Nulo Dog Food Buying Guide

Company Information

The story of Nulo is one of dedication and commitment by a loving pet parent to provide his beloved pet with only the best. After careful analysis of the pet food brands available in the market, the corporate guy-turned pet care enthusiast and business owner found that more and more pets are getting overweight because of the preponderance of pet food that were filled with more than 40% fillers. Additionally, some so-called high-protein dog foods actually contain more plant-based proteins than meat- or animal-based proteins. As such, he sought to change all that by forming Nulo.

Nulo as a dog food brand emphasizes animal-based proteins as the foundation of good canine nutrition. The brand works with leading veterinarians, clinical animal nutritionists, and food formulators to come up with recipes that put primacy to animal-based proteins while also adding low-glycemic and non-allergenic ingredients into the mix. The result is a dog food that is not only complete and well-balanced, but also provides stable energy source, rich supply of easily digestible animal-based proteins, and none of the worrisome allergens.

Why Choose this Brand?

If you want to give your pet dog food that comes with high-quality, hypoallergenic animal-based protein as its principal ingredient, the Nulo dog food is definitely for your pet. The brand always strives to emphasize the primacy of animal meats as the foundation of optimum dog nutrition.

Its formulations do not contain these ingredients making sure your pet has a safer, gentler tummy and healthier skin, coat, and digestive system.

Ingredient Analysis

Without a doubt, Nulo dog food deserves the right to be called one of the best. However, it would be unjust for us to make such statements without making some strong points for the brand. Here’s what we have found out looking at and analyzing the Nulo dog food ingredients.

  • Above average protein

On the average, Nulo comes in with a crude protein content of about 30% for its dry food varieties and 10% for its canned or wet versions. When the moisture content of these formulations is taken into consideration, the dry food formula will come out with 33.33% protein on a dry weight basis. Its canned version, on the other hand, will come up with 45.45% protein content on a dry weight basis. When compared with other specialty brands you may find that Nulo is at par with some of them, although there are definitely other products that provide a much better proportion of proteins than Nulo does.

However, this isn’t the end of the story. As one of the principal reasons for establishing the company, more than 80% of Nulo’s proteins come from animal meats and other animal-based ingredients. We have seen products with substantially higher protein contents than Nulo’s but more than 50% of the proteins in these products are actually sourced from plant ingredients. Again, we don’t have anything against plants as ingredients. We just don’t necessarily believe that they can provide the most complete range of essential amino acids that are critical to a dog’s optimum development. That being said, while it is true that Nulo’s protein content may pale in comparison to other high-protein dog diets, you can be sure that its proteins are from animal sources.

Another point worth mentioning is that the brand always names its ingredients especially its proteins. Nowhere on the label will one can see vague terms such as “animal” or “meat” or even “poultry”. The brand doesn’t hide the ingredients that it uses. On that note, it doesn’t even include chicken in its formulations. Everyone talks about food allergies. Unfortunately, many overlook the fact that beef and chicken are two of the most allergenic proteins in the land. Substituting this with turkey, salmon, trout, and menhaden fish among others is something noteworthy of the brand.

  • Low to Moderate fat

Averaging the 4 dry dog food products of Nulo in this list, we can come up with an average fat content of 13.25% while its canned version comes in with 6%. This can be adjusted to account for moisture leading to a dry weight protein content of 14.7% for the dry dog food formulas and 27.3% for the canned variety. If one takes a look at the dry dog formulation, it is well below the 18 to 20 percent range of most dry dog food brands.

This can be attributed to the brand’s choice of leaner meats like turkey, trout, and salmon as its principal ingredients. Since animal ingredients typically contain both proteins and fats, the denser the muscles the lesser is the fat content.

However, one should also take a look at what salmon and the other ocean fishes bring to the mix. These are rich in omega-3 fatty acids which can help in the enhancement of a variety of physiologic processes in the dog’s body.

  • Low carbs

Considering the protein and fat content of Nulo dry dog food varieties, we can compute for its carbohydrate content on a dry matter basis as 42.3%. For its canned version, carbs only constitute about 27.25% of the ingredients. Overall, one can say that Nulo dog food contains low to moderate amounts of carbs.

The best part of this is that it never uses high glycemic and allergenic ingredients such as wheat, soy, and corn. It also does away with a lot of fillers. For instance, its Lamb & Chickpeas recipe only contains chickpeas, yellow peas, and sweet potato as the added ingredients although there are additional fruits in minimal amounts.

  • Micronutrients

Whenever appropriate, Nulo dog food makes sure that the formula contains other micronutrients and nutraceuticals needed to effect a desired change in the dog’s physiology. For example, l-carnitine is highlighted in weight management diets while chondroitin and glucosamine are fortified in formulas for seniors and other dog conditions that require strengthening of the joints. DHA and EPA are also great for puppies. One thing is certain, Nulo more than complies with the requirements of AAFCO; it exceeds them.

Pros & Cons

  • High protein content sourced from high-quality animal proteins as the first ingredient
  • All animal proteins and other ingredients are named or identified
  • Low to moderate amounts of carbohydrates, mostly lentils
  • Doesn’t contain soy, corn, wheat, gluten, and other potentially allergenic grains
  • Doesn’t contain chicken as protein; may contain chicken fat, however
  • All formulations come with probiotics
  • Whenever appropriate, glucosamine and chondroitin are added
  • Good ratio of omega-3 and omega-6 fatty acids
  • No artificial ingredients such as preservatives, flavor enhancers, and coloring
  • Exceeds AAFCO minimum nutrient recommendations for dogs
  • Very pricey
  • Not as readily available as leading brands
  • Nulo dog food is a high protein, moderate-calorie, low-carb formulation that takes into consideration the unique developmental stages of dogs. It doesn’t use chicken as well as any of the allergenic grains that many pet parents are worried of. Despite its hefty price tag, Nulo dog food makes for a great diet to feed to modern pets.
