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's a good fit for owners looking to support aging joints, steady digestion, and overall vitality as their dog transitions into a more mature life stage.
If you're comparing life stages within the same line, you may also want to look at the Royal Canin Size Health Nutrition Large Breed Adult Dry Dog Food for younger adults, or the Royal Canin Size Health Nutrition Large Breed Aging 8+ Years Dry Dog Food for older seniors. Medium-breed owners can consider the Royal Canin Size Health Nutrition Medium Breed Adult 7+ Years Dry Dog Food.
Is this a chicken-based recipe?
Yes — this formula features chicken as a primary protein, so it is not a Royal Canin chicken free dog food option. If you're looking for chicken-inclusive recipes such as a Royal Canin chicken and rice dog food style diet, this large-breed senior 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 in a cool, dry place and keep it sealed to preserve freshness and kibble texture between feedings.
Available for same-day pickup at our North York, Toronto storefront, or ships Canada-wide.
