retrieving problem
 

I have a black lab and she dose well with sitting and staying, when I throw the dummy she wont break. I'll tell her to go get it and she will do just fine and go up and grab it, but halfway back she will start playing with it. I dont want to punish her because she did so well up till then. How can I get the message over to her that I want her to bring it to me?

Initially, use a long lead and reel her in. For the best long term results, Force Fetch is your answer.

Second that.
