Diamond Pet Foods is one of the largest pet food manufacturers in the United States, producing dog and cat food under several different brand names. With a wide selection of dry and wet foods spanning multiple product lines, Diamond offers extensive options for pet parents seeking quality nutrition.

But how does Diamond dog food truly measure up? This comprehensive review will analyze Diamond’s brand, manufacturing process, recall history, and dive deep into an ingredient analysis and review of some of their most popular dog food formulas.

A Brief Background on Diamond Pet Foods

Diamond Pet Foods has been producing pet food since 1970. Headquartered in Meta, Missouri, they operate four manufacturing facilities across the United States.

The company specializes in producing budget-friendly pet foods sold under various brand names at retail stores globally. Some of their major brand lines include:

  • Diamond: Their standard brand featuring both grocery and premium lines.
  • Taste of the Wild: Grain-free formulations.
  • Kirkland: Budget brand made exclusively for Costco.
  • 4Health: Premium brand made for Tractor Supply Company.

Diamond highlights their focus on quality ingredients and nutritional research. Their facilities have on-site quality control labs and they employ multiple PhD animal nutritionists.

How Diamond Pet Foods are Made

Diamond emphasizes following a carefully crafted production process to create quality pet food:

  • Ingredient Sourcing: Diamond sources ingredients from suppliers around the world, claiming to only select high-quality ingredients that meet their specifications.
  • Quality Control: All ingredients must pass testing in their on-site laboratories before being approved.
  • Formulation: Their PhD nutritionists craft formulas to meet established nutritional standards and profiles.
  • Cooking: They use various cooking techniques including baking, extrusion, and cold forming based on the recipe.
  • Testing: All finished products are tested for nutrients, bacteria, and other quality measures before release.
  • Packaging: Food is packaged in various types of bags or cans then prepared for shipment.

While affordability drives production, Diamond states they do not compromise on safety or nutritional quality.

Diamond’s Recall History

Diamond has encountered some significant recall events over the years:

  • April 2012: Large recall affecting Diamond brands due to potential Salmonella contamination. Multiple production facilities were involved.
  • May 2012: Expanded recall to also include potential mold growth risks.
  • August 2013: Limited recall of Diamond dry dog food due to potential Salmonella problems.
  • November 2015: Recall of select Taste of the Wild formulas due to potential Salmonella issues.

These sizable recalls early on damaged trust in some consumers. Diamond states they have implemented many improved safety procedures across all their plants following these events.

Recent years indicate these measures have been largely successful, with no major events since 2015. But minor recalls still occasionally occur:

  • February 2018: Minor recall of four raw pet food formulas due to potential Salmonella contamination.
  • June 2019: Limited recall of select pig ear treats over Salmonella concerns.
  • May 2021: Recall of several corn-based products due to potential aflatoxin contamination.

Overall, Diamond’s recall volume has decreased dramatically in scale and frequency following their major recall events in 2012-2013. While this history merits caution, their enhanced safety protocols over the past decade do appear largely effective.
