. Never give your dog food that smells or looks spoiled.
  • It’s important that the food you choose is a good fit for your dog. If your dog rejects a food or it makes them sick, it may not be the optimal choice for them. Consult with your veterinarian to find the type of food that’s best for your pet.
  • Make sure you wash the bowls your dog eats and drinks from regularly, ideally every day. Once a week, they should be sanitized with a bleach solution. Stainless steel bowls are the easiest to keep clean.
