As your dog ages, their dietary needs will change, and you may find you need to switch them onto a more tailored food. Dogs typically become seniors when they are 7+ years old, but this will vary between dogs and breeds. If you older dog is needing some extra support, it would be worth discussing your options with your vet and then gradually moving them onto a diet specifically formulated for their needs - perhaps with added joint support and extra vitamins, or one that factors in your dog's weight.
