Dry Matter Basis32%16%44%

Protein = 28% | Fat = 33% | Carbs = 39%

The first ingredient in this dog food is brewers rice. Brewers rice is a cereal grain by-product consisting of the small fragments left over after milling whole rice. Aside from the caloric energy it contains, this item is of only modest nutritional value to a dog.

The second ingredient is chicken by-product meal, a dry rendered product of slaughterhouse waste. It’s made from what’s left of a slaughtered chicken after all the prime cuts have been removed.

In addition to organs (the nourishing part), this stuff can contain almost anything — feet, beaks, undeveloped eggs — anything except feathers.

On the brighter side, by-product meals are meat concentrates and contain nearly 300% more protein than fresh chicken.

In any case, although this item contains all the amino acids a dog needs, we consider chicken by-products an inexpensive, lower quality ingredient.

The third ingredient is corn. Corn is an inexpensive and controversial cereal grain. And aside from its energy content, this grain is of only modest nutritional value to a dog.

For this reason, we do not consider corn a preferred component in any dog food.

The fourth ingredient is wheat gluten. Gluten is the rubbery residue remaining once wheat has had most of its starchy carbohydrate washed out of it.

Although wheat gluten contains 80% protein, this ingredient would be expected to have a lower biological value than meat.

The fifth ingredient is corn gluten meal. Gluten is the rubbery residue remaining once corn has had most of its starchy carbohydrate washed out of it.

Although corn gluten meal contains 60% protein, this ingredient would be expected to have a lower biological value than meat.

And less costly plant-based products like wheat gluten and corn gluten meal can notably boost the total protein reported on the label — factors that must be considered when judging the actual meat content of this dog food.

The sixth 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.

After the natural flavor, we find beet pulp. Beet pulp is a controversial ingredient, 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.

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 four notable exceptions

First, vegetable oil is a generic oil of unknown origin. The ratio of omega-6 to omega-3 fats in any oil is nutritionally critical and can vary significantly (depending on the source).

Without knowing more, it’s impossible to judge the quality of an item so vaguely described. However, compared to a named animal fat, a generic vegetable oil cannot be considered a quality ingredient.

Next, we find grain distillers dried yeast, a by-product resulting from the fermentation of grains separated from distilling mash as a by-product of the production of ethanol (biofuel).

Even though it contains over 40% protein, this ingredient would be expected to have a lower biological value than meat.

And less costly plant-based products like this can notably boost the total protein reported on the label — a factor that must be considered when judging the meat content of this dog food.

In addition, this recipe contains fructooligosaccharide, an alternative sweetener1 probably used here as a prebiotic. Prebiotics function to support the growth of healthy bacteria in the large intestine.

And lastly, this food includes 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.

Royal Canin Giant Dog Food
The Bottom Line

Judging by its ingredients alone, Royal Canin Giant Dog Food looks like a below-average dry 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 32%, a fat level of 16% and estimated carbohydrates of about 44%.

As a group, the brand features an average protein content of 32% and a mean fat level of 16%. Together, these figures suggest a carbohydrate content of 44% for the overall product line.

And a fat-to-protein ratio of about 51%.

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

When you consider the protein-boosting effect of the wheat gluten, corn gluten meal and grain distillers dried yeast, this looks like the profile of a dry product containing just a moderate amount of meat.

Bottom line?

Royal Canin Giant is a plant-based dry dog food using a moderate amount of chicken by-product meal as its main sources of animal protein, thus earning the brand 3 stars.


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.

    I was very happy to find this web-site.I wanted to thank you for your time in creating such a wonderful read!! I really appreciate every bit and I’ll check your new blog posts. I work at and get quite allot of people asking my opinion on the different dog food, I’ll be sure to recommend this article to our clients.

