The first ingredient in this dog food is chicken. Although it is a quality item, raw chicken contains about 80% water. After cooking, most of that moisture is lost, reducing the meat content to just a fraction of its original weight.

After processing, this item would probably account for a smaller part of the total content of the finished product.

The second ingredient is turkey meal. Turkey meal is considered a meat concentrate and contains nearly 300% more protein than fresh turkey.

The third ingredient is brown rice, a complex carbohydrate that (once cooked) can be fairly easy to digest. However, aside from its natural energy content, rice is of only modest nutritional value to a dog.

The fourth ingredient is white rice, a less nutritious form of rice in which the grain’s healthier outer layer has been removed.

The fifth ingredient is chicken fat. Chicken fat is obtained from rendering chicken, a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.

Chicken fat is high in linoleic acid, an omega-6 fatty acid essential for life. Although it doesn’t sound very appetizing, chicken fat is actually a quality ingredient.

The next two ingredients are chicken and lamb meals. Like turkey meal already discussed, these are both considered protein-rich meat concentrate.

The eighth ingredient is tomato pomace. Tomato pomace is a controversial ingredient, a by-product remaining after processing tomatoes into juice, soup and ketchup.

Many praise tomato pomace for its high fiber and nutrient content, while others scorn it as an inexpensive pet food filler.

Just the same, there’s probably not enough tomato pomace here to make much of a difference.

The ninth ingredient is ocean fish meal, another high protein meat concentrate.

Fish meal is typically obtained from the “clean, dried, ground tissue of undecomposed whole fish and fish cuttings” of commercial fish operations.1

Fortunately, Canidae does advise website readers this fish meal is obtained from herring and menhaden, small ocean fish rich in protein and omega-3 fatty acids.

What’s more, in their mid-depth habitat, menhaden are not exposed to mercury contamination as can be typical with deep water species.

We are pleased to note that, unlike many fish meals, this particular item appears2 to be ethoxyquin-free.

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 three notable exceptions

First, we note the inclusion of inulin, a starch-like compound made up of repeating units of carbohydrates and found in certain roots and tubers.

Not only is inulin a natural source of soluble dietary fiber, it’s also a prebiotic used to promote the growth of healthy bacteria in a dog’s digestive tract.

Next, the company appears to have applied friendly bacteria to the surface of the kibble after cooking. These special probiotics are used to enhance a dog’s digestive and immune functions.

And lastly, this food also contains chelated minerals, minerals that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better dog foods.

Canidae Single Grain Protein Plus Dog Food
The Bottom Line

Judging by its ingredients alone, Canidae Single Grain Protein Plus looks to be an above-average dry dog food.

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 32%, a fat level of 16% and estimated carbohydrates of about 44%.

And a fat-to-protein ratio of about 50%.

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

Free of any plant-based protein boosters, this looks like the profile of a kibble containing a notable amount of meat.

Bottom line?

Canidae Single Grain Protein Plus is a rice-based dry dog food using a notable amount of poultry and lamb as its main sources of animal protein, thus earning the brand 5 stars.

Enthusiastically recommended.

    Doggie mom – What did you feed your dog previously? Why the change? Did you transition slowly to a new food?

  • doggie mom

    Do not waste your money on this! I gave it to my dogs thinking it was good having 5 stars. They both started it 2 Weeks ago and both have had runny yellow stools daily! They dont like it and vice versa. I switched to another brand today.

    All the processed man-dubbed dog food companies import some of the ingredients in their respective recipes, from overseas. Canidae is now rife in my country being more accessible. It’s accessibility, cheaper manufacturing alternatives, and widespread marketing, make these larger companies, more lucrative. But Canidae owns itself I think, and not Diamond?

    The best way to ensure your dog doesn’t eat foods that contain ingredients from overseas, is that you feed it, food designed for dogs and cats, from your local butcher.

    And remember a raw meaty bone a day, keeps the vet away.


    Same here. When they switched up the ingredients, the quality went downhill significantly!

    Diamond did not buy out Canidae, Canidae just has there food manufactured there, and all ingredients are what Canidae has shipped to the facility, anything Diamond uses in the own food does not go in to Canidae….   Canidae is opening there own manufacturing plant in May of 2012 in Texas, all Canidae food will be Manufactured exclusively by them only….  Links below:

  • cdog

    they were not actually bought out by diamond, they do however have a contract with diamond to use their facilities for manufacturing their food as demand for the food skyrocketed when canidae was first introduced and the companies facilites were not able to keep up with demand.

    I think this website is so helpful and amazing. I will be getting a puppy (blue/fawn pit) soon in the next week or two, I’m so excited!! I went to the pet store and asked about Evo (because that is what the mother eats) and it was suggested to me Canidae Single-Grain Protein Plus. I saw that on the 5 star list for dry food so I’m very pleased. I was told I wouldn’t need a wet food, but my question is what would you suggest for a canned food just to give the dog variety once in awhile so she’s not always eating the same thing and getting bored with it. Should I stick with Canidae for a alternative or try one of the other brands you have listed above. What should I look for? Merrick looks very good but I wasn’t sure if I should go with a stew-type or just like an Evo 95% Beef?? She’s been eating Iams puppy dry and i will be slowly transitioning her to the Canidae, would wet food help that process? I appreciate any help, thank you.

    I had the same experience with Canidae-Years ago they did fine on it, now they do not. My dogs actually do not do well on any Diamond products anymore.

  • Bob K

    JoShuckman  – Most dog foods have multiple suppliers of ingredients to manage costs due to availability.  If you think the US food sources are special, you are kidding yourself and need to Google – food recalls, Rendering plants, eColli, MadCow, salmonella, chicken farms, turkey farms.  the dog food bags are clearly labeled, if you did not read it then its your fault, not Diamonds.    

  • JoShuckman

    Honestly, I don’t trust any Canidae product since they were bought out by Diamond.  I was using their lamb and rice formula before Diamond bought them and my dogs did well on it.  But they changed the formula without notice and my dogs did not tolerate it well at all.   And I just am not comfortable with Diamond importing ingrediants from overseas.
