This puppy has a lot of natural retrieving instinct, so it is best to do little more than encourage the pup to retrieve at this point. As they get older, you can start adding refined working retriever behavior.
BTW, this is the same dog as a young adult:
Wow. That is SO opposite what I expected to see. The focus was on the delivery, it was almost like the going out was incidental. Huh. Very interesting.
More than one way to do things.
