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.

How do I know which Royal Canin diet is right for my pet?

Based on size, age, lifestyle, and breed, each cat or dog has unique nutritional needs. For healthy pets, use our Product Selector to find the right diet for your cat or dog.If your pet is experiencing health issues, please refer to your veterinarian for more information. Your veterinarian will consider multiple factors when recommending an appropriate diet.

  • My dog loves this!

    By on

    My dog will eat this dry and that’s saying something as she can get a bit picky from time to time. She seems satisfied after mealtime and she has lost weight. Definitely going to keep her on RC.

  • The right food and plus the Great service.

    By on

    Finally I found the right food by Royal Canin and the best service by Chewy. A combination of the two made my 10 yrs old Australian Blue Healer very happy. Chewy will have Cassie for a customer for a long time.

  • Only Food We Use!

    By on

    This was the dog food recommended for our 8 year old basset hound rescue with liver problems. It is worth every penny knowing that he is getting the best food and we save so much money getting it from Chewy!

    My rescued Jasper has a history of sensitive stomach. It has taken me 4 years to finally find a kibble that agrees with him and he LOVES it.

    While my dog ate his previous type of dog food, I can tell he likes the taste of this one more based on the hoover effect. He's happy!

  • Yum for the tum!

    By on

    My wheaten terrier loves this food. He has always eaten RC Med., but lately had been having gas so since he turned 7 thought we'd give this a try. He loves it and we've noticed much less gas! Fast shipping!

  • Our five (5) dogs/pups love the Canin Dry Dog Food. James G. Boyd.

    By on

    We have five (5) pups, all of whom love the Chewy Canin Dry Dog Food. We used to have ten (ten) pups but my wife and I, both almost 73, have outlived all but five dogs. We have a large kennel with very wide runs at our horse farm, and have a number of "rescued dogs" there. James (Jim). We have also used the canned Canin Dog food for some of the older dogs/pups and they love that product too.
