Diamond canned dog food receives the Advisor’s second-highest tier rating of 4 stars.
The Diamond product line includes three canned dog foods.
However, since we’re unable to locate AAFCO nutritional adequacy statements for these dog foods on the Diamond website, it’s impossible for us to report specific life stage recommendations for these recipes.
The following is a list of recipes available at the time of this review.
- Diamond Lamb and Rice
- Diamond Chicken and Rice
- Diamond Beef and Rice (3.5 stars)
Diamond Lamb and Rice canned dog food was selected to represent the others in the line for this review.

The first ingredient in this dog food lists 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.1
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.2
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 vitamins and minerals added to this product are not detailed sufficiently here to permit us to judge their quality.
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.
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%.
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 notable amount of meat.
Diamond canned dog food is a meat-based wet product using a notable amount of named meats as its main sources of animal protein, thus earning the brand 4 stars.
Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content.

Rice ingredients can sometimes contain arsenic. Until the US FDA establishes safe upper levels for arsenic content, pet owners may wish to limit the total amount of rice fed in a dog's daily diet.
