I just chop em up into little bits. Since our kitchen is close when I start chopping I say OOOH BOOOOYYY , lol, and she starts screaming..she knows the fun is about to begin.
I let her just take one bit for a lil thing, but if she does good she gets to buffet in my hand for a few seconds. I've read and found that reinforces the good stuff to "jackpot" em. Since I live in the south, I just call it a buffet.

Try it!
Currently, she gets a click/treat when I bump my hand into the ring when I cue her with "gimme the ring". Slowly, she's gettin it.
Even if she don't get it, she's wicked cute just holding that shower curtain ring.
