Senior dog food is designed to keep dogs healthy as they age. They can provide them with a balance of nutrients that are more suited to elderly dogs than traditional dog food.
In addition, they contain ingredients that can aid the maintenance of healthy joints, strong bones, and digestion. There are dry and wet varieties of senior dog food commonly available.
Do you recommend Royal Canin ISO for senior dogs? (Mine is a 10-yr. old Pembroke Welsh Corgi.)
