Diamond Naturals Dog Food Review – Quality or Not?

Diamond Naturals claims to offer premium quality dog food at an affordable price. But with so many options on the market, how can you be sure it provides good nutrition for your pup? This comprehensive review takes an in-depth look at Diamond Naturals dog food to see if it delivers on quality.

An Overview of Diamond Pet Foods

Diamond Pet Foods produces four different lines of dog food:

  • Diamond Naturals – Their premium natural line
  • Diamond – Their standard line
  • Diamond Care – Formulated for senior dogs
  • Diamond Naturals Grain-Free – Protein-rich and grain-free recipes

The company sources ingredients from trusted suppliers around the world to formulate what they describe as “super premium” dog food.

Diamond Pet Foods has four manufacturing facilities across the USA where they make their own food. They say this allows for quality control and food safety.

The brand is affordable compared to other premium and grain-free dog foods. But does lower cost mean lower quality? This review will analyze the pros and cons of Diamond Naturals dog food.

Diamond Naturals Dog Food Product Line

The Diamond Naturals standard line includes both dry kibble and canned food. There are formulas for puppies, adults, and seniors. The primary ingredients and sources of protein include:

  • Chicken: Deboned chicken, chicken meal
  • Lamb: Lamb meal, lamb
  • Beef: Beef meal, ground beef
  • Fish: Salmon meal, whitefish meal

The grain-free line also includes dry and wet food. Instead of grains, they use ingredients like lentils, peas, and tapioca as carb sources.

There are grain-free formulas with unique proteins like bison, wild boar, duck, and venison. Some recipes are also designed for sensitive stomachs.

In addition to traditional recipes, they offer freeze-dried raw food and limited ingredient diets.

Overall, Diamond Naturals provides a diverse product line suitable for most dogs. The inclusion of novel proteins is a nice bonus not always found in cheaper foods.

Diamond Naturals Dog Food Ingredient Analysis

Analyzing the ingredient lists reveals more about the quality of these recipes.

Positive Ingredients

  • Named meat meals: Chicken meal, lamb meal, salmon meal. Meals contain concentrated protein.
  • Whole meats: Fresh chicken, lamb, beef, fish. Provides natural protein.
  • Digestible carbs: Brown rice, barley, peas, sweet potatoes. Good sources of carbs.
  • DHA for brain development: Important nutrient, especially for puppies.
  • Prebiotics and probiotics: Support healthy digestion and immunity.
  • Chelated minerals: Zinc, copper and other minerals in a bioavailable form.
  • Natural flavorings: Make the food more enticing for picky eaters.
  • Antioxidant-rich fruits and veggies: Rich in vitamins, minerals and phytonutrients.

Questionable Ingredients

  • Pea protein: Cheaper plant-based protein boosting protein percentages.
  • Mixed tocopherols: A less natural form of vitamin E.
  • Salt: Added to enhance flavor but unhealthy in excess.
  • Caramel coloring: Artificial coloring agent with controversial health effects.

Controversial Ingredients

  • Corn: Cheap grain filler linked to allergies and intolerance in some dogs.
  • Soybean meal: Cheap protein that can trigger gas and bloating.
  • BHA: Preservative with possible links to cancer. Banned in human food in some countries.

The ingredient lists could be improved by removing corn, soy, caramel coloring, BHA, and excess salt.

More emphasis on quality meats vs plant proteins would be better. But overall, the ingredients are average quality for cheaper dog foods.

Diamond Naturals Dog Food Nutritional Analysis

Next let’s analyze the guaranteed analysis percentages for basic nutrients:

Diamond Naturals Chicken & Rice Formula for Adult Dogs

  • Protein – 21%
  • Fat – 12%
  • Fiber – 4%

Diamond Naturals Grain-Free Chicken & Sweet Potato Formula for Adult Dogs

  • Protein – 25%
  • Fat – 15%
  • Fiber – 4%

These meet AAFCO standards for complete and balanced nutrition. The grain-free formulas tend to be higher in protein and fat, similar to other premium brands.

However, critics argue the protein percentages can be misleading. This is because they include cheaper plant protein boosters like peas.

Meat should ideally be the #1 ingredient and source of protein. But with Diamond Naturals, plant meals usually top the ingredients before the first meat.

Taste & Texture: Do Dogs Like Diamond Naturals?

Taste is subjective, but most dogs seem to love the flavor of Diamond Naturals. The kibble is crunchy but not too hard. It’s smaller in size which makes it easy to chew.

The formulas with fresh meats like chicken, lamb, or fish are extra enticing. Dogs gobble up the canned food too.

Some finicky pups may turn their nose up at the standard chicken and rice recipes. But the unique proteins and grain-free lines offer more novelty.

Adding warm water, bone broth, or wet food on top can make it even tastier. This helps release aroma and flavor to excite picky eaters.

Diamond Naturals Dog Food Safety Issues

Diamond Pet Foods has faced some serious safety issues over the years:

  • 2005: Dogs died after eating Diamond food tainted with aflatoxin mold. Plant identified as source.
  • 2012: Salmonella outbreak linked to Diamond plant sickened dozens of pets. Plant shut down for cleaning.
  • 2018 – 2019: Taurine deficiencies and DCM connected to grain-free dog foods, including some Diamond recipes.

These incidents hurt consumer confidence in Diamond’s quality control. But the brand claims they’ve implemented stricter safety procedures and testing since then.

They source ingredients from trusted suppliers and test final products for safety. All their facilities follow strict processes for food safety.

But it’s understandable if some owners are still wary, given the history. These issues may be behind Diamond Naturals. But quality problems can occur with any brand.

Is Diamond Naturals Worth the Price?

Diamond Naturals costs slightly less than big name premium foods like Blue Buffalo but a bit more than budget brands like Purina Dog Chow.

Saving money is nice. But is it worth compromising on quality?

Key Considerations:

  • Made in their own US facilities for safety. But history of recalls.
  • Quality ingredients but not as natural as many premium foods.
  • Meat meals over whole meats. Includes some fillers.
  • Most dogs do well but inconsistencies between batches.
  • Cheaper than most premium foods but costs more than basic grocery brands.

The price reflects an in-between level of quality. There are pros and cons to this brand.

Diamond Naturals can work well for healthy dogs without specialized needs. But it may not be the best choice for dogs with sensitivities requiring very high quality.

Those seeking premium nutrition may want to spend more on brands using fresher, more natural ingredients.
