Diamond Dog Food (Canned)

Share

Rating: ★★★★☆

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

We are pleased to note that, unlike many fish meals, this particular item appears3 to be ethoxyquin-free.

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.

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%.

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.

Bottom line?

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.

Highly recommended.

Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content.

    Meagan- i ended up completly switching to taste of the wild also made by diamond, my pitbull wouldnt eat the diamond dry at all anymore and he got tired of the blackwood. The shepherd liked the TOTW to but it upset his stomach.

  • Meagan

    Brian- No problem. :) I have not fed any of the regular Diamond line as I do not agree with some of the ingredients in it. The Diamond Naturals has better quality meat in it so in my opinion it wouldn’t hurt anything to try it with your pups. Just remember to transition slowly over 7 to 14 day period. Also try to mix the wet in really well with the dry, even adding a tsp or so of warm water. I like to use the pate style canned foods, because they are easier to mix with the kibble. Good luck let us know how it goes please.

  • Brian

    Thanks. Hey meagan I was wondering is there a big difference in taste between diamond and diamond naturals? Even when I top off the regular diamond dry he still just picks over it but I have heard diamond naturals is a better dog food do you think he might like the naturals better?

  • http://DogFoodAdvisor.com Mike Sagman

    Hi Brian… Have you tried mixing the wet and dry together. This is called topping and it works for many finicky eaters. For more information, please see our FAQ page and look for the topic, “How to Feed a Dog”.

  • Meagan

    Brian-As long as your dog tolerates it with no GI upset, then it is fine to feed a different brand for dry and wet. I top my dogs Diamond Naturals dry and Exclusive dry mix with any 4 or 5 star wet food. They have had TOTW, 4Health-all formulas, Diamond-Beef and Rice, and Wellness-Duck and Sweet potato can varietys.
    They love meal times.

  • Brian

    I have a 10 month old pitbull on diamond dry and just got a 3 month old german sheperd who was on blackwood dry, it turns out my pitbull likes the blackwood dry more. I was wondering should I switch the wet food to or is ok for him to be one brand dry and a different brand wet?

  • Meagan

    Melissa-Those 4Health chunky styles do not seem to go as far as the pate. I probably won’t buy them again becasue they are also harder to mix. The dogs did love it still, but heck they seem to like all their wet foods. LOL Can’t wait for Mike’s review on the 4Health canned. He said within the next week or so it should be up. BTW the Diamond beef and rice canned is going well with them too. I switch one day Diamond next day Wellness then back to Diamond on 3rd, then the 4th day they get 4Health. Mainly because I have twice the amount of Diamond then the other two brands.

  • melissa

    Meagan-

    They all sell them in cases, but many do not carry more than a case or two that is open on the shelf. If your TSC employee refuses to get you cases, just email TSC and let them know-they have EXCELLENT customer service when it comes to employee not assisting the clients.

  • Meagan

    The TSC I went to does not sell 4health in cases but i still bought twelve. And a couple cans of taste of the wild.

  • Meagan

    I do love the bargains at TSC. I only wish they had more stores. The closest ones to me are an hour and thirty minutes. We have a store called Theisens Farm*Home*Auto, they have about every kind of dog food (and many other pet items) you could ask for lol I love their store, but the closest is also one hour and thirty minutes away. They are not to exxpensive, its about the same price as TSC. I just need to move back to the big towns instead of in the boonies. I love my small towns better than cities unfortunatly.

  • melissa

    Meagan-

    The chicken/rice and the Lamb/Rice are pate style. I buy it by the case, and watch the flyers at the front checkout-when it goes on sale, I buy quite a few cases at a time.

    Its a good place to shop for some better foods if the budget gets tight. Watch their website for upcoming deals/flyers. Everytime you go there, check around the checkout for additional little folded flyers-they frequently hold “pet days” in which there is a coupon for $5 off each bag of food(limit 2) when they first introduced their food(canned) it was 50 cents a can for one day only-I raced over and “rainchecked” 20 cases, lol I still have 2 cases left : )

  • Meagan

    Melissa- I do have one, in fact I was planning on going there tomorrow on my day off. What a coincidence! I have been meaning to get there, because I too think it would be at least 4 star! Wow did not know that it was sometimes on sale. That is a great bargain in my opinion. I have asked Mike about rating it, its on his to do list :) One question can you buy it in cases? And which ones are the pate? They seem easier to mix with the dry. Even though I will most likely buy each formula. Thanks for the tip.

  • melissa

    Meagan-

    Not sure if you have a Tractor Supply around you, but my dogs love the 4Health chicken/rice canned. Its .99c per can, corn/wheat/soy free and seems to be decent(Mike has not rated it yet..course if it comes out a 2 star product, I will be horrified, lol!) Its often on sale for .75 cents per can. They have two “pate” styles and two “chunky style with veggies”..

  • Meagan in Iowa

    Just opened a can of the beef and rice. Patch and Bolt ate it up. I like that it is kind of a pate, its easy to mix with the dry.

  • Meagan

    Erin c- i will be able to let you know in a week. i ordered it on amazon i can not get it around here.

  • erin c.

    These days I like to see products that have very few ingredients and this is one that does.

    Do dogs like the taste of this product?

  • Meagan

    Looks like I will have to order this from online. I was suprised Theisens does not carry it. Unless I overlooked it. Oh well anything for my babies. :)

  • http://DogFoodAdvisor.com Mike Sagman

    Meagan… Flavor only matters to your dog. And I feel certain, almost any quality topper will improve the lamb and rice kibble. Without knowing your dog, it is impossible to say whether the amount is too much or too little.

  • Meagan

    Will it matter what flavor I use to top my dogs food? They eat lamd and rice dry. Also I used the MBW and used my dogs weight with the kcal/can. It says he should get 3 to 3 1/2 cans a day. Isn’t that a little much?
