Certain dog vitamins address a specific health problem, such as age related vision issues. Dogs age just as we do, and that aging process triggers health issues that are similar to those that we experience. One of these issues involves vision deterioration. Vitamin A is essential to good vision health and may reduce the incidence of cataracts, so be sure to look for a dog vitamin product that contains plenty of this vitamin. Vitamin A and its precursor beta carotene are both super antioxidants that destroy carcinogens and boost immune function.
