Deb Z. started us on it a couple of months back. While she's super prey driven, she didn't want to take the "stick" on "my" terms because that "wasn't fun". So she showed me how to shape her into taking it, however I wasn't exactly sure how to go from there. I only knew what I've seen from my parents and then ordered a couple of DVD's on the Apport i.e Ivan Balabanov etc. and I watched "Anleeren" youtube video over and over and over again.
Still not quite sure if what I'm doing is right, but it seems to work. She's holding.
