Generally speaking, you should select a dog vitamin product that will improve your dog's quality of life and increase life span. The best dog vitamin product is one that has been prepared with natural, human grade ingredients, follows the latest nutritional guidelines and has the approval of the veterinary community. Low grade, commercial dog food contains certain additives and preservatives that act like toxins in your dog's body. The right dog vitamin product should include vitamins that function as antioxidants to combat the effects of these substances. The toxins could cause long term damage to your dog's system and trigger the development of serious health issues.
