Thanks everyone! I think Darcy is going to be quite the little agility dog one day.
One thing he will have to stop is his biting of the back of my legs when he gets over excited (he did it just after he missed the jump after the tire).
I sent the video to his breeder who called him devil Darcy, haha! And my dad calls him the little monster. But really we all just love him to pieces, he's a great pup and was worth the wait.
