Smaller breeds of puppies and grown dogs, as we’ve written about in our Yorkshire Terrier article, will have special requirements when they reach an older age. In contrast to larger dog breeds, they’ll be on the whole more susceptible to things like free radical damage than arthritis, which is more prevalent in bigger dogs at a later age. And antioxidants can aid in fighting this damage. So, like the dog food we’ve picked out for our Pedigree small dog food review for senior small breeds, antioxidants are going to be of relatively high priority within their diets. Antioxidants such as those C vitamins can be found within carrots, along with Vitamin E; and both are combined with supplementary sources in this senior dog food.
