Please note the above 3 posts prior to your latest post. Otherwise it may be best to consult a veterinary health care professional as I suggested.
Puppies do best on a basic, simple, bland diet and don’t do well with changes.
Any quality puppy food will do. Consider Pro Plan Puppy. Although, it may be best to keep the pup on whatever the breeder has been feeding, at least for the first month or two. Just add some water. You can use a bit of the kibble for snacks also.
Adding too many different things could result in GI upset and diarrhea.
