Switch to Adult Dog Food

Just like a human child and human adult have a different metabolism and biology, so too do a puppy and an adult dog. As a general rule of thumb, dogs under one year old are considered puppies. Puppies require a specific blend of nutrients to make sure they grow and develop properly. They are also extremely energetic and require high-calorie and high-protein diets.
By the time your puppy reaches adulthood, they will need to switch their kind of food.
