Pra disease, what they say
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. Loss of vision is one of them. Your ideal dog vitamin should include Vitamin A, which is essential to good vision health and may reduce cataracts. Vitamin A and its precursor beta carotene act as powerful antioxidants that destroy carcinogens and support the immune system.
