The first ingredient in this dog food is lamb. Lamb is considered “the clean flesh derived from slaughtered” lamb and associated with skeletal muscle or the muscle tissues of the tongue, diaphragm, heart or esophagus.2

Lamb is naturally rich in all ten essential amino acids required by a dog to sustain life.

The second item is lamb broth. Broths are nutritionally empty. But because they add moisture to a dog food they are a common finding in many canned products.

The third ingredient lists lamb liver. This is an organ meat sourced from a named animal and thus considered a beneficial component.

The fourth ingredient is rice flour. Rice flour is made from either white or brown rice and is considered a gluten-free substitute for wheat flour.

The fifth ingredient is dried egg product, a dehydrated form of shell-free eggs. Quality can vary significantly. Lower grade egg product can even come from commercial hatcheries — from eggs that have failed to hatch.

In any case, eggs are easy to digest and have an exceptionally high biological value.

The sixth ingredient includes fish meal. Because it is considered a meat concentrate, fish meal contains almost 300% more protein than fresh fish itself.

Fish meal is typically obtained from the “clean, dried, ground tissue of undecomposed whole fish and fish cuttings” of commercial fish operations.3

Unfortunately, this particular item is anonymous. Because various fish contain different types of fats, we would have preferred to have known the source species.

The seventh ingredient is beet pulp which can be a controversial item, a high fiber by-product of sugar beet processing.

Some denounce beet pulp as an inexpensive filler while others cite its outstanding intestinal health and blood sugar benefits.

We only call your attention here to the controversy and believe the inclusion of beet pulp in reasonable amounts in most dog foods is entirely acceptable.

The eighth ingredient is lamb meal, another protein-rich meat concentrate.

From here, the list goes on to include a number of other items.

But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of this product.

With one notable exception

The minerals listed here do not appear to be chelated. And that can make them more difficult to absorb. Non-chelated minerals are usually associated with lower quality dog foods.

Diamond Canned Dog Food
the Bottom Line

Judging by its ingredients alone, Diamond canned dog food looks like an above-average wet product.

But ingredient quality by itself cannot tell the whole story. We still need to estimate the product’s meat content before determining a final rating.

The dashboard displays a dry matter protein reading of 41%, a fat level of 27% and an estimated carbohydrate content of 24%.

As a group, the brand features an average protein content of 41% and a mean fat level of 27%. Together, these figures suggest a carbohydrate content of 24% for the overall product line.

And a fat-to-protein ratio of about 67%.

Near-average protein. Above-average fat. And below-average carbs as compared to a typical canned dog food.

Free of any plant-based protein boosters, this looks like the profile of a canned dog food containing a moderate amount of meat.

Bottom line?

Diamond is a meat-based canned dog food using a moderate amount of chicken, beef or lamb as its main sources of animal protein, thus earning the brand 4.5 stars.

Highly recommended.

Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content and (when appropriate) their fat-to-protein ratios.
