The first ingredient in this dog food is chicken. Although it is a quality item, raw chicken contains about 80% water. After cooking, most of that moisture is lost, reducing the meat content to just a fraction of its original weight.

After processing, this item would probably account for a smaller part of the total content of the finished product.

The second ingredient is chicken meal. Chicken meal is considered a meat concentrate and contains nearly 300% more protein than fresh chicken.

The third ingredient is brown rice, a complex carbohydrate that (once cooked) can be fairly easy to digest. However, aside from its natural energy content, rice is of only modest nutritional value to a dog.

The fourth ingredient is oatmeal, a whole-grain product made from coarsely ground oats. Oatmeal is naturally rich in B-vitamins, dietary fiber and can be (depending upon its level of purity) gluten-free.

The fifth ingredient is peas. Peas are a quality source of carbohydrates. And like all legumes, they’re rich in natural fiber.

However, peas contain about 25% protein, a factor that must be considered when judging the meat content of this dog food.

The sixth ingredient includes turkey meal, another protein-rich meat concentrate.

The seventh ingredient is chicken fat. Chicken fat is obtained from rendering chicken, a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.

Chicken fat is high in linoleic acid, an omega-6 fatty acid essential for life. Although it doesn’t sound very appetizing, chicken fat is actually a quality ingredient.

The eighth ingredient is dried sweet potato. Sweet potatoes are a gluten-free source of complex carbohydrates in a dog food. They are naturally rich in dietary fiber and beta carotene.

The ninth ingredient is pea fiber, a mixture of both soluble and insoluble dietary fiber derived from pea hulls. Aside from the usual benefits of fiber, this agricultural by-product provides no nutritional value to a dog.

From here, the list goes on to include a number of other items.

But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of this product.

With six notable exceptions

First, brewers yeast can be a controversial item. Although it’s a by-product of the beer making process, this ingredient is rich in minerals and other healthy nutrients.

Fans believe yeast repels fleas and supports the immune system.

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.

In addition, a vocal minority insists yeast can increase the risk of developing the life-threatening condition known as bloat. However, this is a claim we’ve not been able to scientifically verify.

In any case, unless your dog is specifically allergic to it, yeast can still be considered a nutritious additive.

What’s more noteworthy here is that brewers yeast contains about 48% protein, a factor that must be considered when judging the actual meat content of this dog food.

Next, flaxseed is one of the best plant sources of healthy omega-3 fatty acids. Provided they’ve first been ground into a meal, flax seeds are also rich in soluble fiber.

However, flaxseed contains about 19% protein, a factor that must be considered when judging the actual meat content of this dog food.

In addition, this food contains dried egg product, a dehydrated form of shell-free eggs. Quality can vary significantly. Lower grade egg product can even come from commercial hatcheries — from eggs that have failed to hatch.

In any case, eggs are easy to digest and have an exceptionally high biological value.

Next, we find menhaden oil. Menhaden are small ocean fish related to herring. Their oil is naturally rich in the prized EPA and DHA type of omega-3 fatty acids, two high quality fats boasting the highest bio-availability to both dogs and humans.

What’s more, in their mid-depth habitat, menhaden are not as likely to be exposed to mercury contamination as is typical with deep water species.

In addition, chicory root is rich in inulin, a starch-like compound made up of repeating units of carbohydrates and found in certain roots and tubers.

Not only is inulin a natural source of soluble dietary fiber, it’s also a prebiotic used to promote the growth of healthy bacteria in a dog’s digestive tract.

And lastly, the minerals listed here do not appear to be chelated. And that can make them more difficult to absorb. Non-chelated minerals are usually associated with lower quality dog foods.

Nulo Naturals Dog Food
The Bottom Line

Judging by its ingredients alone, Nulo Naturals looks like an above-average dry dog food.

But ingredient quality by itself cannot tell the whole story. We still need to estimate the product’s meat content before determining a final rating.

