    This doesn’t mean that Royal Canin is a bad food. Far from it. We also identified a few scenarios in which we feel Royal Canin may be the superior food. You can find out what those situations are in the article below.

    About Royal Canin

    Royal Canin prides itself on doing as much research as possible before making one of their kibbles — and, given how much food they sell, that must mean they’ve done quite a bit of research indeed.

    Royal Canin Started in France

    Royal Canin was founded in 1968 by a French vet named Dr. Jean Cathary. He wanted to make a food that was designed to meet the nutritional needs of dogs, as based on his years of research.

    Royal Canin grew and became a worldwide behemoth, yet they’ve never stopped overseeing every bit of production to ensure that all their foods meet their rigorous standards.

    The Royal Canin Brand is Known for Its Breed-Specific Foods

    Royal Canin makes dozens of different formulas geared towards certain dog breeds, with the intention of offering them the specific nutrition they need.

    However, it’s not clear that any of these Royal Canin formulas are better suited for those breeds than a generic high-quality food.

    Royal Canin is Owned by Mars, Inc.

    While Royal Canin started off as an independent business, it was acquired by Mars, Inc. in 2001. Mars owns Pedigree and many other brands, making it the largest pet care company in the world.

    Despite being acquired by such a massive conglomerate, Royal Canin has maintained its commitment to making high-quality foods.

    They Don’t Always Use the Highest-Quality Ingredients, However

    Despite their science-based reputation (and premium prices), the company often uses inferior ingredients like corn, wheat, and animal by-products.

    This lowers the quality of some of their foods dramatically, while also making them unsuitable for dogs with sensitive dispositions.

    • Places heavy emphasis on research
    • Makes a lot of breed-specific foods
    • Started by a veterinarian
    • Often uses inferior ingredients
    • On the expensive side
    • Breed-specific foods may not be better than others

    About Blue Buffalo

    Blue Buffalo may not be the oldest dog food company around, but they’ve enjoyed explosive growth, quickly becoming one of the top natural brands in the world.

    The Company Only Started in 2003

    Given how ubiquitous their foods have become in pet stores, you might think that Blue Buffalo is one of the oldest and more established brands in the world.

    However, the fact is Blue Buffalo been around for less than two decades. Most of Blue Buffalo’s growth can be chalked up to offering premium foods that don’t use any suspect ingredients — and good timing, of course.

    Real Meat is Always the First Ingredient

    If you look at any Blue Buffalo ingredients list, one thing will remain constant: the first ingredient will be a meat of some kind.

    This starts the food off on a solid foundation of protein, which is excellent for dogs of all ages.

    They Don’t Use Cheap Fillers or Animal By-Products

    Ingredients like corn, soy, and wheat are commonly added to dog kibble to give it a bit of heft without also bulking up the price. However, many dogs have trouble digesting these ingredients.

    Similarly, animal by-products are made of the meat that would otherwise have been thrown away. It’s low-grade and nasty — and cheap, which is why it’s so common.

    Blue Buffalo doesn’t use any of these ingredients. Thus, it’s a good choice for dogs with sensitive dispositions, or for owners that want to be certain they’re feeding their pooch a high-quality food.

    That Doesn’t Mean That All Blue Buffalo Food is Highly Nutritious

    Blue Buffalo recipes can vary wildly in terms of nutrition levels, so always check the label before buying. After all, just because a food doesn’t have any bad stuff inside it doesn’t mean that it’s full of good stuff.


    3 Most Popular Royal Canin Dog Food Recipes

    1. Royal Canin Size Health Nutrition Maxi Adult

    Royal Canin Size Health Nutrition Maxi Adult Dry Dog Food

    This food has a specific target audience: it’s made for large-breed dogs from 15 months to five years of age. With that kind of precision, it must be good, right?

    Not necessarily. The ingredients list starts off rocky, with chicken by-product meal as the first ingredient. While this means the food will have a decent amount of protein (24%), it’s not good protein. That said, it should still be full of glucosamine, and bigger dogs need all of that they can get.

    There is chicken fat and fish oil in it, though, both of which are full of omega fatty acids. There’s a lot of rice in it too, which can help settle upset stomachs.

    Your dog will need all the rice he can get, since it has a ton of problematic foods like wheat and corn in it. These are just empty calories, but they can also cause digestive issues.

    Royal Canin Size Health is not a bad food — that’s too harsh. However, mediocre might be a spot-on assessment.

