I have not tried it, but have heard so much about it from my dog friends in MI. They seem to really love it!
I think Shellbell does it...I think....
I did nosework with Charlie, I know it's not the same, but we really enjoyed that. So very different from Obedience or Agility, but boy was it nice to have a bit of training under our belts. Made us more in tune with one another while searching, and helped to keep him under control while we waited to go.
Have fun! I hope to hear more about it, and of course how is Lucy doing?!
