Growing dogs have developing digestive systems which are prone to digestive issues including loose stool. GIANT Junior helps support improved digestive health through prebiotics (MOS and FOS*) and an optimal fibre balance to help promote a healthy beneficial gut microflora population. Low Indigestible Proteins (LIPs) also help contribute to an optimal stool quality.

The growth phase of giant breed puppies lasts for up to two years, and it is critical that they receive the nutrients they require in the appropriate amounts to ensure optimal development. GIANT Junior promotes the development of strong muscles and sturdy joints through adapted protein levels, glucosamine, chondroitin, L-carnitine, and other key nutrients.

Giant breed dogs put extreme stress on sensitive joints, making them more prone to inflammation and arthritis. GIANT Junior promotes healthy skeletal development in giant breed puppies, with an adapted calcium and phosphorus content, and the addition of glucosamine and chondroitin, along with anti-inflammatory omega 3 fatty acids, EPA and DHA help joints grow strong, to help protect fragile joints and limit inflammation.

During the critical growth phase, the puppy’s immune system is vulnerable. GIANT Junior is formulated with a specialized complex of antioxidants, including vitamins C and E, lutein and taurine, which help to neutralize free radicals and support the development of the puppy’s immune defenses., *Mannanoligosaccharides and Fructooligosaccharides

Dogs are bizarrely wild for this food!!

I can’t claim anything for outcomes yet; however, my two dogs fought over the this kibble. The littler one just devoured the kibble like he’d been starving for his whole life. I think that’s noteworthy given that the dogs share bones (unless they are extra delicious) without incident. So here is the opposite extreme from the folks who say their dogs don’t like it! Ha! I guess I’ll move the littler dog from Ollie to royal canin too. I moved the larger one to this food because she is having digest trouble with every other high end food I have tried.

Excellent Food for CANE CORSO

In my opinion for Cane Corso (my dog's name Callie) must eat Royal Canin 6 days and 1 day natural meat. This is just my exparices, when we take Caillie she was 2 month and at that time she was natural eater(meat, eaggs, currot e.t.). Slooly-slooly we give dry nutrition other premium brands, after 2 week she eat full week dry nutrition. We never buy 5kg nutrition to test, when dog frequently change nutrition, it's very bad for her immunsystem. We just tooked 3 top premium brands a new pack and test it.(changed by the guideline one nutrition to other). From 5th month Callie eat dry nutrition Royal Canin(6D). Now she's 12 month, very strong, healthy, clever. You can check our funny YouTube channel where she smile and happy :) Note. video with chocolate, - not real chocolate, we made smoozy with canin and homade yogurt ;) It just effective video where people educate each others.

Excellent Food choice for large breed

I adopted a Great Dane mix who was thin and underweight . The vet recommended using Jr Giant and my dog is now healthy with a wonderful shiny coat and has gained 10 lbs

Top quality dog food

We’ve been feeding Royal Canin to our Saint Bernard since he was a puppy. It’s the only brand I can find that offers puppy, junior and adult for the Giant breed. Royal Canin was recommended by our vet and it’s one of the few brands of dog food we trust. We’ve never had any intestinal issues with Royal Canin. Our 7 yr old Rhodesian Ridgeback also eats Royal Canin.

Great Food

[This review was collected as part of a promotion.] I am so glad I found this food as it was highly recommended by my Vet. I am impressed with all the research the company does to make sure each breed gets what they need, from nutriments, to the size of the kibble. While my dogs do not have a specific breed food, the Giant Breed is perfect for my English Mastiffs.