  • Jason

    Thank you for your replies, I once again confused that our eukanuba (even though it seems imported) is different to yours, apart from its inclusion of dried turkey its pretty much the same as our RC I ahve bought my pup both and compared both packets side by side and found them to be similar…. I agree that they are in no way a super premium dog food but a great mid range compromise… was just wondering why eukanuba is getting these outstanding results .. Thanks for the replies TheBcnut especially, a reply is better than some automated cut and paste job and it is appreciated (thumbs up)

  • theBCnut

    Sorry, I didn’t have time to elaborate earier, but on this site anonymous ingredients are a negative, so dehydrated poultry protein, animal fats, and hydrolysed animal proteins, with no clue what animal(s) they came from, may cause the rating to be lowered. Also plant proteins used to boost the protein content are a negative, so vegetable protein isolate may lower the star rating. These are some of the criteria Dr Mike uses when evaluating foods, based on what he believes makes the healthiest diet for an animal that was made to eat primarily meat. Not to say it is true of this food in particular, but when a food lists anonymous ingredients, it can be from very bad sources, like euthanized animals or diseased animals, so since we don’t know batch to batch where any dog food manufacturer gets or will get their anonymous meats, it is assumed it can be very poor quality and that affects the ratings.

  • Storm’s Mom

    Here’s the ingredient lists for both your RC formula and the Eukanuba Large Breed. I’m not seeing how yours is anywhere near “pretty much the same” as the Eukanuba (not that I’m a fan of either one).

    Your RC formula:

    dehydrated poultry protein, rice, maize, animal fats, vegetable protein isolate*, hydrolysed animal proteins, beet pulp, minerals, fish oil, soya oil, yeasts, psyllium husks and seeds, fructo-oligo-saccharides, hydrolysed yeast (source of manno oligosaccharides), hydrolysed crustaceans (source of glucosamine), marigold extract (source of lutein), hydrolysed cartilage (source of chondroitin).

    Eukanuba Large Breed:

    Chicken, Corn Meal, Ground Whole Grain Sorghum, Chicken By-Product Meal (Natural source of Chondroitin Sulfate and Glucosamine), Ground Whole Grain Barley, Dried Beet Pulp, Chicken Flavor, Chicken Fat (preserved with mixed Tocopherols, a source of Vitamin E), Dried Egg Product, Potassium Chloride, Fish Oil (preserved with mixed Tocopherols, a source of Vitamin E), Salt, Sodium Hexametaphosphate, Flax Meal, Fructooligosaccharides, Calcium Carbonate, Choline Chloride, Minerals (Ferrous Sulfate, Zinc Oxide, Manganese Sulfate, Copper Sulfate, Manganous Oxide, Potassium Iodide, Cobalt Carbonate), DL-Methionine, Vitamins (Ascorbic Acid, Vitamin A Acetate, Calcium Pantothenate, Biotin, Thiamine Mononitrate (source of vitamin B1), Vitamin B12 Supplement, Niacin, Riboflavin Supplement (source of vitamin B2), Inositol, Pyridoxine Hydrochloride (source of vitamin B6), Vitamin D3 Supplement, Folic Acid), Vitamin E Supplement, Brewers Dried Yeast, Beta-Carotene, Rosemary Extract

    Both have “beet pulp” and “fish oil”, but that’s about all they have in common. There’s no way your RC formula would rate 4 stars…although, admittedly, I’m not sure I’d rate Eukanuba LB as 4 stars like Mike had done, either, but that’s just me. Your RC formula rated as 2.5 stars does seems about right, imho.

    Dont worry, our Royal Canin here in SA has different, better ingredients that the one listed on this site. According to this site i would rate ours at 3.5 or the same as the eukanuba large puppy at 4 stars…. My little boerboel was on eukanuba and we just switched to royal canin because he diddnt enjoy it, never looked back and as far as I can tell he is one extremely happy chappy. (not bashing eukanuba he was in great condition on it he just preffered the taste)

  • Jason

    Not from US but that’s pretty much the same at the eukanuba large breed which is 4 stars, so your statement of “even with that list it wouldn’t fair much better” is one which has no ground to stand on… Thanks for the info though never knew they varied.. obviously now that I think about it it comes down to local supply etc….

