The first ingredient in this dog food 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 second 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 third ingredient 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 fourth ingredient is wheat. Like corn, wheat is an inexpensive and controversial cereal grain of only modest nutritional value to a dog.

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

The fifth ingredient includes oat groats, a whole grain, minimally processed form of oats. With the exception of their caloric content and the fact they’re also gluten free, oat groats can be considered average in nutritional value.

The sixth 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 this can notably boost the total protein reported on the label — a factor that must be considered when judging the actual meat content of this dog food.

The seventh 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 flavors, we find 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.

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 actual meat content of this dog food.

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 five notable exceptions

First, 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.

Next, grain distillers dried yeast is 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, we note the use of vegetable oil, 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, 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 Maxi Dog Food
The Bottom Line

Judging by its ingredients alone, Royal Canin Maxi 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 27%, a fat level of 17% and estimated carbohydrates of about 49%.

As a group, the brand features an average protein content of 29% and a mean fat level of 16%. Together, these figures suggest a carbohydrate content of 48% for the overall product line.

And a fat-to-protein ratio of about 56%.

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

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

Bottom line?

Royal Canin Maxi is a plant-based dry dog food using a moderate amount of chicken by-product meal as its main source 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 think that should be like a new thing, it would be amazing, heck i’d do it if I knew anything about website design, sadly I don’t know s**t haha.

  • Veronika

    I hate them with a passion, received like two of their treat bags the low calorie ones with my usual order for Rusty what junk, no meat high carbs made with wheat and tapioca and yeah only fit for the trash.

    Their food prices are also crazy, one cat food labelled “fit” was $178 for 14kg, man that is just laughable, what about the food is worth $178 based on the ingredients list not a bloody thing, they simply can because no one can stand up to them.
    Hills also had an epic fail pricing on one of their digestive foods, $126 for no meat at all and the bag was 6.8kg >.> nuff said.

  • haleycookie

    I totally agree. But the foods not really rated on how evil the company is

  • Linda Luette Turpin Messersmit

    Royal Canin is a vile company built on greed and avarice… products are near filth and a shame to the dog food industry–almost as horrible as using euthanized dogs and cats made into meat meal….this company takes advantage of ignorance as do far too many others.

  • haleycookie

    Looks like this hasn’t been updated in a year or so. So maybe there was a formula change last year.

  • Linda Luette Turpin Messersmit

    it used to be 2….and still should be

  • haleycookie

    3 stars isn’t very good. Mediocre at best and no they didn’t pay him. These are unbiased reviews based mainly on the ingredient list and guaranteed analysis panel. If you’d like to know more you can search “how we rate dog food” in the search area at the top of the page.

  • Linda Luette Turpin Messersmit

    3 stars…..did they pay you? what garbage

  • Betsy Greer

    I think it’s just you Meghan.

  • Guest

    is it just me or does everyone on this site think they’re a nutritionist? its funny that majority are “holistic – grain free” loving and no one cares for the vet prescribed food. and when you search the vet food they barely have any listed! just seems weird and not right. I mean, I’ll trust my vet who has 25 years of experience over an internet nobody anyday…..just a thought.

  • skylarnz

    Hi was wondering the same as the RC here has the same dehydrated protein. What does that mean? Has anyone got any ideas? Thanks

  • LP

    It’s indeed a very bad food and I know it’s hard to believe but Royal Canin manages to make it MUCH worse!! The first 8 ingredients in the english version of the same Royal Canin Maxi Adult are the following: maize, dehydrated poultry protein, maize flour, animal fats, dehydrated pork protein, hydrolysed animal proteins, beet pulp, maize gluten. Maize as 1st, 3rd and 8th, gluten boosting the (still very low) protein level, generic “animal fat”, generic “poultry”… Scary! But I am only writing to ask Mike (or anyone who knows), what does poultry and pork “protein” exactly mean?? Can it be something worse than by-product? Or is it exactly the same with another name? (

  • Andrew

    When I got my German Shepherd, Sammi, at 9 month, her previous owners had been feeding her this. She pooped at least 4 or 5 times daily (never very solid). They had brought about 25 lbs of it over with her. My brother works at a natural pet food store, and I immediately began to switch her to NutriSource Heartland Select, which was what he suggested. With the Royal Canin, she would not eat immediately when I fed her, she would just graze a little here and there. Once I started switching to the NutriSource, she would flip out every time it was feeding time, and gobble it all down immediately. She started pooping solid twice a day, each about 6 hours after feeding. The NutriSource is less expensive than this crap, and much better in my opinion (and in Sammi’s opinion). I would not recommend this food to anyone. There are better options out there for much less money. The extra 25 lbs got thrown in the garbage, and not even the squirrels bothered with it.

  • Hound Dog Mom

    Hi MountainDaddy –

    There are definitely better foods out there than RC…much better. RC is a premium-priced, average quality food. Basically you’re paying a 5 star price for a 3 star food. I’d recommend checking out the 4 and 5 star foods on this site and find one that fits your budget and that’s available to you.

  • BryanV21

    Well, to be brutally honest, it’s only up from here. Royal Canin is perhaps the last food I’d feed to my dog. Not only are the ingredients poor, but it’s way overpriced as well. Seems like the only people that feed this got bad information on it from their vet or breeder, which is too bad because how would you know any better.

    At that age you should have already moved away from a puppy food. Other than that, without knowing the breed and whether there are any issues with certain ingredients, it’s hard to say other than to look at the 5 star foods here and see what’s available to you.

  • MountainDaddy

    This brand was suggested by our breeder since the first day we brought home our puppy. He likes it plenty, but I too am concerned that this might not be the best food for my dog (now 2yrs old). Can someone recommend a better substitute?

  • Moscalej

    i just to give regal puppies but dive gases to mi dog and the hairdresser told me that his hair was dray (airdale terrier) 

  • BryanV21

    If the first ingredient is not a named animal, then I wouldn’t even consider that food. Seeing that rice is the first ingredient, on top of the fact that the second ingredient doesn’t even name what type of poultry it is, I’d return it. Don’t go for generically named ingredients like “animal” something, like how it later says “animal fats”.

    All of this is assuming you have something in the meantime to feed your dog. Something is better than nothing.

  • Maryjo_g_1975

    I love the Royal Canin foods. I feed both of my Boxers the Royal Canin and they do great with it. I also love the line for cats. My cat was a picky ktten, rescued only weeks old from a drain. He wouldn’t eat anything but I tried the baby cat formula and he ate it! Working at an Animal Hospital, whenever we have kittens who wont eat, we give the baby cat to them. We nicknamed it kitten crack! LOL Bottom line, Royal Canin is good for my animals and they love it! They never miss their meals!
