Shake?

Whiskey, my corgi, knows the basic commands: sit, lay down, up/dance, and roll over. For the past few weeks I have been trying to teach a few new ones: speak and shake. She almost has the speak down, she does more of a little low growly bark, but none-the-less she "said" something. The shake, she has NO clue what to do, I try putting the treat in my first and putting it near her paw, she just ends up nosing it, sniffing it, and licking my hand up and down. Which leads me to my question: Can corgi's shake? You know with those little bitty legs and all. Just curious, and will keep trying for it
