.."The principal feature of this exercise  is that the dog retrieve promptly .."

"The retrieve shall be executed at a brisk trot or gallop, the dog going directly to the dumbbell and retrieving it, and returning directly  to the handler without without unnecessary mouthing or playing.

The dog must sit straight to deliver, centered immediately in front of the handler's feet, close enough that the handler can readily take the dumbbell without moving either foot or having to stretch forward."

Minor to substantial deductions shall be made for  slowness in going out or returning, or in picking up the dumbbell, for not going directly to the dumbbell, for mouthing, playing with, or dropping the dumbbell, and for reluctance or refusal to release the dumbbell to the handler.

As always, "...it is essential that the dog demonstrate willingness and enjoyment of it's work"
