I agree with the above advice. The dog is awful young and the retrieving portion of the training isn't that big of deal at this point. But I'm wondering why no one has said anything about the NO command. If it isn't something the dog already knows then it should be. Sounds to me like the dog is just sort of playing with this behavior. If you aren't playing at the time then a stern NO should let the dog know that what she is doing is not what you want.

Just my opinion, may be too simple minded?
