FANCY DID FANTASTIC!!!
That was a beautiful find Very nice work.
Yes, she does enjoy playing with the tin when you start working on leave its/ drops/ touches. I think SHE thinks you are playing with it WITH her. The actual search was very nice.
My suggestion would be to do more hides like this one and pay attention to her alert. Next time, get into the action sooner…like when she starts digging around. THAT might be your alert. For example. She locates it and starts digging…you recognize the digging as an alert and go to her…”did you find one? Show me” (or something similar)…root around with her and click when she touches it…immediately treat and pick it up…put it in your pocket and praise some more and drag out the treats (or play or pet) “That was brilliant. Good girl!”
