You type in any command: the usual - sit, lay down, roll over, beg, play dead -whatever.
But be experimental -you might as well type in commands that aren't used at all; it'll be fun to see the reaction of the too-cute terrier on this website!
Oh, and don't forget to type in 'Kiss' as well. But do that last...
Have fun.
