First Mary, world's worst dog trainer?? HARDLY!!!! I think we covered that in another thread.

Nah, I think Rakins is just confused or did just need a wild day in the mud.

Also, not sure how long or much you've been working on that particular trick, but sometimes (I've found) they get tired of trying to do the same thing constantly, esp if they get a bit confused, so a break, even for a few days sometimes works wonders. I know right now I'm working on "wipe your paws" with Makena, and I could tell she was getting confused last week - she knows to wipe one paw, or the other paw, but I can't get her to do one paw then the other paw - and we worked really hard. I've given her this week off, and we'll start up again this weekend. I've found that when I give her a few days off from a particular trick when we've hit a wall, sometimes we start up again and she's almost like
oh, so THAT'S what you wanted, I get it now!! Sometimes just a little break (for both of us) is a good thing.
And Sara, I used a post-it, much like your painters tape - and clicked Makena's paw on her face/nose - she got that one really quickly. Once she got it, I then would only click after she held it for couple seconds, then increased it to a few seconds, etc. Now she's shameless, it's her default trick - just look at her, and "she's shy". She'll do it anywhere, for anyone, anytime (cuz she gets so much mileage from it). Heavens!!

(and she's anything BUT).
