I just sent sully a little note on the same thing, But basically, at this stage, we would take her off of fetching for a couple of MONTHS, and work her on strict obedience. The we would go to plastic dummies, and work on the hold command. For our string, That means you hold it still, and in the middle. Ithink that at htree months, you just need to slow her down a bit. She has already shown that she wants to fetch, and this desire will not suddenly leave her over the next two months. Also, I like to work on hold in the winter, because we can do some of it inside.
