    About Royal Canin

    Royal Canin has been around since 1968 and was originally founded in France. It was created by a dog owner and vet, Jean Cathary, who noticed that his dog had several skin-related issues that were ultimately due to its poor diet. From there, the Royal Canin brand was founded and has become one of the most recognizable pet food brands in Europe and the United States.

    The company is now a part of the Mars Inc. brand and has grown tremendously since its inception. One of the biggest advantages of their pet food is its nutritional content and its ability to provide safe food options for dogs and cats that have dietary restrictions. The brand works directly with nutritionists and licensed veterinarians to help provide direct guidance on creating new meal formulas.

    They’re based in St. Charles, Missouri and you’ll regularly see their products available online on sites by Chewy, Amazon, and Walmart, and you also find them in most pet stores. The manufacturing plant is in South Dakota and the five main ingredients in most of their meals include some type of protein, rice, wheat, or another grain.

    Royal Canin also has an impressive list of meals available for young puppies that may not be ready to eat adult food quite yet. They have both wet and dry food and meals designated for specific breeds. Royal Canin is considered a premium dog food brand and they have a large share of the marketplace in terms of annual dog and cat food sales.

    • Offers nutritional meals for dietary restrictions
    • Has breed-specific meal options
    • Includes formulas for young puppies
    • Uses high-quality ingredients

    Canin Royal and Purina Pro Plan Comparison


    Unfortunately, dogs can’t talk to us and tell us just how good their food is. However, judging by the reviews of both brands, it seems that they each have meals that are more favored than others.

    The wet meals containing fish and the dry food meals containing chicken seem to be the most popular choices, for Canine Royal, the dry chicken meals seem to sell out the most. And for Purina Pro Plan, the dry food containing salmon and rice seems to be one of the biggest sellers.

    Nutritional Value

    When comparing nutritional value, Royal Canin, like many canine foods, contains protein and fat as the main ingredients, hovering at about 26% in each meal. In terms of fat, many products contain anywhere from 1-2%. Most of the wet food products have about 81% moisture, which is normal.

    The Purina Pro meals have about the same amount of protein, hovering at around 26% for the dry meals and about 9% for the wet meals. Each brand has a line of digestive-centered foods that contain probiotics and, in some cases, prebiotic fiber to assist with immune health.

    Other than that, you’ll find subtle differences in the food plans based on the type of diet or breed that they cater to. However, you’ll ultimately find that Royal Canin has more dry food options available.


    So, this is where Purina Pro takes the lead. On average, it tends to be about 10-15% cheaper than the Royal Canin brand and both wet and dry food options. This can mean a lot if you’re on a budget, and it’s worth noting as both brands have similarities in nutritional content and food availability.

    The Royal Canin brand has more dry meal options and a few more wet food options available. So, if you have a dog that has specific diet restrictions, it may have more foods to cater to its needs. So, they’re winning in this category.


    We find that both brands have a good number of quality meal options available for both dry and wet foods. Also, they’re both great options to consider if you have a dog that has food sensitivities, allergies, digestive issues, or any other health problems. However, the difference in price may be enough to sway you, especially if you find a Purina Pro Plan that can work for your dog’s health specifically.

    We’ve found that The Purina Pro Plan takes home the trophy in this dog food review. They may not have as many products as Royal Canin, but it’s more affordable. They also have a sufficient number of options to make you reconsider if Royal Canin is your number one pick.

    Lastly, Purina Pro Plan has recipes for senior dogs, puppies, dogs with digestive issues, and those with weight problems. Chances are, if your dog is suffering from health issues, they may offer an affordable meal plan to cater to its needs
