Approximately how much does the puppy weigh?
How is his health? Is he active and healthy looking? Has he been in for a vet check-up yet? How is his poop?
That's a fine food for a puppy, not too hard. It could be too much. I think I fed my puppies about that much, maybe even less (I can't remember) when they were that age and they were in the high teens/low 20s for weight. They were on the larger side.
