A Strong Flip is a purposeful reorienting, cartwheeling, or flipping action in pursuit of a flying disc to the dog’s strong flipping side.
Dogs have a strong and a weak side when it comes to flipping. One side will yield better and more natural flips. That side is your dog’s strong side, and will yield the Strong Flip.
It is important to note that your dog’s Strong Flip might not be on your throwing hand side.
If your dog doesn’t flip both ways your flip is just strong.
