Then feed twice daily until one year of age. Adult dogs can be fed either once or twice daily. Feed the puppy all it will eat in 15 minutes each feeding. Do not leave the food out continuously if you are trying to house-train the pup. Dry food is recommended over canned food because it is more economical and it is easier to store.
Dry food is also better for dental care.
The nutritional content is the same. If desired, a tablespoon of canned dog food can be mixed with the dry food to enhance the flavor. The puppy's diet should never be changed rapidly. The puppy might not eat the strange food, or if it does eat, develop diarrhea leading to dehydration and other complications. Diet changes should be made over a 2-4 week period to prevent digestive upsets.
