When I say, "bang", my dog starts limping, then I say, "bang", again and she starts crawling, then I say, "bang" one last time and she rolls on her side and dies. Except for her tail; can't kill that no matter how hard I try!
I've taught my dog to sneeze on command! It's great fun to show my friends and family, and people never get tired of it. I've also taught him to use his "inside voice". I'll tell him to speak, which elicits a normal bark. Then I'll bend over slightly and say, "Shh, inside voice." He'll give a very soft "woof" in response.
