The Dog

That black dog is again at my heels
No one can see him but he sure is real
Leave me alone boy, go fetch this stick
But return not to sender, at least not too quick
I like dogs but I don't like this breed
I'm scared of his stealth, his hunger, his speed
He consumes one and all that crosses his path
A canine vacuum, a vader of darth
Run along now boy, you're not needed today
You're as sad as I am, so just go and play!
