NutriSource Dog Food Buying Guide

Company Information

NutriSource dog food is made by Tuffy’s Pet Foods which was established in 1964 by Darryl Nelson and his son, Kenny. The company is now on its 54thyear of operation and is now headed by the third generation of the Nelson family, Charlie, the grandson of Darryl. Tuffy’s Pet Foods is a perfect example of what a family-owned business is like. Being located in Perham, Minnesota, the business thrives on its partnership with the families in the community that have become the local producers and growers of the finest quality ingredients that eventually find their way into the various formulations of the pet food brand.

Being a family-run small business, Tuffy’s is all about integrity, compassion, and the indomitable sense of community that have become the cornerstones of their existence and what can be seen in the products that they formulate. One can feel this sense of community in the dog food products as something that these families in Perham would personally give to their dogs.

The company makes a variety of dog and cat foods and treats in various regional themes such as Prairie, Woodlands, High Plains, Heartland, Grate Northwest, and Mediterranean. There are also condition-specific diets like Weight Management and Performance. Of course, there are varieties for puppies, seniors, small breeds, large breeds, and ingredient-specific diets.

Aside from formulating its pet food products using high quality ingredients, Nutri Source is also one of those few brands that have yet to experience a product recall. Considering that it’s been around for more than half a century, this is quite remarkable.

Why Choose this Brand?

Firm believers of the animal-protein-first philosophy of dog food will definitely love this brand as it places emphasis on the importance of using named and clearly identifiable animal proteins in all of its formulas. If you’re a vegan who also wants your dog to be vegan, then this is clearly not for you.

Pet lovers who don’t like having wheat, corn, or soy in the food that they give to their dogs will also rejoice with this brand. It comes in grain free formulation that helps ensure friendlier tummies. This is in addition to the carefully selected ingredients for easier digestibility.

If you need dog food that already comes embedded with probiotics for your pet’s optimum digestive and immune system functioning, then this brand is also worthy of choice. In addition to the probiotic organisms that many of its formulations contain, there is also a number of substances that can provide for additional benefits such as healthier skin and coat, better immune system, and improved neurologic functioning.

Ingredient Analysis

There were 5 NutriSource dog food products that we have included in this NutriSource dog food review. While the brand itself has numerous products that come with a variety of nutrient profiles, we shall limit our ingredient analysis to what we have in this list. An analysis of the NutriSource dog food ingredients reveals the following.

  • Average protein content

As expected, there is a great disparity in the protein content for the dry and wet food versions of this brand. For its dry variant, it averages about 27.25% or 30.27% when the 10% moisture has been taken off the computation. The wet or canned variety offers a much better protein profile of 40.9% as dry matter. Unfortunately, there are brands that offer way better protein profiles.

We have to point out that, while these levels of proteins are above the minimum required by AAFCO and NRC, they do not reflect what we believe to be a protein-rich diet that is essential for dogs. Some good quality dry dog food brands come with at least 35% in dry matter basis while wet varieties come in the higher 40s or mid-50s.

This is quite baffling since two to three of the products’ top 5 ingredients are actually animal proteins. This somehow leads us to believe that the brand is not really a primarily animal ingredient-based dog food formulation, but rather plant-based. You’re more than welcome to dispute this, but it’s the only valid conclusion we can arrive at.

Ancestral dogs thrived on whole prey that did not contain carbohydrates, only proteins and fats. They do occasionally eat vegetables, fruits, and other carbs, but only when prey isn’t available. Now, you may contend that dogs have already evolved so much that they can now eat basically anything that we give them. Sadly, Mother Nature has not changed the structure of the dog’s gut which, up to the present time, is still that of a predator.

On the bright side, NutriSource dog food always makes sure that the first ingredient is a named animal protein. This is unlike some popular brands that put wheat, rice, or even corn as its first ingredient. There were a few instances that an animal ingredient was not named, however. We noted the use of “fish” meal in a few of the products reviewed. We’re wondering what kind of “fish” is exactly in the formula.

  • Average to above average fat content

The wet dog food version of NutriSource has one of the highest fat contents we have seen on a dry matter basis. This is computed at 36.36% while its dry dog food version comes in at an average 16.5% or 18.3% as dry matter. As far as the dry dog food formula is concerned, Nutri Source is well within industry average. However, it’s the wet variety that we’re a bit concerned about. As such, we do strongly recommend that the canned version be used more as a food topper than a full meal.

The good news is that they do manage to provide near-ideal ratios of omega fatty acids. And while neither AAFCO nor NRC recognizes these as essential nutrients, they do provide a host of benefits to your pet, especially for puppies. It’s also good for adults as a means to maintain the health of the skin, coat, immune system, and the heart.

Cute dog

  • Low to above average carbohydrates

We mentioned above that we have this feeling that NutriSource is more of a plant-based dog food with moderate amounts of animal ingredients. The reason for this is that, when we computed for its carbohydrate content factoring the protein and fat components of the dog food brand, we came up with a carbohydrate content of 22.74% for the canned version and 51.43% for the dry version. We don’t see any issue with the canned variety. It’s the dry dog variants that we are primarily concerned about.

While there are some who say that dogs can eat anywhere between 30 and 70 percent carbohydrates, this doesn’t reflect their evolutionary diet at all. The 30-70 percent is more like what humans today consume.

On a positive note, the brand does away with wheat, corn, and soy as well as potatoes and other high glycemic foods. This should be good news for the pet parents of dogs that are predisposed to diabetes.

  • Micronutrients

NutriSource dog food products meet the nutrient requirements specified by the NRC and AAFCO. Whenever appropriate, the brand also includes chelated minerals to improve the nutrition profile. Probiotics, prebiotics, glucosamine, and chondroitin are also included in many of the formulations.

  • Moderate amounts of protein
  • Uses high quality, named animal proteins in each formulation
  • Includes prebiotics and probiotics in dry dog food formulations
  • Doesn’t use plain water as moisture for wet food varieties
  • Doesn’t contain wheat, corn, and grain
  • Many products don’t contain high glycemic foods like potatoes
  • Includes chondroitin and glucosamine in many formulations
  • Adheres to AAFCO and NRC recommendations for dog nutrition
  • Quite difficult to source as the brand is more geared towards local pet food stores, although they now have presence in some online commerce platforms
  • A few products come with an unnamed protein such as “fish” meal
  • Typically pricier than most