  • theBCnut

    Are you, by chance, not from the US, because that does not sound like a US label. The ingedients are different depending on where it was produced for. And even with that ingredient list, it still wouldn’t fare much better here. Also, this review was last update September of 2013, not 3 years ago, and it will be updated again in March of 2015.

  • Jason

    Strange…ingredients on mine list dehydrated poultry as main ingredient .. no meals nd stuff… think this review needs an update…

    COMPOSITION: dehydrated poultry protein, rice, maize, animal fats, vegetable protein isolate*, hydrolysed animal proteins, beet pulp, minerals, fish oil, soya oil, yeasts, psyllium husks and seeds, fructo-oligo-saccharides, hydrolysed yeast (source of manno oligosaccharides), hydrolysed crustaceans (source of glucosamine), marigold extract (source of lutein), hydrolysed cartilage (source of chondroitin). ADDITIVES (per kg): Nutritional additives: Vitamin A: 17100 IU, Vitamin D3: 1100 IU, E1 (Iron): 52 mg, E2 (Iodine): 5.2 mg, E4 (Copper): 9 mg, E5 (Manganese): 68 mg, E6 (Zinc): 203 mg, E8 (Selenium): 0.1 mg, L-carnitine: 300 mg – Preservatives – Antioxidants. ANALYTICAL CONSTITUENTS: Protein: 31% – Fat content: 16% – Crude ash: 8% – Crude fibres:1.3% – Per kg: Calcium: 12 g – Phosphorus: 9.5 g – Fructo-oligo-saccharides: 3.4 g – Manno-oligo-saccharides: 0.5 g. *L.I.P.: protein selected for its very high assimilation.

    According to your “guidelines” this dog food is sorely underrated at 2.5 stars… Id appreciate it if such a valued and trusted site would keep their reviews up to date as it is a simple and necessary thing to do. People are looking for answers in the NOW not if they buy 3 year old dog food come now…

  • theBCnut

    I posted a reply directly to her too.

  • LabsRawesome

    Hey Patty, yes, it can get confusing. That’s why I try to write the whole name of the product out, for other readers, so everyone is on the same page. When I decided to try GF 4health cat, I checked and it is made by Ainsworth. I don’t use the grain inclusive one that’s made by Diamond. I wish the whole 4health line was made by Ainsworth. It would be a lot less confusing for everyone. I hope Cayce sees our posts, and she doesn’t throw her food out. 🙂

  • theBCnut

    OT, but I can’t seem to post to the Victor thread were the convo is at, also OT. The grain free 4Health cat food is definitely made at Ainsworth at this time, I just lost tract of which one they were talking about because they started referring to it as just 4Health in several posts. My brain is somewhat like spaghetti, I guess.

  • LabsRawesome

    Yes they are. I’ve looked at the different formulas/breeds and they are all the same ingredients. Royal Canin is all just marketing. You’re dog may do fantastic on it, but it’s still just marketing, to make people think their getting something special for their particular breed.

  • Crazy4cats

    Yes, I have vacuum eating lab mixes!

  • David Tudor

    ha ha ha that’s funny. I really get that.
    My meaning of the kibble size and shape actually has scientific basis in that some shapes are easier to pick up with a bracheasyphilic jaw structure or little teeth or even the labrador who tends to vacuum feed. It’s a real issue for some dogs and cats. Just my humble opinion, and a little science.

  • Crazy4cats

    I don’t think the kibble hits my dogs’ mouth long enough for them to notice a size or shape!

  • David Tudor

    Yes, I was there from 2012 till 2013, March

  • David Tudor

    I apologize. It will not happen again. I do appreciate the forum and comments.

  • Feel free to post your experiences and opinions on this website.

    So, please limit each of your comments to one single occurrence. Thanks.

  • Betsy Greer

    So, you were employed by Royal Canin as recently as October of 2013?

  • David Tudor

    Just a quick note, the ingredient lists may look similar but they are not, I assure you. As well, Kibble shape and size make a difference with different dogs mouths. While it may have a lot to do with marketing, I am very comfortable in stating that RC truly puts the pets first. I have many stories and different perspectives to offer, but will refrain.
    Royal Canin has served me and all of my friends very well, if and when money becomes an issue, I may look elsewhere. But since my dog is only 7 pounds, it isn’t likely. She doesn’t eat much.
    Just remember, not everything on the internet is truth. Bon Jour.

