Size Health Nutrition: Every size and age has unique needs

Dogs are incredible and come in every shape and size. But as they vary in size, life stage and lifestyle, their physiological needs do too. That’s why ROYAL CANIN®’s Size Health Nutrition range is carefully tailored to every dog’s specific needs.

Why health is not one-size-fits-all

Our dogs enrich our lives in every way. While their size has no bearing on how incredible they are, it does affect how their bodies work.


1.Different jaw sizes

All dogs have 42 teeth but different jaw sizes. For extra-small dogs, having so many teeth packed into a small mouth can lead to dental sensitivities.

2.Different digestive tracts

Large dog breeds have proportionally smaller digestive tracts than small dog breeds, meaning they're more susceptible to digestive sensitivities.

3.Different specificities

Compared to smaller breeds, the body mass of muscular and larger dog breeds puts extra pressure on their joints.

4.Different ageing periods

Size impacts ageing – smaller dogs reach their senior years at around 12 years old compared to larger dogs at 8 years old.

Find the right tailored nutrition for your dog

Did you know?

Extra-small dogs like the Chihuahua have a greater chance of developing urinary crystals and stones.
If your dog has been fed only dry food in the past, incorporating wet food into their diet benefits them by
supporting their urinary health, due to the higher moisture content in mixed food.

Mixed feeding benefits dogs of all sizes & ages

Our wet products are innovatively formulated to enhance your dog's feeding experience. Mixing dry and wet food in a bowl offers the benefits of both types while maintaining a balanced of healthy nutrients and aromas.

Dog dry food
