Feeding & use

Follow the feeding guide printed on the bag, which sets daily portions based on your dog's current weight and activity level. Transition gradually over 7–10 days by mixing increasing amounts of the new food with your dog's current diet.

Keep fresh water available at all times, and store the kibble in a cool, dry place with the bag tightly sealed to preserve freshness. A consistent portion at mealtime helps senior dogs maintain a steady body condition.

A note on the name: this is a chicken-based recipe, so it is not a Royal Canin chicken free dog food. If you're looking for Royal Canin chicken free dog food for a dog that avoids chicken, ask our North York team about alternative protein formulas before you buy.
