archer66, here is something you might consider using. This is a photo of a young pup. She was older than yours (9 months) and was well past FF at the time. Daisy was a very precocious pup (like yours).
At that age, she was running a tower shoot......the youngest by far working that day. "Euro" shoots mean many exciting retrieves, adrenelin "boosts" and distractions including often crippled, big rooster pheasants .
In order to have more control over her delivery, she was wearing a short tab. This allowed me to take hold of it and "settle her down" before asking her to "give" any retrieve. It provided the opportunity to impress upon her, "Hey....remember me? and what you are supposed to do?" The focus was on responsiveness.
Here's a link for all the photos featuring Daisy's tab.
