About Diamond Pet Products

Diamond Naturals Grain-Free dog food is manufactured by Diamond Pet Products, a large U.S.-based manufacturer that also makes other popular dog food brands. Started in 1970, Diamond Pet Products has fifty years of experience in making dog food and has often updated its safety and quality standards over time. However, they still have had some fairly significant recalls that may make you want to avoid this entire line.

Which Types of Dogs is Diamond Naturals Grain-Free Dog Food Best Suited For?

The grain-free version of Diamond’s Natural line is a good option for dogs just switching over to a grain-free diet. It’s relatively inexpensive and uses higher-quality ingredients than other dog food brands at the same price, so you won’t have to worry about too many filler ingredients. It’s also a good choice if your dog can’t have poultry as well as grains, with salmon being the main source of protein.

Which Types of Dogs Might Do Better with a Different Brand?

If your dog needs a grain-free diet, this option is fine. Otherwise, Diamond Naturals grain-inclusive recipes will work just as well for your dog. It’s important to note that any limited or restricted diet should be carefully monitored, so consult with your vet if Diamond Naturals grain-free is right for your dog.

  • May – FDA recalled select bags of small breed dry dog food due to possible salmonella contamination.
  • May – FDA sent out a massive recall of all Diamond Pet Foods for possible salmonella

Discussion of the Primary Ingredients (Good and Bad)

Salmon (Good) ✅

Salmon is the first ingredient of Diamond Naturals Grain-Free dog food, which is a great first ingredient to have in a dog food recipe. Not only is it a great source of protein, but it’s also rich in fatty acids that Omega-3 and Omega-6. Although whole meats can greatly reduce in size after processing, it’s still a high-quality protein source that rarely disappoints.

Fish Meal (Good) ✅

Diamond Naturals Grain-Free dog food lists fish meal as the second ingredient, giving the kibble an additional protein-rich ingredient. Fish meal is a rendered meat product that uses the clean parts of the fish and sounds like something that should be skipped, but it has more protein than whole meats do. Meat meals shouldn’t be confused with by-products, which are cheap alternatives to fresh ingredients.

Lentils & Peas (Potential Issues)

Lentils, peas, and legumes are considered controversial from their use in dog food due to the recent rise in canine heart disease in dogs eating these ingredients, so this is something to consider when buying any dog food with peas, lentils, and legumes. While the evidence is still somewhat lacking, ask your vet if you should avoid these ingredients with your dog specifically. Some dogs have no problem with peas and lentils, but the recent cases of heart conditions may have you questioning if these ingredients are safe.

Flaxseed (Okay) ✅

Flaxseed can be an excellent source of fatty acids and amino acids, but only if your dog can easily digest it. There’s nothing wrong with flaxseed or flax blends for fiber and digestive support, but it can be harsh for dogs with sensitive stomachs. This ingredient is generally considered safe, so your dog should be fine as long as it can digest flax.
