Royal Canin Size Health Nutrition Medium Aging 10+
Royal Canin Size Health Nutrition Medium Aging 10+ is formulated specifically for medium-breed seniors with a kibble shape, calorie density and nutrient profile tuned to the metabolic and dental needs of older medium dogs. It holds its position for this use case by delivering precise, size-specific nutrition and joint support that many generic senior formulas do not provide, though it is typically priced higher than the mass-market options. Compared with the other grain-inclusive senior kibbles here, Royal Canin’s technical advantage is its targeted, veterinary-focused formulation that balances age- and size-specific requirements over broader ‘natural’ or cognitive-focused approaches.

Blue Buffalo Life Protection Formula Senior Chicken & Brown Rice
Blue Buffalo Life Protection Formula Senior Chicken & Brown Rice combines real chicken, brown rice and the brand’s LifeSource Bits antioxidant blend to support immune health and balanced nutrition in senior dogs who benefit from recognizable whole-food ingredients.