  • LabsRawesome

    It’s great that it works for your dog. But it is all a marketing ploy. People like to feel special. Don’t believe me? Compare the ingredient list on lets say Dachshund with the ingredient list for Boxer. Or any of the ingredient lists, they are all the same!! They may have a slight variation of order of ingredients, but are all basically the same exact food. With very low grade ingredients. You could do much better than Royal Canin, and probably even pay less $.

  • David Tudor

    I just (very) recently left RC to move to another State, Ohio. I was what they call a “nutritional advisor”. My 12 years as a Human nutrition and medical experience meant nothing to my job relating to Dogs and Cats. I realize my background was beneficial yet highly useless when relating to an omnivore (dog) and carnivore (cat) diets of animals.

    I am amazed daily by the ignorance of Humans who believe their pet must be exactly like them: “I’m a vegetarian, so my dog must be vegan.” I don’t LIKE corn, so my dog is allergic to corn.”

    Seriously, I know for a FACT that the breed specific RC diets are studied, tested and researched for over two years with 100% success before release. If they fail by 1-2% after the study, they start over. PERIOD.

    The more generalized Size and group specific diets are equally scrutinized.

    I am proud to tell you that my Maltese had her 1 1/2 year check up. He told me: “in 23 years, I have never seen a more perfect specimen of a Maltese. This is Best of Show Material. Perfect Heart, bones, eyes, coat…

    My goodness what are you feeding her?”

    I told him she has only had Royal Canin, and no table food.

    “That must be it,” he said.

    I corrected, “Actually, she has never had tap water, only filtered; NOT distilled. Plus daily exercise and grooming with lots of love.”

    So, in my humble opinion, MY DOG does great on the food. She eats the Mini Adult, (With the Pappillion on the bag) and loves it. As a realist, I know that dogs are all different and have different needs. The breed specific is great for most of its specified breed, but nothing is perfect for the 90 million different dogs. I am sad to read the “internet bullies” comments, but hope you get some insight from someone on the inside.

    It works for me, and I know many people who swear by it. I also know some who don’t know what they are talking about who are put in positions to criticize without merit. Just my opinion.

  • Courtenay

    I was recommended your site by our the chat assistant on and I must say its really really impressive.

    The review of the above food really makes one feel they know exactly what they’re getting for their dog. Our great dane has been eating Royal Canin for a long time, this product especially so it makes sense for him to continue on it, even though it didn’t get the best reviews. Hoping that will get to stock some of the more well reviewed dog foods on your site…

    Thanks again for an informative site. Definitely will recommend to others


  • sara

    Hi I try to call tham on that number, but it is not working from here. I am living in australia QLD in Cairns.

  • Hi Sara… Are you outside of the United States? If so, you should be aware that manufacturers frequently use different ingredients for many of their products. My best recommendation… check with Royal Canin. Send them an email or give them a call.

  • sara

    Thanks a lot it helps. I ordered Royal Canin one month ago from internet and I just now check date and there is best before 18.11.2010 it means they are selling older version of that dry food, it is same think with mini Royal Canin. Sara

  • Hi Sara… I contacted Royal Canin and (also re-checked the company’s website). I’ve confirmed our published data is correct and up-to-date. If you see those preservatives listed on your package, it’s possible you’re using an older (out-of-date) version of the product. By the way, feeding expired products can be hazardous to your pets. So, be sure to verify the dates on the packages.

    Royal Canin has upgraded and improved many of their recipes. If you have any concerns, I’d suggest you contact the company on their customer service phone number at (800) 592-6687.

    Hope this helps.

  • sara

    Hello again, I just check ingredients on same dry food Royal Canin Giant and I have written there Propyl Gallate, Butilated hydroxyanisole (BHA), but I can not see them here in your ingredients. Same for Mini Royal Canin for Jack Russel? Thanks Sara
