Meets the nutritional needs of extra-large puppies in their second growth stage (after 8 months)

Supports muscle development with adapted protein levels; is enriched with L-carnitine

Promotes healthy bones and joints through an adapted energy intake and balanced mineral content

Aids developing immune systems and digestive health with an exclusive blend of antioxidants and prebiotics

Your giant puppy is destined for big things—and as they grow, they have big nutritional needs. Giant breed dogs have the longest growth period out of other sized dogs—that’s why Royal Canin growth formulas for giant-sized dogs come in two stages: Giant Puppy and Giant Junior. This Giant Junior dry dog food diet is made specifically for that second stage of growth. At around 8 months, they start to fill out their long and lanky body, developing muscles to support their large frame long into adulthood. What you feed them now sets them up for a healthy, happy life as an adult.

Royal Canin Giant Junior is a nutrient-dense diet formulated for your puppy’s healthy growth: Adapted protein levels and added L-carnitine help build strong muscles. Balanced energy content and precise amounts of calcium and phosphorus support healthy bones and joints. Highly digestible proteins and prebiotics promote healthy digestion and optimal stool quality. Key antioxidants and minerals support developing immune systems to help your dog keep growing strong. Transitioning from Royal Canin Giant Puppy to Giant Junior is easy, because both formulas have an exclusive kibble designed specifically for these growing dogs’ large jaws, so they chew their kibble thoroughly. With the targeted nutrition of Royal Canin, your lovable giant can grow up and live their best, most magnificent life.

Beautiful Coat

My Rottweiler is 13 months old and has been on this line of food since I brought him home. He looks gorgeous compared to his litter mates. He has no digestive issues and he loves the food. I would never feed anything other than Royal Canin to any of my pets.

Keeps my dog healthy

We've been using Royal Canin for 3 years for both our pure breed English Mastiff dogs. I like how the dog food grows with them and meets their needs at the age they are at.

Just Perfect

We have a Great Dane named Pepper. Was using Rayal Canin puppy dry food since her childhood. Now she is 11 months old and for last 3 months is feeding her this product. I must say, this product of Royal Canin is simply the right food I could have opted for her. Maintains perfect weight, shape, coat texture, digestion process and also boosts her immunity system. This product is just perfect!

Absolutely love it!

I have my 9 month old great pyrenees service dog on this diet. He was lanky and the age of 6 months so we transitioned him to Junior Giant, and now he is building muscle!! It was a quick and easy transition from puppy to giant, my pup didnt mind the change at all. And still less stools than the other brand. Definitely a must have for giant breed dogs, absolutely recommend it!

Best Dog Food for your Saint Bernard!

I have tried many brands for my one year old Saint Bernard and I noticed that Royal Canine works the best. Not only was his weight at a healthy size but his fur is very shiny and his skin looked healthy too. I love that how this focuses on the nutrition big dogs need. Would definitely recommend!

Great results

Were started giving our underweight rescue this food the months ago. He's gone from 23lbs to over 60. His coat is beautiful, he's happy and healthy.
