Okay, you can clap now. Ha!
This is one of those times when clicker training is so helpful. Although I am not using a clicker (to avoid exciting the other dogs in the house), Riley is still very used to offering behaviors that are marked and rewarded when correct. While I had some ideas of my own, it is also fun to see what the dog comes up with as well. "Pig nose" was something Riley dreamed up and I simply marked it so she would repeat it.
