How would I make an animation stop when the user hits the ground?

So, I'm trying to make a sort of dash, but it's in a move for an ability for my game. I got the move down, but the animation for the dash doesn't stop right. The animation just kind of pauses for a few seconds, then stops. Gyazo of what happens: https://gyazo.com/26c9866598398e9732e58a5b416274e4
