Hi and welcone!
I wouldn't, if anything I would change to Purina Pro Plan Focus, chicken and rice. I would keep puppy on that until switching to an adult formula. (Disclaimer - I am not a fan of any Diamond products but that does not affect my advice.) I think it is best to keep a puppy on what the breeder was feeding through growing and discuss any change with them. Pro Plan is just a better quality without drastic change.
