These powerful and devoted dogs can often suffer from digestive sensitivities, joint pain and even cardiac issues. Royal Canin Maxi addresses the needs of the large dog throughout its lifetime - from the large dog’s longer growth period, to nutrients to help limit inflammation of the joints and highly digestible proteins to ease digestion.

This is only a guide. Optimal feeding amounts may vary according to your pet's temperament, activity level and environment. If you have any questions regarding your pet's health, please contact your veterinarian.

Transition Instructions

We recommend at least a 7 day transition before you begin feeding the new food exclusively. Start by mixing 75% of the old diet with 25% of the new diet on Day 1 and Day 2. On Day 3 and Day 4, mix 50% of the old diet with 50% of the new diet. On Day 5 and Day 6, mix 25% of the old diet with 75% of the new diet. On the 7th day, you can feed the new food exclusively. This allows your pet’s digestive system to smoothly adapt to the new food.


How are Royal Canin diets preserved?

All of our dry diets are preserved naturally with mixed tocopherols, citric acid, and rosemary extract. Our canned diets are naturally preserved and sterilized during the cooking and canning process.

Where do the ingredients in Royal Canin diets come from?

We select our ingredients based on multiple factors, including the supplier’s compliance with our quality and food safety requirements, consistent availability, and on the nutrients required to meet the dietary needs of the pet.Royal Canin is making strides towards sustainability by attempting to obtain sources of raw materials as close to each manufacturing facility as possible. In some cases, we use international suppliers, because only those suppliers can offer raw materials that comply with our quality and food safety standards.

Why do some Royal Canin diets contain by-products?

Royal Canin chooses ingredients because they deliver high-quality nutrients that support our customized pet food formulas. Using chicken by-product meal instead of chicken meal for example will allow Royal Canin to maintain its highly customized nutrient standards while achieving a more secure and sustainable supply.

Why do some Royal Canin diets contain grains?

Grains can be a healthy part of any cat or dog’s diet. As always, we focus on the nutrients each ingredient provides and grains can provide many important nutrients.

How do you ensure Royal Canin diets are safe for my pet?

Our Quality and Food Safety systems are state-of-the-art and we continue to invest heavily in new technology to make sure they remain that way.* We put our suppliers through a rigorous selection process that doesn’t end with our first purchase.* We monitor every load delivered to our plants to verify the safety and quality of the ingredients we use to make pet food.* We perform tests on finished pet foods before they are shipped to our customers.* We manufacture every pet food we sell, in plants that we own; our plants are ISO 9001:2008 certified for Quality Management and ISO 22000 certified for Food Safety.

  • Great food; bad packaging

    By on

    The Royal Canin 8+ Maxi dry dog food has helped our 11-year-old black lab. She has always had a sensitive digestive system. Since being on this food she has had no symptoms, and has not turned her nose up to it, as she has eventually with other foods. My only complaint is the packaging. I love that it is a resealable bag, but the zip closure on this 30-pound bag of dog food is sufficient for a snack baggie. Royal Canin, thank you for this food; please consider looking into a better closure for the bag.

  • German Shepard

    Luka loves this food! He used to eat RC German Shepard. He was never crazy about it, but reluctantly ate it. Now that he’s older, I am giving this a try. So far he loves it!

  • Big Kibble for Senior Dog

    By on

    This food was recommended by my vet for my senior dog so I tried it. I was surprised at how big the kibble was. Seemed strange to have that size kibble for a senior dog with aging teeth. Had to put water on it to soften for my dog, but she seemed to like it once it was softened up.

  • Great product

    By on

    I can't say enough good things about this dog food. Both my senior dogs - an 11-year-old Rottie and a 15-year-old lab mix - were having some pretty serious digestive issues. I took my lab mix to the vet who suggested I change the food I was feeding him. My sister uses Royal Canin for her boxer and recommended that I try the brand. Both my dogs LOVE it. The digestive issues have all cleared up and their coats look better and both dogs seem to be feeling so much better. I will never use another brand for these dogs or any other dogs I may have in the future.

  • Ava loves this dog food

    By on

    My GS dog absolutely loves this Royal Canin Maxi Aging 8+ brand dog food. Sounds a little crazy but I think she even looks happier since we’ve started feeding her RC.