The dashboard displays a dry matter protein reading of 30%, a fat level of 16% and estimated carbohydrates of about 46%.

As a group, the brand features an average protein content of 30% and a mean fat level of 16%. Together, these figures suggest a carbohydrate content of 46% for the overall product line.

And a fat-to-protein ratio of about 52%.

Near-average protein. Near-average fat. And below-average carbs when compared to a typical dry dog food.

Even when you consider the protein-boosting effect of the peas, brewers yeast and flaxseed, this looks like the profile of a kibble containing a moderate amount of meat.

Bottom line?

Nulo Naturals Dog Food is a plant-based kibble using a moderate amount of named meats and meat meals as its main sources of animal protein, thus earning the brand 4.5 stars.

Highly recommended.

    Interesting thing I found out, when my local pet supply stopped carrying Nulo. Supposedly stores have to buy direct from Nulo, there is no distributor. When buying direct, they have to buy an enormous minimum. For someone as small as our local supply, it’s extremely prohibitive on many levels, which is why they discontinued. Bummer. They picked up the Go! line but I’m not as excited about it (more expensive, and I have to feed more).

  • Storm’s Mom

    It looks decent.. brown rice, oatmeal, millet AND chickpeas are a lot of filler, though, and the protein is at the very low end of what I would feed (and some of that protein comes from the chickpeas, which is not ideal). It doesn’t have any ingredients that would be red flags for me, but I’d take the Endurance formula over the Balance any day. Balance looks like a 4 star food, Endurance a 5 star.

  • Ashe

    How good do you think the balance formula would be?

  • Ashe

    Alright, thanks. I’ll do that.

  • Storm’s Mom

    Just looked up this Endurance formula – wow! No chicken, no grains, no potato!! I’d agree that it looks like a 5 star formula. Would looooooooooove to try it!! …if only it were actually available here *siiiiiigh* 🙁 Maybe one day….

  • Hound Dog Mom

    The Endurance formulas looks great. I’m sure Dr. Mike will get around to reviewing it eventually, I know there’s a long list of foods waiting to be reviewed. However, looking at the ingredients and general analysis I’m almost certain it will receive 5 stars.

  • Hound Dog Mom

    Hmm…looking at it I would say probably 3-3.5 stars. It’s fairly low protein and extremely low in fat (so low that I wouldn’t consider feeding it long term). The Lifestyles Balance and the Naturals formulas look much better. Why not feed one of those and just give your dog less? There’s no reason to feed a food specifically designated for weight loss to an overweight dog, just feed them less of a good quality dog food not designed for weight loss.

  • Ashe

    I wish you guys had a review on Nulo Trim. I want to know if it’s a good dog food I’m feeding my dog.

  • threemutts

    The current dry review is the Nulo Naturals. The current wet review is the Nulo Lifestyles. I wish they reviewed both versions, too!

  • threemutts

    We switched to feeding our dogs Nulo Endurance after we used a sample bag as treats and our dogs responded well. Curious how it fares? 3:2 protein sounds promising and the ingredients look decent, but I’m no nutrition pro. Looks like the Lifestyles formulas are missing altogether from the reviews? Perhaps they’re too new.

  • Einstein and Edison

    Can you review the Nulos Naturals line? or Is this it and the lifestyles (canned) the only lifestyles type.

    This dog food is too wet! I have to add dry dog food to absorb much of the moisture.

  • Jacqeline Paredi

    I have 2 yorkies (medium and large size) and have been feeding them Nulo for 3 months or so. At first they inhaled it, but then they became a little more picky about eating it. They both had been very thin after having been fed a clean raw commercial dog-food diet of raw chicken and rehydrated vegetables among other ingredients. My larger of the two has grown to a good weight, but the smaller one has become pudgy. They eat when they are hungry and leave much food unconsumed. A good thing is that their feces are relatively small. (Quite a change from the raw diet.) So I have a mixed review here.
