About Royal Canin Giant Puppy

Designed for Giant Puppies

Your giant puppy can benefit from a diet that supports healthy weight and muscle development to keep his body growing strong. That’s why Royal Canin Giant Puppy and Giant Junior dog foods are tailor-made for the healthy growth and development of very large dog breeds—specifically, those that will have an adult weight of over 100 pounds.

Give Your Puppy a Perfect Start

Giant Puppy and Giant Junior dog food formulas are crafted with complete and balanced nutrition to help build and maintain the body as it grows.

Brain Development

Formulated with DHA, an omega-3 fatty acid, to support healthy brain development in puppies.

Strong Immunity

Antioxidants, including vitamins E and C, help support immune system development.

Microbiome Support

Prebiotics and highly digestible proteins help promote a balance of intestinal bacteria for a healthy digestive system.

Specialized Kibble

Tailored kibble size and wet food with a savory aroma and adapted texture are made for growing giant-breed puppies.

Choosing the Right Diet

Giant-breed dogs have the longest growth period of all breed sizes. That’s why Royal Canin growth formulas for giant dogs come in two stages.

Puppy Stage: Intense Growth

Your giant puppy has unique nutritional needs during the period of intense growth from 2 to 8 months. Royal Canin Giant Puppy supports these needs with clinically proven antioxidants and a combination of prebiotics and highly digestible proteins. It also helps your puppy avoid excess weight gain.

Junior Stage: Muscle Development

As your giant puppy gains muscle during the final growth stage, the adapted protein content of Royal Canin Giant Junior helps support muscle development from 8 to 18-24 months of age. Proper nutrition is critical to maintaining the steady growth that leads to a healthy adult dog.

Mix It Up With Dry and Wet Food

Give your puppy a complete feeding routine. Wet meals provide appetite-stimulating aromas, soft texture for baby teeth, and more water in the diet. Kibble meals contain a concentrated source of nutrients, with an adapted kibble size and shape tailored to your puppy’s jaw size. With mixed feeding, your puppy will be exposed to different varieties of textures of food, helping him become more accepting of dry and wet food as he approaches adulthood.

Questions & Answers

9 Customer Questions


My Dane is 10 mos 86# & still eating 6-7 Cups of Royal Canin Giant puppy food a day should I change her to junior yet?

Answer by ChewyFeb 28, 2021
This recipe is formulated for puppies up to 8 months over 100 pounds. After this they should be transitioned to Royal Canin Giant Junior Dry Dog Food which is for puppies from 8 to 18/24 months old and over 100 pounds. We recommend at least a 7 day transition before you begin feeding the new food exclusively.

How many cups of food are in a 30-lb. bag?

Answer by ChewyMay 14, 2019
The 6 pounds bag contains approximately 24 cups of food, and the 30 pound bag contains approximately 120 cups of food.

I have a 4 month old puppy that’s almost 50lbs. The suggested feeding chart is alittle confusing, could you explain or clarify how to read the feeding chart. Thanks!

Answer by ChewyMay 09, 2019
it's recommended to pick your dog's adult target weight found in the first column. Then increase the feeding amount each month based on your dog's age.

When do I start with royal canin junior for my giant breed puppy. I feed her three times a day with giant breed puppy. She is six months old but almost seven months. Do I continue three times a day with the junior feed.

Answer by ChewyNov 16, 2020
Royal Canin Giant Junior Dry Dog Food is suitable for puppies from 8 to 18/24 months old and over 100 pounds. The attached feeding guide is a general recommendation for daily feeding amounts for a pets optimal weight. This may be adjusted for each individual pets nutritional needs. If you have any questions regarding your pet's health, please contact your veterinarian.

Kibble for Giant Dog

I did not know that there was a bigger than large dog food. I am so happy to find something specific for my baby. He likes it better than the old dog food.

A food that didn’t aggravate skin conditions.

Royal Canin eased our dog’s itching/scratching. His hair looks better and he loves the taste. Highly recommend this puppy food for giant breeds.

The only puppy food I would ever feed a giant breed dog!

my pup wasn’t crazy about the taste and it broke her out in welts. I changed her over to Purina Pro Plan per my breeder and shes fine now. The thing about large breeds is they often suffer from food allergies.

My pup loves the food, but I am afraid it might give him diarrhea. He's a Bernedoodle and a lot of the food has given him diarrhea and we're trying this out. So far it's been a week and his stools seem a little softer. Fingers crossed that everything is okay.
