Fun clip, nice to watch how her drive goes up and down with the different toys. I enjoyed her reaction to the dumb bell and how you built up her curiosity and drive prior to her grip. She's a sweet pup. Are you keeping her (probably you've already said you are or aren't but I've not been keeping up).
If she continues to show such promise, she is staying here whether she turns out as a show/breeding grump or not.
I am so sorry the clip stopped when it did, she is routinely fetching the metal scent article to hand, and she really loves to tug. She is going to be lots of fun!