    • Has a lot of glucosamine
    • Filled with omega fatty acids
    • Rice can settle upset stomachs
    • Made with low-grade meat
    • Filled with potential allergens

    2. Royal Canin Size Health Nutrition Medium Adult

    While the above Royal Canin recipe was targeted at larger dogs, this one is aimed at medium-sized animals. So, what’s the difference?

    Well, this Royal Canin recipe still uses low-grade chicken by-product meal, but it gets moved down a spot on the ingredients list. In its place is brewers rice, which is gentle on stomachs, but it still means that this food is full of carbs.

    The ingredients seemingly alternate between gentle-on-tummies and potentially problematic. The brewers rice is followed by wheat and corn gluten meal, for example, but further down you’ll find oat groats. The result may be as confusing for your dog’s gut as it was for our brains.

    There’s very little fiber in here, either. That’s despite including plain beet pulp and psyllium husk, so we don’t know why they couldn’t beef that number up a bit.

    We can’t quibble with the inclusion of fish oil, though. It’s fantastic for dogs of all sizes.

    This Royal Canin food is similar to the large breed formula above, but we think it’s a tad bit inferior.

    • Uses gentle starches like rice and oats
    • Includes fish oil
    • Filled with problematic ingredients
    • Little fiber
    • Packed with carbs

    3. Royal Canin Size Health Nutrition Large Aging

    Royal Canin Size Health Nutrition Large Aging 8+ Dry Dog Food

    This is another highly specific Royal Canin food, as it’s intended for older, large breed animals.

    We can at least understand the philosophy behind this one, as it has a bit more protein and fat than the other recipes. This can help dogs feel full without packing on extra pounds, as being overweight is terrible for senior pups.

    Still, the protein, fat, and fiber levels are average at best, and the ingredient quality isn’t any better than the other formulas.

    One thing we do like about this dog food is how soft the kibble is. That makes it easier for older dogs to chew, while also making it suitable for animals suffering from periodontal disease.

    This is a very pricey dog food, though, and we can’t really justify the added expense given the overall lack of nutrients. Still, it’s the pick of this particular litter.

    • Has more protein than other formulas
    • Kibble is soft and easy to eat
    • Can help dogs feel full for longer
    • Still uses subpar ingredients
    • Nutrient levels are average at best
    • Very expensive

    3 Most Popular Blue Buffalo Dog Food Recipes

    1. Blue Buffalo Life Protection Formula Large Breed Adult

    Blue Buffalo Life Protection Formula Natural Adult Dry Dog Food

    Given that we examined several large breed Royal Canin formulas, it only seemed fair that we looked at Blue Buffalo’s version, too.

    This isn’t much better in terms of overall nutrition: it only has 22% protein and 12% fat (although at 6%, it does have a good amount of fiber). However, the sources of those nutrients are much better.

    The Blue Buffalo food uses real chicken, chicken meal, and chicken fat — no by-products. Also, you won’t find any cheap fillers, as they instead rely on foods like oatmeal, rice, and peas.

    There are some superfoods in here too, like flaxseed, fish oil, blueberries, cranberries, and kelp. Those are all packed with important vitamins and minerals.

    This Blue Buffalo formula uses a bit more plant protein than we’d like, and the salt levels are high, but we think it represents a clear improvement on Royal Canin’s formula.

    • Uses high-quality ingredients
    • Packed with nutrient-rich superfoods
    • Good amount of fiber
    • Overall protein and fat levels are low
    • Relies heavily on plant protein
    • Too much salt

    2. Blue Buffalo Freedom Grain Free Natural Adult

    Blue Buffalo Freedom Adult Grain-Free Dry Dog Food (Chicken)

    None of Blue Buffalo’s recipes use corn, wheat, or other cheap filler grains, but this one goes one step further by eliminating all forms of gluten. As a result, it’s excellent for dogs with sensitive digestive tracts.

    That’s why we’re so surprised to see potatoes so high on the ingredients list. They’re not a bad ingredient, but they do tend to give a lot of dogs gas, so your pup may have some discomfort with this dog food.

    The overall protein level is average at best, but at least it comes from a wide variety of sources: chicken, chicken meal, turkey meal, and chicken fat. That gives your dog a broad array of essential amino acids.

    Like the above Blue Buffalo food, this one has quite a few superfoods in it, so your dog should get all the vitamins and minerals he needs.

    Ultimately, this is a good Blue Buffalo food, but it’s not one that blows us away. Still, the negatives aren’t worth complaining very loudly about.

