Royal Canin® Size Health Nutrition™ Giant Junior Dry Dog Food

Royal Canin

GIANT Junior is formulated to meet the unique nutritional needs of giant breed puppies from 8 months to 18/24 months old, over 100 lbs.


Features and Benefits


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.
