- Our Diamond Naturals Dog Food Rating
Diamond Naturals is a good quality, made-in-America brand of dog food. The company produces several of its own brands, and also makes food for other companies in its factories. The Naturals line is a moderately above average product group, but does not rate with the best premium brands.
The signature of the Naturals formulations is the inclusion of many ingredients not commonly found in lesser-grade dog food, including berries, fruits, and vegetables. Size options are limited, but prices are not budget-breaking.
The general consensus on the web is this is a good quality product, lacking in most of the controversial ingredients found in lower grade foods. Diamond seems to have many brand adherents, though a fair number of detractors, too. Most reviewers, including us, do recommend this brand.
Who Makes Diamond Naturals Dog Food and Where is it Made?
Owned by Schell & Kampeter Inc., Diamond Pet Foods Inc. was founded by two brothers-in-law (Schell and Kampeter, of course!) in 1970. Their first manufacturing plant was established in Missouri, and others followed in California and South Carolina. The company is still family owned and operated, and the products are sold in 100 countries.
Diamond manufactures both dry and wet dog food, as well as treats. They also make dry and canned cat food. The company prides itself on using quality ingredients and “superfoods” in their blends.
This is a video posted by Diamond on their YouTube channel covering the history, manufacturing process, and philosophy of the brand.

Discussion of Most Important Ingredients – Good and Bad
The ingredients in Diamond Naturals dry dog food seem to be generally high grade. There are a few items on the list that merit a closer look. We’ll start with the good stuff:
- Chicken – It’s always good to see a genuine meat product at the top of the list, although much of the volume is lost as the moisture is cooked out of it during the manufacturing process.
- Chicken meal – Fortunately, chicken meal is super-concentrated and full of protein. Having chicken and chicken meal ranked one and two is a good indication that the protein level from meat is probably high.
- Whole grain brown rice – Full of nutrients like B vitamins, minerals and omega-3, this is a grain we don’t mind seeing in dog food.
- Peas – Good source of antioxidants and vitamins.
- Flaxseed – Great source of omega-3, fiber and protein.
- Salmon oil – Primarily a source of omega-3 and omega-6, salmon oil is good for the skin and coat.
- Chicory root – Rich source of inulin, which is in turn a source of dietary fiber, and it’s a prebiotic.
- Chia seed – A good source of omega-3, and a protein boost, as well.
- Pumpkin – An unusual ingredient, but a good one. A fine source of fiber; some dog owners use it to clear up constipation.
- Quinoa – A gluten-free source of fiber.
- Coconut – Another uncommon ingredient, but not an unwelcome one. Medium-chain triglycerides may boost cognitive function.
Now, some things were less happy to see:
- Natural flavour – This is a very vague ingredient, and could be made of almost anything. The inherent flavour of the food ingredients should be enough in a good dog food.
- Fish meal – Although “meal” ingredients are actually quite good, it would be better to know what kind of fish is being used, as not all fish are created equal.
- 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.
There are a lot of fruit and vegetable ingredients in this dog food, which is good as far as added vitamins and nutrients go. However, it does beg the question, how much of the protein is being derived from meat, and how much is from plant material? One would prefer to see more meat, and a few fruits and veg in a supporting role.

Diamond Naturals Dog Food Reviews
Diamond Naturals Dry Food for Adult Dogs
This blend is available in beef & rice, chicken & rice, and lamb meal & rice formulations. All three are advertised as using “real” meat protein, and protein levels range from 23-26 percent. Corn, wheat, and soy are absent from each selection. As with all the Naturals products, this trio is enhanced with probiotics and “superfoods.”
Nutrients seem to be plentiful in all three blends, and there are many quality ingredients like papaya, spinach, carrots and coconut. Unfortunately, we also find natural flavor and salt. Fish meal is also present in all three. What kind of fish? Who knows?
Size selection is extremely limited: only 6 Ounce and 40 Pounds to choose from. Though 40 Pounds is usually a good, economical size, it would be nice to see more variety, as 6 Ounce is only useful as a sample for a small dog.
- Not much grain-filler
- Many nutritious non-meat ingredients
- Good variety of unusual “superfoods”
- Includes salt and other undesirable ingredients
- Only comes in one practical size
- A large portion of the protein may be coming from non-meat sources
Diamond Naturals Chicken Flavour for Large Breed Adult Dogs
If you’ve got a king-sized dog at home, you may be interested in this formulation for Large Breeds. This blend has less fat than Diamond’s standard adult offerings, which should nicely compensate for an increased appetite. Additionally, there are special additives to support bone and joint health, as well as healthy skin and coat.
As with all the Naturals blends, there are plenty of nutritious foods to be found including coconut, kale, blueberries, spinach, and carrots. Regrettably, there is also the ubiquitous inclusion of salt and natural flavor.
As with the previous offering, you can only get this in a 6 Ounce pouch or a 40 Pound bag. Large Breed owners may have wished to see a larger bag for a larger appetite.
- A little more protein, a little less fat
- Tailored to the needs of Large Breeds
- Varied sources of nutrition
- Salt. Why did it have to be salt?
- Big dog, small bag
Diamond Naturals Dry Food for Adult Dogs, Extreme Athlete Chicken and Rice
If you have a Lab like mine, this probably isn’t the food you need! Packed with extra protein, extra fat, and extra calories, this blend is made for very active dogs who have the energy to burn it all off. Like the Large Breed formula, this stuff is supposed to encourage healthy bones and joints, which is great for a high impact athlete.
Again, all the high-quality, nutrient-rich fruits, berries, and veg are represented, as they are in all Naturals formulations. Sadly, salt, and some vaguely described ingredients are also present. I’m fine with fish for dogs, I’d just like to know what kind of fish it is.
Same as the previous two reviews, this blend only comes in the tiny 6 Ouncer, or 40 Pounds. Then again, your average high energy dog is probably only eating a couple of cups a day, so size may not be an issue.
- Provides extra energy for dogs on the move
- Many quality ingredients
- Lots of chicken
- Did I mention salt?
- White rice and barley are both in the top 5 ingredients, and these are not quality grains (although rice does provide an energy boost)
What Others are Saying
The good folks at DogFoodAdvisor are generally positive about Diamond Naturals, although they do note that the protein is only derived from a moderate amount of meat. They take no real issue with most of the ingredients, and ultimately conclude it’s an above-average dry dog food.
RATING: 4 Stars (out of 5)
Dog Food Guru
This site chose to focus on the Extreme Athlete blend. Overall, they thought it was appropriately formulated for very active dogs. However, they are not fans of cellulose as an ingredient, and warn it could cause flatulence.
RATING: 4.5 Stars (out of 5)

Our Diamond Naturals Dog Food Rating
Diamond Naturals by Diamond Pet Food offers dog owners a better-than-average dry kibble for a decent price. There are many intriguing, high-quality ingredients used, and each blend offers a very good level of nutrition. Meat-derived protein options and flavor profiles are limited, but the majority of dogs will likely eat this food readily.
The company seems committed to being a real player in the market, and has a nice online presence with a homey feel. The blog is right up-to-date; it’s nice to see digital marketing not treated as an afterthought.
I have some concerns with the company and recalls, however. Although it has been almost five years since the last one, it was widespread and impacted many brands. While one hopes to avoid a repeat, it might still linger in the back of some consumers’ minds.
There are some ingredients I’m not too fussy about in these blends, and the number of poor ratings and complaints on Amazon do concern me to some degree. However, it is nice to see the variety of specialized formulas available.
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. We do recommend Diamond Naturals and Diamond Naturals Grain-free. Please note this review does not cover Diamond’s standard line of dry kibble.