    • No gluten whatsoever
    • Broad array of protein sources
    • Filled with superfoods
    • Potatoes can cause gas
    • Mediocre protein levels

    3. Blue Buffalo Wilderness High Protein Grain Free Natural Adult

    Blue Buffalo Wilderness Healthy Weight Grain-Free Dry Dog Food

    This is one of Blue Buffalo’s highest-end foods, as it’s high protein, grain-free, and healthy weight.

    The protein levels are high — 30%, to be exact. The fiber is also very high, at 10%, but the fat levels are mediocre, as they’re also at 10%. Hopefully, the protein should be enough to keep your dog full between meals.

    A lot of that protein comes from plants, though, which doesn’t have the same essential amino acids that animal protein does. It’s still good, just not as good.

    There’s quite a bit of glucosamine in here, due to the chicken meal, so your dog’s joints should be supported while he drops a few pounds. There are a ton of omega fatty acids too, as it has fish meal, flaxseed, and chicken fat.

    This is an excellent dog food for overweight dogs, and one of our favorites overall (the Wilderness line tends to be our favorite from Blue Buffalo).

    • High protein levels
    • Also high in fiber
    • Lots of glucosamine
    • Much of the protein comes from plants
    • Low fat levels

    Recall History of Royal Canin and Blue Buffalo

    While Royal Canin and Blue Buffalo are similar in many ways, their recall histories are drastically different.

    Both companies were involved in the Great Melamine Recall of 2007. This affected over 100 brands, as an incident at a Chinese processing plant caused dog foods to become tainted with melamine, a chemical in plastic that’s lethal to pets. Thousands of animals died from eating bad dog food, but we don’t know if any died from eating Royal Canin or Blue Buffalo specifically.

    Royal Canin also had a recall in 2006 due to elevated vitamin D levels, but they’ve been clean since then.

    Despite only having been around since 2003, Blue Buffalo has been active on the recall circuit. They also suffered a vitamin D-related recall in 2010, and in 2015 they had to bring back bones that were contaminated with Salmonella.

    Their canned dog foods have been especially susceptible to recalls. They were recalled in 2016 due to mold, and twice in 2017 — once for having pieces of metal in the dog food, and another time for having elevated levels of beef thyroid hormone.

    Most troubling of all, though, the FDA has linked them (along with at least 15 other foods) with an increased risk of heart disease in dogs. The evidence is far from clear, but the situation bears monitoring.

    Royal Canin vs. Blue Buffalo Comparison

    In order to give you a better idea of how the two dog foods compare next to one another, we looked at them head-to-head in the following categories:


    Blue Buffalo should be the winner here. They use high-quality meat as their first ingredient, whereas Royal Canin often relies on animal by-product meal.

    Think about it this way: do you think you could tell the difference between a prime cut of steak and a hunk of low-grade meat? So can your dog.

    Nutritional Value

    Likewise, the fact that Blue Buffalo uses such better meat means they have a more nutritional value. The inferior meat that makes up animal by-products is often stripped of many important nutrients.

    Beyond that, Blue Buffalo puts other high-quality ingredients in their dog foods, like kale, cranberries, and more. All of these help it blow Royal Canin out of the water from a nutritional perspective.


    Royal Canin tends to be a little cheaper, but not by as much as you’d expect, given the lower quality of their ingredients.

    However, they do have some specialty dog foods that can be just as expensive as anything Blue Buffalo offers.


    Selection is an area in which few companies can compete with Royal Canin. However, their expansive catalogue may not be as impressive as it first appears.

    One of their calling cards is the fact that they have many dog foods that are specially designed for certain breeds. Upon closer examination, though, many of those dog foods aren’t any better for that breed than any other high-quality dog food would be.

    Still, this category is only about quantity, not quality, so Royal Canin is the clear winner.


    We were looking forward to this matchup, but after digging deeply into both brands, we discovered that Royal Canin is kind of a disappointment, especially given its illustrious reputation.

    It uses lots of low-quality dog foods, and it doesn’t offer much nutritional support. To top it all off, it’s fairly expensive.

    As a result, it was easy to crown Blue Buffalo the champ here.

    This matchup wasn’t as close as we assumed it would be before we started. Blue Buffalo uses better ingredients, has superior nutrition, and is more likely to be tolerated by your dog, making it the easy winner.

    You may be tempted to feed your dog one of Royal Canin’s breed-specific dog foods, and that’s fine if you do your research. However, we’ve largely found that those dog foods aren’t nearly as good as an all-around high-quality food.

    We’re not saying Blue Buffalo is the best dog food in the world (and we definitely have some concerns about their safety history), but given the choice between it and Royal Canin, we’ll take Blue Buffalo every time.
