Large breed dogs are susceptible to growth problems and illnesses if they are fed too quickly or issued the wrong type of food. Large breed dogs can gain an incredible amount of weight in their first year and many dog owners believe that since they recognize their dog is going to be big, that he or she should eat whenever they please. But that is far from the truth. Large breed dogs not only need to be on a regimented eating schedule (no open-grazing), they also need large breed dog food that is high in nutrients and doesn't have all the fatty ingredients that other dog foods may have. Excess weight can slow a large breed dog down and cause elbow and knee inflammation and joint pain over the years. Recognize the best type of large breed puppy food to buy and give your puppy the best chance to lead a happy and healthy life.
