Dog food is plant or animal material intended for consumption by dogs or other canines. Special dog foods given as a reward, and not as a staple, are known as dog treats.Some people make their own dog food or feed their dogs meals made from ingredients purchased in grocery or health-food stores; many others rely on commercially manufactured dog food.There are many different recommendations on what diet is best for dogs. Some people argue that dogs have thrived off of leftovers and scraps from their human owners for thousands of years and that commercial dog foods (which have only been available for the past century) contain poor-quality meats, additives, and other ingredients dogs should not ingest, or that commercial dog food is not nutritionally sufficient for their dogs.
