Veterinary ophthalmologist, things to consider
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. 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. Vitamin B complex (including folic acid) and B2 (riboflavin) support eye health in general, but Vitamins C and E, along with Vitamin A, are the real dog vitamin heavy hitters when it comes to vision problems.
