A Reverse Vault
Essentially a flip off of a part of the handler's body, the Reverse Vault is a vault that stays on one side of the handler. If the dog starts the trick in front... is a vault in which the dog flips off the handler’s body.
The Reverse Vault
The dog uses the player´s body as a launching pad to jump for a disc. A Vault is a leaping catch from the handler’s body. The dog leaves the ground for the target..., aka Rebound, can be done off of any part of the body, and the part of the body that the vault happens from usually is reflected in the name: Reverse Leg Vault, Reverse Chest Vault, Reverse Back Vault.
Leg Rebound, Chest Rebound, Back Rebound, etc. is another popular phrasing.
Rebounds or Reverse Vaults tend to land on the same side of the handler from which the dog leapt.
