Some posts on dog vision problems
Certain dog vitamins address a specific health problem, such as age related vision issues. Dogs experience an aging process that is similar to ours and triggers similar health issues. 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.
