Royal Canin - Size Health Nutrition Large Breed Adult 5+ Years Dry Dog Food

TL;DR: Royal Canin Large Breed Adult 5+ is a dry dog food formulated for mature large-breed dogs (roughly 56–100 lb) aged 5 years and older. It uses chicken as the primary protein and features size-appropriate kibble with nutrients that support aging joints, digestion, and everyday vitality.

This Royal Canin formula is built for the needs of older big dogs, combining joint support and digestive care in one daily diet. The recipe pairs highly digestible proteins with fibres and prebiotics to help support gut health as dogs move into a more mature life stage.

The crunchy kibble is shaped and textured for larger jaws, making it practical for everyday feeding. Note that this is a chicken-inclusive recipe, so it is not a chicken-free option — if you searched for royal canin chicken free dog food, this diet features chicken as its primary protein instead.

Who is it for?

This food is made for mature large-breed adult dogs aged 5 years and older, typically weighing between 56 and 100 lb. It suits owners who want to support aging joints, steady digestion, and overall vitality as their dog transitions into its senior years.

Because many large dog breeds mature earlier than smaller ones, a 5+ formula can be a sensible fit even for active dogs. If you're comparing options across dog breeds and life stages, you may also like the Royal Canin - Size Health Nutrition Large Breed Aging 8+ Years Dry Dog Food for older seniors, the Royal Canin - Size Health Nutrition Large Breed Adult Dry Dog Food for younger adults, or the Royal Canin - Size Health Nutrition Small Breed Adult 8+ Years Dry Dog Food for smaller households.

Is this a chicken-based recipe?

Yes — this is a royal canin chicken dog food recipe with chicken as the primary protein, so it isn't chicken-free. If you prefer a chicken-inclusive diet for your large-breed senior, this formula fits that profile while being tailored to mature big dogs.

Feeding & use

Feed daily as a complete diet, adjusting portions based on your dog's weight, activity level, and body condition. Follow the feeding guide printed on the bag and transition gradually from your previous food over 7–10 days.

Always provide fresh water, and consult your veterinarian if you have questions about your dog's specific needs. Store the 100 lb bag sealed in a cool, dry place to preserve freshness and kibble texture between feedings.
