Royal Canin Medium Adult 7+ promises good skin, good dental health, and delayed onset of old age. When your medium breed shows the following signs, it might mean they’re reaching old age: their sense of smell isn’t as acute as always, they tend to get ill more often, their immunity starts to crumble and their digestive system gets more sensitive. They moult slower and their coat gets dull. Tartar builds up more easily with all sorts of dire consequences. Trust Royal Canin Medium Adult +7 to help with your dog’s optimal health.
